In 1995, Java was developed by Sun Microsystem.
It is a high leveled and widely used programming language.
For many years, Java is one of the most popular programming languages.
It provides support for primitive data types like char, int, etc. because it is not considered as pure object-oriented.
First Java codes are compiled into byte code and then it is runs on a Java Virtual Machine regardless of the underlying architecture.
Java syntax are similar to C / C++ .It does not provide low-level programming functionalities like pointers.
Java codes are always written in the form of classes and objects.
It is used in all kinds of applications like web application, mobile application, desktop application, client-server application, enterprise application and many more.
Java does not allow many things which may lead to bad/inefficient programming if used incorrectly so, only Java codes are generally more maintainable.
The programs are written in Java typically run faster than corresponding Python programs and slower than C++. Like C++, Java does static type checking, but Python does not, when compared with Python.

Example

public class Main {
  public static void main(String[] args) {
    System.out.println("Welcome to Wikitechy");
  }
}

What are the major features of Java programming ?

webmaster — Tue, 03 May 2022 06:11:35 +0000

The primary objective of Java programming language creation was making it simple, secure and portable programming language.
In Java programming language there are some excellent features which play an important role in the popularity.
Features of Java are otherwise known as Java Buzzwords.

Features of Java:

Simple :

Java is very easy to learn and its syntax is easy, simple, and clean to understand.
In Java there is an Automatic Garbage Collection so no need to remove unreferenced objects.
In Java syntax is based on C++ which makes easier to write the program in it.

Secure :

Java is secure because it has features like bytecode verifier, no explicit pointer, automatic memory management that enhances the security of java programs.
Java also provides Exception handling and which makes it more secured.

Portable :

Java supports write-once-read-anywhere (WORA) approach.
In every machine we can execute the Java program and (.java) is converted into (.class)which can be easily runs.

Distributed :

In Java it is distributedbecause it facilitates users to create distributed applications.
On internet or network running on one machine can easily access the resources of another machine.
Remote Method Invocation and Enterprise Java Beans are mostly used for distributed programming.

Multithreaded :

In multithreaded programming more than two parts of a program can execute simultaneously inside a machine.
Simultaneously a single program can do two or more than two tasks.
Simultaneously multithreading is a special form of multitasking. For example, in a multithreaded program you can read a file in one thread and can write into a different file in other thread.

High Performance :

Compare to another program language Java is faster because bytecode is “close” to native code.
Java is an interpreted language that is why it is slower than compiled languages like C, C++, etc.

Robust :

It uses a strong memory management so that it is a strong programming language.
The concepts like Exception handling, Automatic garbage collection, etc. make it more robust.

Interpreted :

For program execution Java uses Just-In-Time (JIT) interpreter along with the compiler.

Dynamic :

Java supports the dynamic loading of classes.
It also supports functions from its native languages like C++ and C.

Architecture Neutral :

It does not depend on architecture organization of memory, CPU input/output, processor of a computer.
It also makes java as an architecture neutral language, something which is not dependent strongly on specific system configuration, bytecode is platform independent.

Platform Independent :

It needs platform to be executed which is different from other programming languages like C and C++.
It does not depend upon the operating system to be executed.

Object-Oriented :

It supports the principles of object-oriented programs like Abstraction, Inheritance, Polymorphism, Encapsulation, etc.
Java focus on object while other programming languages like C, FORTRAN, PASCAL are focus on logics.

Difference between wait() and sleep() in java ?

Difference between wait() and sleep() in java ?

Wait() Method	Sleep() Method
wait() Method of thread class goes in waiting state and it won’t come back automatically until we call the notify() or notifyAll().	sleep() is a method which is used to pause the process for few seconds or the time we want too.
It is called on Object.	It is called on Threads.
It is an instant member of java.lang.Object class.	It is a static member of java.lang.Thread class.
wait() releases the lock or monitor.	sleep() doesn’t releases the lock or monitor while waiting.
wait() is used for inter-thread communication.	sleep() is used to introduce pause on execution, generally.
It must be called within the synchronized blocks.	It may be called from within or outside the synchronized block.
wait() Example synchronized(LOCK) { LOCK.wait(); // LOCK is not held }	sleep() Example synchronized(LOCK) { Thread.sleep(1000); // LOCK is held }

Difference between ClassNotFoundException and NoClassDefFoundError in java ?

Editor — Wed, 14 Jul 2021 00:03:41 +0000

Difference between ClassNotFoundException and NoClassDefFoundError in java ?

ClassNotFoundException and NoClassDefFoundError occur when a particular class is not found at runtime. However, they occur at different scenarios.
ClassNotFoundException is an exception that occurs when you try to load a class at run time using Class.forName() or loadClass() methods and mentioned classes are not found in the classpath.
NoClassDefFoundError is an error that occurs when a particular class is present at compile time, but was missing at run time.

NoClassDefFoundError	ClassNotFoundException
NoClassDefFoundError is an error. It is the type of java.lang.Error.	ClassNotFoundException is an exception. It is the type of java.lang.Exception.
It occurs when java runtime system doesn’t find a class definition, which is present at compile time, but missing at run time.	It occurs when an application tries to load a class at run time which is not updated in the classpath.
It is thrown by the Java Runtime System.	It is thrown by the application itself. It is thrown by the methods like Class.forName(), loadClass() and findSystemClass().
It occurs when required class definition is missing at runtime.	It occurs when classpath is not updated wih required JAR files.

Difference between JDK JRE and JVM ?

Difference between JDK JRE and JVM ?

JDK

Java Development Kit is the core component of Java Environment and provides all the tools, executables and binaries required to compile, debug and execute a Java Program.
JDK is a platform specific software and thats why we have separate installers for Windows, Mac and Unix systems.
We can say that JDK is superset of JRE since it contains JRE with Java compiler, debugger and core classes. Current version of JDK is 1.7 also known as Java 7.

JVM

JVM is the heart of java programming language. When we run a program, JVM is responsible to converting Byte code to the machine specific code.
JVM is also stage dependent and provides core java functions like memory management, garbage collection, security etc.
JVM is customizable and we can use java options to modify it, for example allocating minimum and maximum memory to JVM. JVM is called virtual because it delivers a interface that does not depend on the underlying operating system and machine hardware.
This independence from hardware and operating system is what makes java program write-once run-anywhere.

JRE

JRE is the implementation of JVM, it provides platform to execute java programs. JRE consists of JVM and java binaries and other classes to execute any program successfully.
JRE doesn’t contain any development tools like java compiler, debugger etc.
If you want to execute any java program, you should have JRE installed but we don’t need JDK for running any java program.

JDK	JRE	JVM
Java Development Kit	Java Runtime environment.	Java Virtual Machine.
Kit providing the platform to develop and execute/run the java program.	It is an installation package which provides environment to only run(not develop) the java program (or application)onto your machine.	Whatever Java program you run using JRE or JDK goes into JVM and JVM is responsible for executing the java program line by line hence it is also known as interpreter.
JDK is only used by Java Developers.	JRE is only used by them who only wants to run the Java Programs (i.e). end users of your system.	It is in-built in both JDK and JRE.

Java program to find second largest number in an array ?

Editor — Wed, 14 Jul 2021 00:03:30 +0000

Java program to find second largest number in an array ?

Given an array of integers, our task is to write a program that efficiently finds the second largest element present in the array.

Algorithm:

Initialize two variables first and second to INT_MIN as,
- first = second = INT_MIN

- Start traversing the array,

a) If the current element in array say arr[i] is greater than first. Then update first and second as,

- second = first
- first = arr[i]

- second = arr[i]

Return the value stored in second.

step 1

Iterate the given array.

Step 2 (first if condition arr[i] > largest):

If current array value is greater than largest value then move the largest value to secondLargest and make current value as largest

Step 3 (second if condition arr[i] >secondLargest )

If the current value is smaller than largest and greater than secondLargest then the current value becomes secondLargest.

Sample code in Java

public class SecondLargest {
     
    	public static void main(String[] args) {
     
    		int arr[] = { 24, 56, 57, 105, 102, 62, 58, 46, 76, 95 };
    		int largest = arr[0];
    		int secondLargest = arr[0];
    		
    		System.out.println("The given array is:" );
    		for (int i = 0; i < arr.length; i++) {
    			System.out.print(arr[i]+"\t");
    		}
    		for (int i = 0; i < arr.length; i++) {
     
    			if (arr[i] > largest) {
    				secondLargest = largest;
    				largest = arr[i];
     
    			} else if (arr[i] > secondLargest) {
    				secondLargest = arr[i];
     
    			}
    		}
     
    		System.out.println("\nSecond largest number is:" + secondLargest);
     
    	}
    }

Output

The given array is:
24	56	57	105	 102  62  58  46  76  95	
Second largest number is:102

Java Program to reverse a Linked List ?

Editor — Wed, 14 Jul 2021 00:03:25 +0000

Java Program to reverse a Linked List ?

A Linked list contains two things data and the address of the node each node is linked to the next node.
There can be two solution to reverse a linked list in java.
- Iterative
- Recursive

Iterative

Here we have three nodes i.e previousNode, currentNode and nextNode
When currentNode is starting node, then previousNode will be null
Assign currentNode.next to previousNode to reverse the link.
In each iteration move currentNode and previousNode by 1 node.

public static Node reverseLinkedList(Node currentNode)
	{
		// For first node, previousNode will be null
		Node previousNode=null;
		Node nextNode;
		while(currentNode!=null)
		{
			nextNode=currentNode.next;
			// reversing the link
			currentNode.next=previousNode;
			// moving currentNode and previousNode by 1 node
			previousNode=currentNode;
			currentNode=nextNode;
		}
		return previousNode;
	}

Sample Code in Java:

public class LinkedList{
 
	private Node head;
 
	private static class Node {
		private int value;
		private Node next;
 
		Node(int value) {
			this.value = value;
 
		}
	}
 
	public void addToTheLast(Node node) {
 
		if (head == null) {
			head = node;
		} else {
			Node temp = head;
			while (temp.next != null)
				temp = temp.next;
 
			temp.next = node;
		}
	}
 
 
	public void printList(Node head) {
		Node temp = head;
		while (temp != null) {
			System.out.format("%d ", temp.value);
			temp = temp.next;
		}
		System.out.println();
	}
 
	// Reverse linkedlist using this function 
	public static Node reverseLinkedList(Node currentNode)
	{
		// For first node, previousNode will be null
		Node previousNode=null;
		Node nextNode;
		while(currentNode!=null)
		{
			nextNode=currentNode.next;
			// reversing the link
			currentNode.next=previousNode;
			// moving currentNode and previousNode by 1 node
			previousNode=currentNode;
			currentNode=nextNode;
		}
		return previousNode;
	}
 
	public static void main(String[] args) {
		LinkedList list = new LinkedList();
		// Creating a linked list
		Node head=new Node(5);
		list.addToTheLast(head);
		list.addToTheLast(new Node(6));
		list.addToTheLast(new Node(7));
		list.addToTheLast(new Node(1));
		list.addToTheLast(new Node(2));
 
		list.printList(head);
		//Reversing LinkedList
		Node reverseHead=reverseLinkedList(head);
		System.out.println("After reversing");
		list.printList(reverseHead);
 
	}
 
}

Output :

5 6 7 1 2 
After reversing
2 1 7 6 5

Recursive Method:

Divide the list in two parts – first node and rest of the linked list.
Call reverse for the rest of the linked list.
Link rest to first.
Fix head pointer

Why do we need garbage collection ?

Editor — Wed, 14 Jul 2021 00:03:15 +0000

Why do we need garbage collection ?

Java garbage collection is the method by which Java programs achieve automatic memory management.
Java programs compile to bytecode which will be run on a Java Virtual Machine.
Once java programs run on the JVM, objects are created on the heap, which is a portion of memory dedicated to the program. Finally, some objects cannot be required.
The garbage collector finds these unused objects and deletes them to free up memory.

How Java Garbage Collection Works

Java garbage collection is an automatic process.
The programmer does not need to explicitly mark objects to be deleted. The garbage collection implementation lives in the JVM. Every JVM will implement garbage collection however it satisfies the only requirement is that it meets the JVM specification.
Although there are many JVMs, Oracle’s HotSpot is the most common. It offers a robust and complete set of garbage collection options.
While HotSpot has multiple garbage collectors that are optimized for various use cases, all its garbage collectors follow the same basic process.
- In the first step, unreferenced objects are identified and marked as ready for garbage collection.
- In the second step, marked objects are deleted.
- Optionally, memory can be compacted after the garbage collector deletes objects, so remaining objects are in a contiguous block at the start of the heap. The compaction process makes it easier to allocate memory to new objects sequentially after the block of memory allocated to existing objects.
All of HotSpot’s garbage collectors implement a generational garbage collection strategy that categorizes objects by age. The rationale behind generational garbage collection is that most objects are short-lived and will be ready for garbage collection soon after creation.

The heap is divided into three sections:

Young Generation

Newly created objects start in the Young Generation. The Young Generation is further subdivided into an Eden space, where all new objects start, and two Survivor spaces, where objects are moved from Eden after surviving one garbage collection cycle.
When objects are garbage collected from the Young Generation, it is a minor garbage collection event.

Old Generation:

Objects that are long-lived are ultimately moved from the Young Generation to the Old Generation. When objects are garbage collected from the Old Generation, it is a major garbage collection event.

Permanent Generation:

Metadata classes and methods are stored in the Permanent Generation. Classes that are no longer in use may be garbage collected from the Permanent Generation.

Needs of Java Garbage Collection

The benefit of Java garbage collection is that it automatically handles the deletion of unused objects or objects that are out of reach to free up memory resources.
Programmers working in languages without garbage collection (like C and C++) must implement manual memory management in their code.
Some programmers maintain in favor of manual memory management over garbage collection, primarily for reasons of control and performance.
While the discussion over memory management approaches continues to rage on, garbage collection is now a standard component of many popular programming languages.
For situations in which the garbage collector is negatively impacting performance, Java offers several options for tuning the garbage collector to improve its efficiency.

Find number of occurrence of each of the unique characters in a string ?

Editor — Wed, 14 Jul 2021 00:03:09 +0000

Find number of occurrence of each of the unique characters in a string ?

In this program an approach using Hashmap in Java.
- Declare a Hashmap in Java of {char, int}.
- Traverse in the string, check if the Hashmap already contains the traversed character or not.
- If it is present, then increase its count using get() and put() function in Hashmap.
- Once the traversal is completed, traverse in the Hashmap and print the character and its frequency.

Example

Input: str = "Wikitechy"
Output: 
        W 1
        i 2
        k 1
        t 1
        e 1
        c 1
        h 1
        y 1

Sample Code in Java

// Java prorgam to count frequencies of 
// characters in string using Hashmap 
import java.io.*; 
import java.util.*; 
class OccurenceOfCharInString { 
	static void characterCount(String inputString) 
	{ 
		// Creating a HashMap containing char 
		// as a key and occurrences as a value 
		HashMap charCountMap = new HashMap(); 

		// Converting given string to char array 

		char[] strArray = inputString.toCharArray(); 

		// checking each char of strArray 
		for (char c : strArray) { 
			if (charCountMap.containsKey(c)) { 

				// If char is present in charCountMap, 
				// incrementing it's count by 1 
				charCountMap.put(c, charCountMap.get(c) + 1); 
			} 
			else { 

				// If char is not present in charCountMap, 
				// putting this char to charCountMap with 1 as it's value 
				charCountMap.put(c, 1); 
			} 
		} 

		// Printing the charCountMap 
		for (Map.Entry entry : charCountMap.entrySet()) { 
			System.out.println(entry.getKey() + " " + entry.getValue()); 
		} 
	} 

	// Driver Code 
	public static void main(String[] args) 
	{ 
		String str = "Wikitechy"; 
		characterCount(str); 
	} 
}

Output
c 1
t 1
e 1
W 1
h 1
i 2
y 1
k 1

How to optimally divide an array into two subarrays so that sum of elements in both are same ?

Editor — Wed, 14 Jul 2021 00:03:02 +0000

How to optimally divide an array into two subarrays so that sum of elements in both are same ?

There are two methods used to split arrays,

Given an array of integers greater than zero, find if it is possible to split it in two subarrays (without reordering the elements), such that the sum of the two subarrays is the same. For example,

Input : Arr[] = { 1 , 2 , 3 , 4 , 5 , 5  }
Output :  { 1 2 3 4 } 
          { 5 , 5 }

Given an array of integers, find if it’s possible to remove exactly one integer from the array that divides the array into two subarrays with the same sum. For Example,

                           Input:  arr = [6, 2, 3, 2, 1]
                           Output:  true

On removing element 2 at index 1, the array gets divided into two subarrays [6] and [3, 2, 1] having equal sum.

Sample Code in Java

/ Java program to split an array 
// into two equal sum subarrays 
import java.io.*;

class Wikitechy {

    // Returns split point. If 
    // not possible, then return -1. 
    static int findSplitPoint(int arr[], int n) {

        int leftSum = 0;

        // traverse array element 
        for (int i = 0; i < n; i++) {
            // add current element to left Sum 
            leftSum += arr[i];

            // find sum of rest array 
            // elements (rightSum) 
            int rightSum = 0;

            for (int j = i + 1; j < n; j++)
                rightSum += arr[j];

            // split point index 
            if (leftSum == rightSum)
                return i + 1;
        }

        // if it is not possible to 
        // split array into two parts 
        return -1;
    }

    // Prints two parts after finding 
    // split point using findSplitPoint() 
    static void printTwoParts(int arr[], int n) {

        int splitPoint = findSplitPoint(arr, n);

        if (splitPoint == -1 || splitPoint == n) {
            System.out.println("Not Possible");
            return;
        }

        for (int i = 0; i < n; i++) {
            if (splitPoint == i)
                System.out.println();

            System.out.print(arr[i] + " ");

        }
    }

    // Driver program 

    public static void main(String[] args) {

        int arr[] = {1,1,0,2};
        int n = arr.length;
        printTwoParts(arr, n);

    }
}

Output

How to find next greater element for every element in an array ?

Editor — Wed, 14 Jul 2021 00:02:50 +0000

How to find next greater element for every element in an array ?

In an array, to display the Next Greater Element (NGE) for every element.
The Next greater Element for an element x is the first greater element on the right side of x value in an array.
While the elements for which no greater element exist, consider the next greater element as 0.

For any array, rightmost element always has next greater element as 0.
Next greater element of an array element array[i], is an integer array[j], such that
- array[i] < array[j]
- i < j
- j – i is minimum
i.e. array[j] is the first element on the right of array[i] which is greater than array[i].
For Example the Input array is 88, 13, 44, 2, 10, 5, 17

Output

Next greater element for 13     = 44
Next greater element for 2      = 10
Next greater element for 5      = 17
Next greater element for 10     = 17
Next greater element for 17     = 0
Next greater element for 44     = 0
Next greater element for 88     = 0

Steps for finding a next greater element

To find Next Great Element Using two loops.
All the elements one by one to picks in the outer loop.
The outer loop picked the first greater element from the inner loop.
If a greater element is found then that element is printed as next, otherwise 0 is printed.

Sample Code in Java

class Wikitechy
{ 
	/* prints element and NGE pair for 
	all elements of arr[] of size n */
	static void printNGE(int arr[], int n) 
	{ 
		int n1, i, j; 
		for (i=0; i		{ 
			n1 = 0; 
			for (j = i+1; j			{ 
				if (arr[i] < arr[j]) 
				{ 
					n1 = arr[j]; 
					break; 
				} 
			} 
			System.out.println(arr[i]+" -- "+n1); 
		} 
	} 
	
	public static void main(String args[]) 
	{ 
		int arr[]= {30, 35, 11, 17, 2}; 
		int n = arr.length; 
		printNGE(arr, n);
        
	} 
}

Output

30 -- 35
35 -- 0
11 -- 17
17 -- 0
2 -- 0

How to Count Occurrence of a given Character in a String in Java ?

The number of occurrences of each character to be count and also the occurrences of duplicate characters it should not be display repeatedly. The following steps are given below,
- First, we split the strings by spaces.
- Take a variable count = 0 and in every true condition we increment the count by 1.
- Now run a loop at 0 to length of string.
- And then check if our string is equal to the word.
- If condition true then we increment the value of count by 1.

Sample Code in Java

class wiki{
	public static void main (String[] args) {
	String str = "Welcome to wikitechy website. Wikitechy is the best website to learn technology."
String findStr = "wikitechy";
int lastIndex = 0;
int count = 0;

while(lastIndex != -1){

    lastIndex = str.indexOf(findStr,lastIndex);

    if(lastIndex != -1){
        count ++;
        lastIndex += findStr.length();
    }
}
System.out.println(count);
	}
}

How to Copy One Array to Another in Java

Java provides inbuilt methods to copy array. Whether we want a full copy or partial copy of array, we can do it easily using java inbuilt classes.

Object.clone():

Object class provides clone() method and since array in java is also an Object, we can use this method to achieve full array copy.
If you want partial copy of the array we cant’t use this method.

Sample Code in Java

public class Wiki
{ 
	public static void main(String[] args) 
	{ 
		int a[] = {2, 8, 3}; 

		// Copy elements of a[] to b[] 
		int b[] = a.clone(); 

		// Change b[] to verify that b[] is different 
		// from a[] 
	 

		System.out.println("Values of a[] "); 
		for (int i=0; i			System.out.print(a[i] + " "); 

		System.out.println("\n\nValues of b[] "); 
		for (int i=0; i			System.out.print(b[i] + " "); 
	} 
}

Output

Values of a[] 
2 8 3 

Values of b[] 
2 8 3

How to check if two rectangles intersect or not ?

How to check if two rectangles intersect or not ?

- The following standard Java coding practices to solve this problem.
- We have an encapsulated two co-ordinates in a Point class and have Rectangle has two Point instance variable and an instance method like equals() to check if another rectangle is overlapping or not.

A rectangle can be represented by two coordinates, top left, and bottom right. As part of the problem you will be given four coordinates L1, R1 and L2, R2, top left and bottom right coordinate of two rectangles and you need to write a function isOverlapping() which should return true if rectangles are overlapping or false if they are not.

Sample Code in Java:

public class Main {

  public static void main(String[] args) {
  Point l1 = new Point(0, 10);
  Point r1 = new Point(10, 0);
  Point l2 = new Point(5, 5);
  Point r2 = new Point(15, 0);

  Rectangle first = new Rectangle(l1, r1);
  Rectangle second = new Rectangle(l2, r2);

  if (first.isOverLapping(second)) {
  System.out
  .println("Yes, two rectangles are intersecting with each other");
  } else {
  System.out
  .println("No, two rectangles are not overlapping with each other");
  }
  }

}

class Point {
  int x;
  int y;

  public Point(int x, int y) {
  super();
  this.x = x;
  this.y = y;
  }
}

class Rectangle {

  private final Point topLeft;
  private final Point bottomRight;

  public Rectangle(Point topLeft, Point bottomRight) {
  this.topLeft = topLeft;
  this.bottomRight = bottomRight;
  }

  public boolean isOverLapping(Rectangle other) {
  if (this.topLeft.x > other.bottomRight.x // R1 is right to R2
  || this.bottomRight.x < other.topLeft.x // R1 is left to R2
  || this.topLeft.y < other.bottomRight.y // R1 is above R2
  || this.bottomRight.y > other.topLeft.y) { // R1 is below R1
  return false;
  }
  return true;
  }

}

Output

Yes, two rectangles are intersecting with each other
