Example

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

Output

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.
