What is Linear Sort in Java ?

  • One of the simplest Sorting techniques is a linear sort.
  • Linear sort is the selection of an element and keeping it in sorted order.
  • In linear sort, the strategy is to find the smallest number in the array and exchange it with the value in first position of array.
  • Now, find the second smallest element in the remainder of array and exchange it with a value in the second position, carry on till you have reached the end of array.
  • Now all the elements have been sorted in ascending order.
 Linear Sorting

Sample Code

// Java program for implementation of Selection Sort 
class SelectionSort 
{ 
    void sort(int arr[]) 
    { 
        int n = arr.length; 
  
        // One by one move boundary of unsorted subarray 
        for (int i = 0; i < n-1; i++) 
        { 
            // Find the minimum element in unsorted array 
            int min_idx = i; 
            for (int j = i+1; j < n; j++) 
                if (arr[j] < arr[min_idx]) 
                    min_idx = j; 
  
            // Swap the found minimum element with the first 
            // element 
            int temp = arr[min_idx]; 
            arr[min_idx] = arr[i]; 
            arr[i] = temp; 
        } 
    } 
  
    // Prints the array 
    void printArray(int arr[]) 
    { 
        int n = arr.length; 
        for (int i=0; i<n; ++i) 
            System.out.print(arr[i]+" "); 
        System.out.println(); 
    } 
  
    // Driver code to test above 
    public static void main(String args[]) 
    { 
        SelectionSort ob = new SelectionSort(); 
        int arr[] = {27,28,45,68,32}; 
        ob.sort(arr); 
        System.out.println("Sorted array"); 
        ob.printArray(arr); 
    } 
} 

Output

Sorted array:
27 28 32 45 68
