Below is the sample java source code on sorting numbers using selection sort. Selection Sort in java is much prepared by the programmers when it comes on sorting. Here, I will present to you on how the selection sort works.

How Selection Sort works in Java?

Assuming the user entered 6 numbers which are:

4 5 1 3 2 6

The program will sort it in an ascending order using selection sort. The program will simply compare the first number which is 4 to the second number, third number and so on, and then sort. See below on how it works.

From the entered numbers 4 5 1 3 2 6

Sorted To:

5 1 3 2 4 6

1 3 2 4 5 6

1 2 3 4 5 6 //sorting ends here and this will be output to the screen.

Sorting in selection sort is pretty fast than bubble sort. But If you are interested on comparing other methods of sorting like bubble sort , you can visit the link below.

Java Source Code: How to Sort Numbers using Selection Sort

//java class

public class SelectionSort
{

     public void SelectionSort(int[] arr){
     for(int i=0; i<arr.length; i++)
     {
        for(int j=i+1; j<arr.length; j++)
        {
            if(arr[i] > arr[j] )
            {
                int temp = arr[j];
                arr[j] = arr[i];
                arr[i] = temp;
            }
        }
     }

     for(int i=0; i<arr.length; i++)
     {
         System.out.print(arr[i] + " ");
     }
}

//main class


import java.util.Scanner;

public class Main
{

    public static void main(String[] args)
    {

        Scanner input = new Scanner(System.in);

        System.out.print("Enter the size of the array: ");
        int n = input.nextInt();
        int[] x = new int[n];

        System.out.print("Enter "+ n +" numbers: ");
        for(int i=0; i<n; i++)
        {
            x[i] = input.nextInt();
        }

        SelectionSort access = new  SelectionSort();
        System.out.print("The Sorted numbers: ");
        access.SelectionSort(x);
    }

}
