Java Program for Selection Sort

After Bubble Sort sorting algorithm in previous tutorial, this time i am covering the Selection sort program code in Java with the output.
The selection sort technique is a combination of searching the smallest or largest element and after that sort the elements in ascending or descending order . During each pass, the unsorted element with the smallest or largest value is moved to its proper position in the array. The idea of selection sort is very simple: we repeatedly find the next largest or smallest element in the array and move it to its final position in the sorted array.

Selection Sort Java Program

 

public class SelectionSort {

   public static void main(String args[]) {

     int[] x =
     {547, 3, 523, 378, 133, 1714, 14, 23, 310};

     System.out.println("Unsorted list: ");
     display(x);

     selectionSort(x);
     System.out.println("Sorted list: ");
     display(x);
   }

   private static void selectionSort(int x[]) {

     int n = x.length;
     int i, indx, j, large;

     large = x[0];
     indx = 0;

     for (i=n-1; i>0; i--) {

       large = x[0];
       indx = 0;

       for (j=1; j<=i; j++)
         if (x[j]>large) {
           large = x[j];
           indx = j;
         }
       x[indx] = x[i];
       x[i] = large;
     }

   }
   private static void display(int x[]) {
     for (int i=0; i<x.length; i++)
       System.out.print(x[i] + " ");
     System.out.println("\n");
   }
}
