    Selection Sort in Java

    In this example, we'll create a java program to sort the array elements using selection sort.

    In the selection sort algorithm, we look for the lowest element and arrange it to the right location. We swap the current element with the subsequent lowest number.

    Program: 
    
public class Main {  
public static void selectionSort(int[] arr){  
for (int i = 0; i < arr.length - 1; i++)  
{  
int index = i;  
for (int j = i + 1; j < arr.length; j++){  
if (arr[j] < arr[index]){  
index = j;//searching for lowest index  
}  
}  
int smallerNumber = arr[index];   
arr[index] = arr[i];  
arr[i] = smallerNumber;  
}  
}  
public static void main(String a[]){  
int[] arr1 = {9,41,13,2,43,51,58,82,79,49};  
System.out.println("Before Selection Sort");  
for(int i:arr1){  
System.out.print(i+" ");  
}  
System.out.println();  
selectionSort(arr1);//sorting array using selection sort  
System.out.println("After Selection Sort");  
for(int i:arr1){  
System.out.print(i+" ");  
}  
}  
}
    Output:
    Before Selection Sort
    9 41 13 2 43 51 58 82 79 49
    After Selection Sort
    2 9 13 41 43 49 51 58 79 82
