Selection sort program using lowest element in java

 // Selection sort by using lowest element of the given array.

import java.util.Scanner;

import java.util.Arrays;

class SelectionSort2

{

public static void main(String args[])

{

Scanner s=new Scanner(System.in);

}

private void sort(int arr[])

{
