Hi Friend,

Try the following code:

import java.util.*;
public class StringArraySelectionSort {

    public static void main(String[] args)throws Exception{
    Scanner input=new Scanner(System.in);
    System.out.println("Enter number or char");
    char[] array = new char[5];
    for(int i=0;i<5;i++){
        char ch=input.next().charAt(0);
        array[i]=ch;
    }
    selectionSort(array);
    for(int i = 0; i < array.length; i++){
    System.out.print(array[i]+" ");
     }
    }
    static char[] selectionSort(char[] array)
    {
        for (int i = 1; i < array.length; i++) {
            int s = i-1;
            for (int j = i; j < array.length; j++) {
                if (Character.toString(array[j]).compareTo(Character.toString(array[s])) < 0) {
                    s = j;
                }
            }
            char temp = array[i-1];
            array[i-1] = array[s];
            array[s] = temp;

        }
        return array;
    }
}

Thanks
