Hi Friend,

Try this:

import java.io.*;
import java.util.*;
class bubble {
    public static void main(String args[]) throws Exception{
        int a[]=new int[10];
        BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
        System.out.println("Enter 10 no. to sort");
        for(int i=0;i<a.length;i++){
            a[i]=Integer.parseInt(br.readLine());
        }
        Arrays.sort(a);
        System.out.println("Sorted Array: ");
        for(int i=0;i<a.length;i++){
            System.out.println(a[i]);
        }
    }
}

Thanks
