ganatantranepal has done it pretty nicely, mine looks messsy, this will take 10 input from user

import java.lang.*;
import java.io.*;

public class jayNepal {
 
 public static void main(String[] args) throws Exception
 {      
                // Read from console
                
                 BufferedReader stdin = new BufferedReader
                  (new InputStreamReader(System.in));

               int[] a=new int[10];
         for(int i=0;i<10;i++)
  {
   System.out.println("Enter value:");
   String input = stdin.readLine();  // from console input example above.
   a[i] = Integer.parseInt( input ); 
  }

               //Sort 
               for(int i=0;i<10;i++)
                 for(int j=i;j<10;j++)
                     {

                System.out.println("Number\tCount");
                System.out.print(a[0]+"\t");
