while statement program

Problem: Create program that ask the user to input "How many hello world you want to print" and the output show number and hello world.

import java.util.Scanner;

public class helloworld
{
public static void main(String args[])
{
    Scanner input=new Scanner(System.in);
    int num;
    int start=1;
  System.out.print("How hello world you want to display");
  num=input.nextInt();

  while(start<= num)
  {
     System.out.println(start + ".Hello");
    start++;
  }

}
}
