Iteration without loop

Hi,

Is there any way I can have a line of code iterate a number of times set by the user without having a while loop or any other control statements?

Thanks!

import java.util.*;
class RepeatString 
{
    public static String repeat(String str, int times){
   return new String(new char[times]).replace("\0", str);
}

    public static void main(String[] args) 
    {
        Scanner input=new Scanner(System.in);
        System.out.println("Enter no. of times: ");
        int no=input.nextInt();
        String st="Hello World";
        System.out.println(repeat(st+"\n", no));

    }
}
