String display without any loops

[yuva rani]

how to display a string 'n' number of times without using any loops. here 'n' is user entered integer number.

You could try recurssion.

If you do a search of the ranch, I am sure there are plenty of topics mentioning recurssion, and plenty on the web in general.

Good idea, Gavin.

And welcome to JavaRanch, Yuva Rani.

Yuva,

Here is a recursive example that might help you for your problem. Keep in mind this is just one possible solution (a loop is a much better idea though since recursion creates a bunch of calls on the stack and can often be harder to understand).

public void printStringNTimes(int n, String s) {
  if ( n > 0 ) {
      System.out.println(s);
      printStringNTimes(n-1);
  }
}

Hope this helps,
Jeff

I guess its a matter of preference, but I normally find recursion easier to understand than loops.

Jeff i think you missed one small thing in your code

 printStringNTimes(n-1,s);

instead of

 printStringNTimes(n-1);

Thank you for answering my question!!

Jeff - basically, you just did this guy's homework for him. At JavaRanch we ask LetThemDoTheirOwnHomework.

By all means give hints (e.g. "you could consider recursion"), but not fully -worked answers.
