Java

Works with: Java version 1.5+

There's no function or operator to do this in Java, so you have to do it yourself. <lang java5>public static String repeat(String str, int times){

  StringBuilder ret = new StringBuilder(str);
  for(int i = 1;i < times;i++) ret.append(str);
  return ret.toString();

}

public static void main(String[] args){

 System.out.println(repeat("ha", 5));

}</lang>

JavaScript

This solution creates an empty array of size n+1 and then joins it using the target string as the delimiter <lang javascript>String.prototype.repeat = function(n) {

   return new Array(1 + parseInt(n, 10)).join(this);

}

alert("ha".repeat(5)); // hahahahaha</lang>

Ruby

<lang ruby>"ha" * 5 # ==> "hahahahaha"</lang>

Tcl

<lang tcl>string repeat ha 5  ;# => hahahahaha</lang>
