Write a method named repl that accepts a String and a number of repetitions as parameters and returns the String concatenated that many times. For example, the call repl("hello", 3) returns "hellohellohello". If the number of repetitions is 0 or less, an empty string is returned.

--------Code--------

public String repl(String phrase, int num)
{
int i;
String what = "";


for(i = num-(num-1); i <= num; i++)
{
   what += phrase;
}
return what;
}
