Simple way to repeat a string

Question

I\'m looking for a simple commons method or operator that allows me to repeat some string n times. I know I could write this using a for loop, but I wish to avoid f

Answer 1

If you only know the length of the output string (and it may be not divisible by the length of the input string), then use this method:

static String repeat(String s, int length) {
    return s.length() >= length ? s.substring(0, length) : repeat(s + s, length);
}

Usage demo:

for (int i = 0; i < 50; i++)
    System.out.println(repeat("_/‾\\", i));

Don't use with empty s and length > 0, since it's impossible to get the desired result in this case.
