Print character multiple times [duplicate]

Answer 1

If you can use external libraries, StringUtils.repeat sounds perfect for you:

int s = 5;
System.out.println(StringUtils.repeat('_', s));

EDIT:
To answer the question in the comments - StringUtils.repeat takes two parameters - the char you want to repeat and the number of times you want it, and returns a String composed of that repetition. So, in the example above, it will return a string of five underscores, _____.
