Question

is there a nice way for creating a string initialized with a number of characters given an int (counter) and the character to set.
Simply put I would like a method that returns “#,#,#,#,#” when passed 5 and # as parameter.

Any ideas?

Using the StringUtils utility in the Apache Commons lang library:

String myString = StringUtils.repeat("#", ",", 5);

If you only want the characters (and not the comma separators), it is just:

String myString = StringUtils.repeat("#", 5);
