How to create String of length consisting of same character repeated multiple times? [duplicate]

Question

If i want a String s which would consist of n instances of character A, can this be done cleaner in Java other then

public static String stringOfSize(int size, char ch) {
    StringBuilder s = new StringBuilder();
    while (size-- > 0) {
        s.append(ch);
    }
    return s.toString();
}

Can we do better? Just wondering.

Answer 1

Nothing wrong with this code at all... But maybe you can use Arrays.fill():

public static String stringOfSize(int size, char ch)
{
    final char[] array = new char[size];
    Arrays.fill(array, ch);
    return new String(array);
}

Answer 2

You could do the following:

return StringUtils.repeat(ch, size);

Note: StringUtils is not built-in to the JDK - see http://commons.apache.org/proper/commons-lang/
