Can one initialise a java String with a single repeated character to a specific length.

Question

I'd like to create a function that has the following signature:

public String createString(int length, char ch)

It should return a string of repeating characters of the specified length.

For example if length is 5 and ch is 'p' the return value should be

ppppp

Is there a way to do this without looping until it is the required length?
And without any externally defined constants?

Answer 1

char[] chars = new char[len];
Arrays.fill(chars, ch);
String s = new String(chars);

Answer 2

StringUtils.repeat(str, count) from apache commons-lang

Answer 3

You can use Arrays#fill() for this.

public String createString(int length, char ch) {
    char[] chars = new char[length];
    Arrays.fill(chars, ch);
    return new String(chars);
}
