Just as a note, I've been thinking about adding a `repeat(String src, int count)` method to AbstractStringBuffer for quite some. I've held off because I would add a `fillWith(T[] dst, T[] src, int start, int end)` methods to `java.util.Arrays` first. I think both sets of methods would be generally useful based on use patterns in the JDK but for time and motivation. ------------- PR: https://git.openjdk.org/jdk/pull/11939
