public class StringSetBuggy
extends java.util.AbstractSet<java.lang.String>

A simple implementation of a set of strings. It does not allow null strings in the set. The purpose of this class is just to be an example implementation of Set, which we can run tests on, insert errors into, measure the coverage of the tests etc. This class has an intentional bug: the equals method contains an off-by-one error.
