What is the difference between anyMatch(), allMatch(), and noneMatch() in the Stream API?

All three are short-circuiting terminal operations that take a Predicate and return a boolean: anyMatch() returns true if AT LEAST ONE element satisfies it, allMatch() returns true only if EVERY element satisfies it, and noneMatch() returns true if NO element satisfies it. Being short-circuiting means they stop processing the stream the instant the answer is determined, rather than always scanning every element.
