generate(Supplier)

The Stream<T> generate(Supplier<T> supplier) static method of the Stream interface creates an infinite stream, where each element is generated by the provided Supplier<T> function. Here are two examples:

Stream.generate(() -> 1).limit(5)        .forEach(System.out::print);       //prints: 11111Stream.generate(() -> new Random().nextDouble()).limit(5)        .forEach(System.out::println);     //prints: 0.38575117472619247                                           //        0.5055765386778835                                           //        0.6528038976983277                                           //        0.4422354489467244                                           //        0.06770955839148762

Since the stream is infinite, we have added a limit() operation.
