Greetings!
It is very common to have numeric iterations like below;
Java 8 has static methods for this common task in IntStream and LongStream.
Note that iterate produces an infinite stream.
It is very common to have numeric iterations like below;
for (int i = 1; i <= 100; i++) {
// do something
}
Java 8 has static methods for this common task in IntStream and LongStream.
IntStream intStream = IntStream.rangeClosed(1, 100);
// Inclusive. Up to 100: 1, 2, ..., 99, 100
IntStream.rangeClosed(1, 100).forEach(System.out::println);
// Exclusive. Up to 99: 1, 2, ..., 98, 99
IntStream.range(1, 100).forEach(System.out::println);
// With Steps: 1, 2, ..., 98, 100
IntStream.iterate(0, i -> i + 2).limit(50).forEach(System.out::println);
Note that iterate produces an infinite stream.
