range(), rangeClosed()

The range(lower, upper) method generates all the values sequentially, starting from the lower value and ending with the value just before upper:

IntStream.range(1, 3).forEach(System.out::print);  //prints: 12LongStream.range(1, 3).forEach(System.out::print);  //prints: 12

The rangeClosed(lower, upper) method generates all the values sequentially, starting from the lower value and ending with the upper value:

IntStream.rangeClosed(1, 3).forEach(System.out::print);  //prints: 123LongStream.rangeClosed(1, 3).forEach(System.out::print);  //prints: 123
