Iteration with Streams API

StreamExamples.java

// BigDecimal iterator 1 thru 10
Stream.iterate(
                BigDecimal.ONE,
                bigDecimal -> bigDecimal.add(BigDecimal.ONE)
        )
                .limit(10)
                .forEach(System.out::println);

// Integer iterator 1 thru 10
Stream.iterate(1,n -> n + 1).limit(10).forEach(System.out::println);

// Long iterator 1 thru 10
LongStream.iterate(1, n -> n + 1).limit(10).forEach(System.out::println);

// Factorial
final long factorial = LongStream
                .rangeClosed(1, 10)
                .reduce(1, (long a, long b) -> a * b);
