Answer 1

As correctly said in above answers, you've experienced overflow, however with below java 8 code snippet you can print series.

Stream.iterate(new BigInteger[] {BigInteger.ZERO, BigInteger.ONE}, t -> new BigInteger[] {t[1], t[0].add(t[1])})
        .limit(100)
        .map(t -> t[0])
        .forEach(System.out::println);
