Why the output of this code is different?

Question

int a[] = {120, 50, 016};

for(int P : a)
    System.out.print(P+" ");

I expect the output of above code is 120 50 16, but the actual output is 120 50 14.

The leading 0 stands for octal numeral system: In this your 016 = 1 * (8^1) + 6 * (8^0) = 14 — tobsob, Aug 15 '19 at 08:57
have a look at Java Language Specification [3.10. Literals](https://docs.oracle.com/javase/specs/jls/se12/html/jls-3.html#jls-3.10) - some more *strange* (good to know) facts, like underscore in literal numbers — user85421, Aug 15 '19 at 09:24

That is because '016' is behaving as and its octal value 14.

It is octal base 8 because you have a 0 in front.
