Final variable casting in Java

final double integer = 20/100;

If i was to print integer, I would get 0 rather than 0.2

double integer1 = 20/100;

If I was to print integer1, I would get 0.2

final double integer3 = 200/100;

If I was to print integer3 out, I would get 2.0.

Can anyone explain why I get 0 for the first print statement and not 0.2 since its a double, and why it works for the third statement, where I got 2.0 as the result.

Try `20.0` in your first expression. – PM 77-1 Nov 29 '15 at 00:08
`double integer1 = 20/100;` returns `0.0` for me (not `0.2`). – Mick Mnemonic Nov 29 '15 at 00:09
