What is the difference between int++ and ++int?

In Java, what is ++int? What does it do? What does it mean?

(Sorry, but I didn't ask the question correctly last time.)

It's exactly the same as the C++ answer you got in your other question.. — Brendan Long, Mar 29 '12 at 00:55
@Brendan, mostly true, but any differences are fully [elaborated here](http://stackoverflow.com/a/6457294/189950). — Kirk Woll, Mar 29 '12 at 00:58

a = 5; b = ++a; // a = 6, b = 6
a = 5; b = a++; // a = 6, b = 5

Other way around: `a` is incremented after the assigment. `b` uses the old value of `a` – Sionide21 Apr 09 '12 at 12:09

int a=1;
System.out.println(a++);

prints "1"

int a=1;
System.out.println(++a);

prints "2"

Or maybe i don't understand your question.

++int increments int by 1 before and int++ increments by one after
