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.)

Solution 1

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

Solution 2

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.

Solution 3

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

It's exactly the same as the C++ answer you got in your other question..

@Brendan, mostly true, but any differences are fully elaborated here.

Other way around: a is incremented after the assigment. b uses the old value of a
