What is the output?

Question

int i = 5;
System.out.println(i++);
System.out.println(++i);

Answer 1

This is Java. Why it has a c++ tag?
the output is :
// 5
// 7

Answer 2

i++ will perform the increment AFTERWARDS, so you get 5 on that one and move along with its value changed to 6.

++i performs the increment BEFORE, so its value becomes 7 and then is printed
