What is the difference between i++ & ++i in Java?

10 Feb

They both increment the number. ++i is equivalent to i = i + 1.

i++ and ++i are very similar but not exactly the same. Both increment the number, but ++i increments the number before the current expression is evaluted, whereas i++ increments the number after the expression is evaluated.

int i = 3;
int a = i++; //a = 3, i = 4
int b = ++a; //b = 4, a = 4
