Why is this Java operator precedence being ignored here?

Question

The following code prints out \"3\", not \"4\" as you might expect.

public class Foo2 {
    public static void main(String[] args) {
        int a=1, b=2;            


        

Answer 1

The postincrement/decrement operator (a++) returns the value before the increment. The preincrement/decrement (++a) returns the value after the increment.
