prefix and postfix increments while comparing variables
- by miatech
could someone explain why this code output is
not equals
not equals 2
in the first if statement it seems that a = 0 b/c is a postfix increment; therefore a will not increase untile next line; however, the two a's are not equal why? and in the second if when I run the debugger the value of a is 2, but the test is false, why?
public static void main (String[] args)
{
int a = 0;
if (a++ == a++) {
System.out.println("equals");
} else {
System.out.println("not equals");
}
if (++a == 2) {
System.out.println("equals 2");
} else {
System.out.println("not equals 2");
}
}
