postfix ++ operator (exam question for SCJP)
- Thread starter engdict
- Start date
java does not handle prefix and postfix the same way that other lang's do. in java, prefix will change the value of the variable but postfix will not.
int i = 2;
i = i++;
System.out.println("i: " + i);
will give the output of 3.
hope this helps.

both prefix and postfix will increase the variable by one.
however, whether the "++" is near of far from the "=" acts differently.
j=i++ meane j=i
j=++i means j=(i+1)
in other words, if "++" is near "=", then it counts. otherwise, it does not affect the initialization value of "j".
