Difference in output

[Phillipe Rodrigues]

Why i am getting different outputs for the below programs?

Program1:

class Test 
{
public static void main(String[] args) 
{
int a =5;
System.out.println(a++);
}
}

Output:
---------- RUN ----------
5

Output completed (0 sec consumed) - Normal Termination

----------------------------------------------------------------------
Program 2:

class Test 
{
public static void main(String[] args) 
{
int a =5;
a++;
System.out.println(a);
}
}

Output:
---------- RUN ----------
6

Output completed (0 sec consumed) - Normal Termination

You're using the postfix increment operator. That returns the old value before incrementing. The prefix increment operator (++a) will return the new increased value.
