post increment

hello frnsss..

i was using the post increment in the while loop like this

int a= 0;
while(a++<8)
{
//body of the loop
}

when this will executes then it first increment the value of a and then do the comparison ..
but when i use the same in switch like this ..

int a=0;
switch(a++)
{
case 1: System.out.print("hello");
break;
default: System.out.print("deflt");
}

when this code executes it executes only default part .. which means it do not increments the value of a in switch..
how this behavior is different in switch and while statements when i use the post increment .. please explain ... this behavior of post increment in these cases ..

Thanks

That's not ok. Post increment first evaluate the variable, then increments.

So, if you have

int a=0

System.out .... (a++) //Print 0
System.out .... (++a) //Print 2
