    Default 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

    Default Re: post increment

    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
