Hi,


I ve the following problem:

I have:
     3 Classes: "A", "B" and "C"
     1 Method: "processObject(Object obj)"

"obj" may be from type "A", "B" or "C" .


processObject(Object obj)
{
    if (obj from type A)
        obj.writeA();
    else
    {
        if (obj from type B)
            obj.writeB();
        else
        {
            if (obj from type C)
                obj.writeB();
            else
            {
                extra processing for obj;
            }
        }
    }
}


How can I use the specific methods (writeA(), writeB(), writeC()) ?
How should I change the code of "processObject(Object obj)"?


Thank you
H. Jrad :-)
