C has typed pointers.
How are they really typed? In Java, I'll get a runtime exception
when I mis-cast... In C, IIRC, I get long hours of debugging...
Cast? Why do you want to do that?
I'll take this as a straight question, although I can actually hear
you saying it and I'm suspicious :)
I actually never understood why I do it other than for readability,
because I do think that the runtime can figure it out.
There's a legitimate use when upcasting to a superclass.
public class Bar {
}
public class Foo extends Bar {
}
Foo f = new Foo();
Bar b = (Bar) foo;
