Scope: Java
Q:
if you have three class A, B, and C all have the same method doShow();
We only know that all inherit from Class Object (like all other classes do).
Is it possible to have a public function that takes in an Class Object that
may belong
to A, B, or C, and call doShow()?
Something conception like:
public void show(Object o) {
o.doShow();
}
Of course the above code won't compile. One way to hack it is to use
"InstanceOf" (one of the answer) but it's a unclean hack.
Anyone has any better ideas? I thought about going from Object.getClass(),
but it does
not seem to be the way.
