Question

basic casting should be

MyClass mc = (MyClass)aClass

that is easy

but based on my program, I don’t know the class name until runtime.

for example, the class name could be interp_0, interp_1, interp_2, interp_3 …….#;

Is there anyway in java that I could use to cast it?

For now All I got is

Class afterCast = Class.forName(“Interp_” + countState);

but what I want is

(“Interp_” + countState) afterCast

, not

Class afterCast

.

Thanks for all of you who help me. It is so quick than I expected.

Answer 1

I would suggest using an interface implemented by all these classes which contains the methods you need. You can then cast to this interface. I don’t see why this should be done different because you know which methods you expect at those objects which is an interface actually.
