If an object of type componet is coming into a method, what is the best
way to detemine it's type, such as checking if it's a JInternalFrame, or
JPanel?

Thanks.

You mean, if you have an reference, of compile-time type Component, how do you find out the run-time type of the object to which it points?

Usually, you would use the "instanceof" operator.

You can also use reflection:

Of course, this may be of only limited use depending what you need to do with this information once you have it.
