6 errors

Answer 1

In the case of the first 5 errors, it looks like you might have a class or variable named Class somewhere in your code that is covering up java.lang.Class, which is what you want. Try changing those to java.lang.Class.forName("..."); and see what you get.

Without more information, you're on your own for the 6th error. You haven't given us any context. Do you have an actual variable named Category anywhere, or are you missing something?

Answer 2

Adding to what @T. Yates says, it is a bad style to declare classes with names that are the same as widely used Java classes. It results in "mysterious" compilation errors, and in other people misreading your code.

I'd avoid reusing any names declared in (at least) java.lang, java.io, java.util and java.net, along with the common classes used in AWT, Swing, JDBC and a few other subsystems.
