Can I get Class<T> from Class<T[]>?
public static <T> void doSometing(final Class<T[]> arrayType) {
final Class<T> elementType; // = @@?
}
Or, can I get Class<T[]> from Class<T>?

You can use Class.getComponentType(), although there's no way for that method to give you generic type safety, so you'll need to do an unchecked cast to get a Class<T>:
public static <T> void doSomething(final Class<T[]> arrayType) {
@SuppressWarnings("unchecked")
final Class<T> componentType = (Class<T>)arrayType.getComponentType();
//etc.
}
For the reverse, see this question: Obtaining the array Class of a component type

@JinKwon Sorry I didn't see that sooner. Looks like it's been answered pretty well.
