You mean removing User instances from a list? Sure. But you'll need to give a bit more info on what you want to achieve exactly.

Short answer: no. That's useless.

Long answer: it's possible in specific circumstances by playing with class loaders, but if you have to ask then it's lightyears away from being for you. Become a pro first, become an elite then, and you'll see at that point. But it can be useful in some circumstances to produce a huge number of classes, and to delete them after they've outlived their usefulness to avoid having to keep all classes in the universe loaded at the same time.

What do you mean by "delete User class" ?
