What is the Java equivalent of a C# Graphics object? (more details included)

In a C# Windows form, there is a Graphics object which is used to draw images and shapes directly to the form. What开发者_开发知识库 is the equivalent in Java?

In case my question isn't clear enough, I wish to draw to a form in Java like I would in C#. I am aware of Applets and JApplets, but I want to do this in an actual form and not in a browser.

It's also Graphics in Java. (Surprise!)

Sometimes you need to cast the object to Graphics2D for more advanced graphics manipulations.
