I’m creating a simple 2D game in java. I’ve only done this in C++ with the Windows API so far. In java, I’m getting a Graphics object by extending JFrame and calling this.getContentPane().getGraphics(). With this object, I’m drawing everything to the screen, every frame. This raises a few questions:

Backbuffer: I’m not getting any flickering effects, while I’m not using a backbuffer (I’m drawing directly on the Graphics object). Why is this? Does java has a built-in backbuffer or something?
Animations: I’m used to put all animation parts in a single sprite sheet, like in this example:

Now, someone has told me that you can just draw animated .gif’s and java will draw these independent of the game loop. I’ve tried this out and it doesn’t seem to work. Is this true or am I also supposed to use these sprite sheets in java?

Thanks
