[java] Continuously disposing Graphics

In the examples I've seen, people usually do something like this in their game loop while(running) { myGraphics = (Graphics2D)strategy.getDrawGraphics(); //update sprite states //render the game myGraphics.dispose(); strategy.show(); } My question is: Is it absolutely necessary to get the graphics object anew each time through the loop? It seems kind of repetetive. Any takers? Thanks, Kratz
