请教，什么情况，要让你实现双缓存呢？

建议先看看BufferedImage类，或是Orelly的Java 2D Graphics书

you must find where you use this section.
After the show of the panel, the graphic object will be initialized and then you can use it. You had better use a function to check whether it is null, then to something
Another tip, you can put your code into the paint(graphics..) something like it.

你指doubleBuffer吧，为了解决动画频闪的一种方法。
