本文介绍了一个组件的重绘方法，该方法确保轻量级组件尽快调用其paint方法，而其他组件则调用其update方法。文章还提到了AWT和Swing的绘画机制以及如何编写高效的绘画代码。
repaint
public void repaint()Repaints this component.
If this component is a lightweight component, this method causes a call to this component's paint method as soon as possible. Otherwise, this method causes a call to this component's update method as soon as possible.
Note: For more information on the paint mechanisms utilitized by AWT and Swing, including information on how to write the most efficient painting code, see Painting in AWT and Swing.
Since:
JDK1.0
