推荐答案

引用 paint（）的文档方法

此方法实际上将绘画工作委托给三个受保护的方法：paintComponent，paintBorder和paintChildren。
...
只想专门化UI（外观）委托的paint方法的子类应该覆盖paintComponent。

This method actually delegates the work of painting to three protected methods: paintComponent, paintBorder, and paintChildren. ... A subclass that just wants to specialize the UI (look and feel) delegate's paint method should just override paintComponent.

看起来 paint（）方法实际上绘制了组件，包括边框和子项。如果您只想自定义除边框和子项之外的组件外观，则使用 paintComponent（）。

It looks like the paint() method actually draws the component, including the border and children. If you only want to customize the component's appearance excluding the border and children, you use paintComponent().
