JAVA五子棋中如何实现重新开始和悔棋的功能

一般来说是不应该像你这样写的，应该是把要画的步骤写在组件的被覆写的paintComponent函数里，然后在你响应事件的函数里直接掉用该组件的repaint()函数即可。repaint函数是会去掉该组件的paintComponent()函数的。至于你这么写为啥不行，这个我也不清楚，据我猜测，repaint函数要做的事情是刷新组件，并且重新去画一遍，不过这个步骤不一定是立即完成，可能有延迟。总之在你画那些棋子之后，它又干了一些事情，导致你画的棋子没了（但这不会影响到它自己想去画的东西，即paintComponent()函数里的东西），另外不要忘了，覆写paintComponent时，第一行要写，super.paintComponent(g)，这是去画它原来有的东西（比如加上去的按钮，文本框之类的东西）
