使用Flow Layout时无法更改JLabel的位置，也无法一次打印JLabel三次

标签： java jframe jlabel flowlayout

我正在尝试在paint方法中更改名为label11的JLabel的位置。我将它添加到我在Sudoku中扩展的JFrame中，它只能打印一次，而不是三次。当我运行它时，它会进入顶部中间，并打印三次。如何将JLabel的位置设置为（x，y）坐标，并且只打印一次。此外，如果你取消注释所有打印出矩形的线条，那么它应该制作一个数独板，每个盒子里面会有一个数字。我的代码如下。任何帮助表示赞赏。谢谢！

使用FlowLayout时，您无法直接设置位置。

查看此LayoutManagers列表，了解您的需求。 GridLayout可能对你有好处。
