我不知道如何进行如下布局：
原谅我写的很烂。我的平板电脑无处可寻，所以我不得不使用鼠标。无论如何，我只是想知道如何用我的井字游戏正确地做类似的事情。
我已经得到了应该在的网格，但我这辈子也无法在屏幕上获得标题。我也想知道如何做一个简单的纯色条，如图所示。我也尝试过，但它不会总是出现。有时它会闪烁，有时它会闪烁然后消失，或者根本不出现。
我会说这可能与我设置布局的方式有关，但我不知道如何做网格。哦！我还想，如果我弄清楚整个面板添加到框架的事情出了什么问题，我可能会弄清楚为什么当您尝试单击已占用的按钮时应该显示的红色错误文本没有出现。我很确定这是同样的问题。
这是我的代码：

JFrame frame = new JFrame ("Tic-Tac-Toe");

//non-blank button
JPanel titlestrip = new JPanel (); //the strip behind the title
JPanel bgpanel = new JPanel (); //the background panel that fills up the window
JPanel bgpanel2 = new JPanel (); //second bg panel with no layout
JPanel buttonpanel = new JPanel(); //the panel that holds the nine buttons
