我应该使用什么布局来使 Java 有效？
What layout should I use to make this work for Java?
这是我想要的最终结果...
我正在尝试为此使用 GridBagLayout，但不确定它是否是正确的选择，因为它到处都是。我知道我不应该在一个构造函数中编写所有代码，但这是我目前所拥有的...

它有点难看，你可以忽略我的大部分评论我一直在努力解决它。我使用的是不同的布局。
使用 GridBagLayout，或使用 netbeans，这对您来说会很容易，其他选项使用 GridLayout(2,1)
其中2个面板
面板 1 的网格布局为 1,2，您首先列出，其他 pnael 的网格布局为 2,1 第一行是您的第二个列表，第二行将是按钮，最终将订单信息放在您的第二行基地布局。
已编辑：我继续创建比萨店 GUI。
我结合使用了 BorderLayouts 和 GridBagLayouts。
我将代码组合在一起以使其更易于理解。将代码分组并不意味着将所有 JCheckBox 初始化放在一起。对代码进行分组意味着构成 JPanel 的所有元素都在那里，彼此相邻。这样，您就不必遍历所有代码来查找定义 JRadioButton rbMedium 的行。
我为每个 Swing 组件使用了单独的 GridBagConstraints 以使我更容易调试 GUI。
我已将动作侦听器留给您编写代码。
