Answer 1

我想的  定义一个顶级容器  和2个面板。  
把第一个面板放在JFrame 的North ，第二个面板放在Center 然后把一个标签放在第一个面板的正中间Center处。   
把剩下的一堆标签组件按GridLayout 放在第2个面板 8行3列

Answer 2

改了下可以运行

Answer 3

panel2.add(new JScrollPane(panel2));没办法把自己设置在自己的容器中。你查看下这边代码是不是有误。

Answer 4

panel2.add(new JScrollPane(panel1));//你加了自己了
Container c=this.getContentPane();//少个t

Answer 5

        this.add(panel1,"North");
        this.add(panel1,"Center");
改成
        this.add(panel1,"North");
        this.add(panel2,"Center");
