你这段代码的语法，必须j2sdk1.5以上才支持，我怀疑你用的是1.4版本（cmd窗口下，java -fullversion可以看版本）。两种解决方法：
1）你更换j2sdk.
2）把这段代码修改以下：
for(int i=0;i<infos.length;i++)
makeButton(infos[i].getName(),infos[i].getClassName());
JButtton button = new JButton(name);
add(buttton);
上面两行有错误JButton，你多写了个t;变量你定义的是button,下面用的时候也多写了个t.都是拼写错误。该了就可以了
JButton button = new JButton(name);
add(button);
PlafPanel panel = new PlafPanel();
//add(panel); //错误
getContentPane.add(panel);
