button.addMouseListener(new MouseAdapter(){               public void mouseClicked(MouseEvent e){
                MessageDialog.openInformation(null,"","Hello world");
            }
        });

这里有问题吗,提示说"类型 Control 中的方法 addMouseListener（MouseListener）对于参数（new
MouseAdapter(){}）不适用"什么意思啊?

可能是Button不能添加MouseEvent的事件的监听器吧
换成 Button.addActionListener试试
