--------------------配置: <默认>--------------------
G:\learn space\Java\两个窗体\A.java:27: A.Addbutton.MyListener1 不是抽象的，并且未覆盖 java.awt.event.ActionListener 中的抽象方法 actionPerformed(java.awt.event.ActionEvent)
        private class MyListener1 implements ActionListener
                ^
G:\learn space\Java\两个窗体\A.java:35: A.Addbutton.MyListener2 不是抽象的，并且未覆盖 java.awt.event.ActionListener 中的抽象方法 actionPerformed(java.awt.event.ActionEvent)
        private class MyListener2 implements ActionListener
                ^
G:\learn space\Java\两个窗体\A.java:43: A.Addbutton.MyListener3 不是抽象的，并且未覆盖 java.awt.event.ActionListener 中的抽象方法 actionPerformed(java.awt.event.ActionEvent)
        private class MyListener3 implements ActionListener
                ^
G:\learn space\Java\两个窗体\A.java:56: title 在 java.awt.Frame 中不是公共的；无法从外部软件包中对其进行访问
                this.setTitle(title);//super(title);
                              ^
4 错误
处理已完成

前三个是ActionListener接口actionPerformed方法没有实现(空实现也是实现)
最后一个是拼写错误 把title 拼成tilte
