Java Eclipse中出现了很多错误

我不知道在这段代码中哪里可以找到错误的根源，希望有人能帮上忙。错误粘贴在源文件之后。直到2秒钟前，我做了一个更改，使eclipse想要终止当前正在运行的应用程序时，这一切都非常好

你少了一个括号

appFrame.addWindowListener(new WindowAdapter() {
            public void windowClosing(WindowEvent event) {
                //save file
            **}** //Bracket here
});

我自己无法回答，但我能解决它<代码>我忘了一个括号：appFrame.addWindowListener（新WindowAdapter（）{public void windowClosing（WindowEvent事件）{//save file}}）
