java - Eclipse 中出现很多错误

Question

我不知道在哪里可以查明此代码中的错误根源，希望有人可以提供帮助。错误粘贴在源代码之后。它真的很好，直到大约 2 秒前，当我做了一个更改，使得 Eclipse 想要终止当前正在运行的应用程序。

Answer 1

你缺少一个括号。

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