我正在编写一个java项目，突然之间，eclipse报告说我的代码存在问题。它特定于一个文件，但是其他文件也失败了，因为它们使用了所讨论的类中的一些函数，它们似乎找不到它们的功能。我已经尝试了几乎所有我能想到的东西来消除这个错误。
具体来说，第一个错误是：
Syntax error, insert "}" to complete ClassBody
只是为了说明，这是代码：

只是我或其他人是否收到此错误？
欢迎任何有关如何修复它的建议！

好。我终于设法解决了这个错误。
正如在顶部帖子中的评论中所提到的，如果我清除了构造函数，我可以将其编译。一旦我得到它编译我慢慢地将代码逐行粘贴到我的项目中。我省略了ActionListeners，它编译得很好。在此之后，我慢慢地逐个导入ActionListener方法，我发现了一行导致错误。这是一行：
App.getSharedResources().changeRow(index, newRow); //line 106
这个方法还没有实现，它在上面说明的过程之后给了我一个错误。我可以创建该方法，我的其余代码现在按预期编译。这是一个非常奇怪的错误。

过去某个时候我也遇到过类似的问题，请你试着从“问题”中删除错误。之后查看并执行一个干净的项目，看它是否消失。
如果没有帮助尝试：查看工作区目录中eclipse创建的.log文件。这可能会为如何解决这个问题提供线索。
