语法错误，插入“EnumBody”完成EnumDeclaration [英] Syntax error , insert "EnumBody" to complete EnumDeclaration
问题描述
private; 被放置为类的第一行语法错误，插入EnumBody完成ClassBodyDeclarations （由@ chaitanya10在下面的评论中写下，并且在我的工作空间上由我验证）当我们将鼠标悬停在它上面时，eclipse工具提示中的错误。
我明白有错误。
但是当我将光标悬停在错误上时，我不明白错误信息。这个消息的意思是什么？
为什么它期待 EnumBody ？
以下是截图。
解决方案为了真正的解释，有人需要做语法检查的详细分析，以及Eclipse Java编译器前端的语法错误恢复和报告组件。但是最有可能的解释是，您的异常语法错误使编译器的语法错误恢复代码混淆。
简而言之，它是一个较小的编译器错误）
开发人员很可能会知道这一点，但是没有修复它，因为：
- 它不会经常发生，
- 可能很难做更好的工作，而不会打破其他错误恢复案例，和/或
- 任何更改将会打破许多编译器错误回归测试。
I was in middle of coding and accidentally put the following line of code at the part of class where we declare instance variables. but i checked and it gives the same error anywhere by anywhere i mean : inside a static block, inside constructor, inside any class method. except when private; is put as the first line of the class it gives
Syntax error, insert "EnumBody" to complete ClassBodyDeclarations (as written by @chaitanya10 in comments below and also verified by me on my workspace) error in eclipse tooltip when we hover cursor over it.
I understand there is error.
but I dont understand the error message when i hover cursor over the error. what is the meaning of this message?
why does it expecting EnumBody ?
Below is the screenshot.
解决方案 For a real explanation, someone would need to do a detailed analysis of the syntax checking, and the syntax error recovery and reporting components of the Eclipse Java compiler front end. But the most likely explanation is that your "unusual" syntax error has "confused" the compiler's syntax error recovery code.
In short it is a minor compiler bug (or feature).
It is likely that the developers know about this, but have refrained from fixing it because:
- it doesn't happen often,
- it might be hard to do a better job ... without breaking some other error recovery cases, and / or
- any change would break a number of compiler error regression tests.
