37 提示:Got an exception - java.lang.RuntimeException: Unable toget class information for @throws tag *whatever*. 网上参考解决方法:选中CheckSytle的JavaDoc --> Method JavaDoc -->logLoadErrors。如果是CheckStyle自己加载时出错的,打个Log就可以了,不要整出Errors吓人。(这个问题没遇到过,所以没做过尝...

Caught exception must be handled, re-thrown, or wrapped, exceptions must NOT been swallowed Unchecked exceptions can be used when errors cannot be handled by the application; for example, DAO runtime exceptions are handled using spring AOP ...
The Java language [2] and virtual machine [3] provide many features to mitigate common programming mistakes. The language is type-safe, and the runtime provides automatic memory management and bounds-checking on arrays. Java programs and libraries check for illegal state at the earliest ...

异常类名必须以Exception结尾。测试用例名称应以要测试的类名开头,以Test结尾。 7.【强制】括号是Array类型的一部分。定义可以是:String[] args; 反例: 字符串参数[]; 8.【强制】在定义布尔变量时不要添加'is'作为前缀,因为这可能会导致某些Java框架中的序列化异常。
8.[Mandatory]Do not add 'is' as prefix while defining Boolean variable, since it may cause a serialization exception in some Java frameworks. Counter example:boolean isSuccess;The method name will beisSuccess()and then RPC framework will deduce the variable name as 'success', resulting in a ...
