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...
For example, when the -ber -helperAPI pdudecoder options are used, the PDU class contains methods to decode a PDU from the BER input: public static PDU decode(InputStream source, BERCoder coder) throws DecodeFailedException; public static PDU decode(java.nio.ByteBuffer source, BERCoder coder)...
非运行时异常强制程序员处理这些可能出现的问题,增强了程序的健壮性。 运行时异常:这类异常包括运行时异常(RuntimeException)和错误(Error)。运行时异常由程序错误导致,如空指针访问(NullPointerException)、数组越界(ArrayIndexOutOfBoundsException)等。运行时异常是不需要在编译时强制捕获或声明的。
ERR07-J Do not throw RuntimeException, Exception, or Throwable. ERR08-J Do not catch NullPointerException or any of its ancestors. ERR09-J Do not allow untrusted code to terminate the JVM. VNA00-J Ensure visibility when accessing shared primitive variables. VNA01-J Ensure visibility ...

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 ...

原则上禁止执行系统命令,可以考虑使用JNI或者API接口等方式调用外部程序;因此,建议禁用java.lang.Runtime#exec、java.lang.ProcessBuilder#start类; 如必须执行系统命令,且必须拼接系统命令,那么务必严格校验传入输入的合法性,例如,调用ping命令检测网络连接时需要传入域名或者IP:ping baidu.com,那么传入的就必须是一个合法...
