《Effective Java》中关于Ru ntimeException异常的阐述也不是那么尽如人意 Use checked exceptions for recoverable conditions and runtime exceptions for programming errors (Item 58 in 2nd edition) 不过从这句话中我们可以简单引申一下,也就是说,如

Java中定义了两种类型的异常 Checked exceptions:checked exceptions继承自Exception类,调用抛出这种异常API的客户端代码必须要处理导常,否则是不能通过编译的,该异常要么被catch子句捕获要么通过throws子句继续抛出。如:SQLException Unchecked exceptions:RuntimeException也是继承自Exception类,然而所有继承自RuntimeException的异...
Classes that inherit directly or indirectly fromError(serious abnormal situations in JVM, application program should not attempt to deal with)are unchecked, too. Unlike checked exceptions, Java does not examine whether an unchecked exception is caught or declared because they typically can be prevented...
1. What isExceptionin Java? “An exception isan unexpected eventthat occurred during the execution of a program, anddisrupts the normal flow of instructions.” In Java, all errors and exceptions are of type withThrowableclass. When an error occurs within a method, themethod creates an object(...

尽管,这个定义十分简单,但是RuntimeException却是一个非常让人容易混淆的观念,似乎我们所有的异常都是在程序运行的过程中。我《Effective Java》中关于Ru ntimeException异常的阐述也不是那么尽如人意, Use checked exceptions for recoverable conditions and runtime exceptions for programming errors (Item 58 in 2nd...
并不是唯一这么想的人. 既然在这一点上慢慢形成我自己的观点, 我注意到Bruce Eckel, 他是经典的Thinking in Java的作者, 也改变了他的观点. 现在Eckel提倡使用运行时异常, 并且怀疑checked exceptions是否只是一种不成功的试验, 应该从Java中抛弃. 参见http://www.mindview.net/Etc/Discussions/CheckedExceptions....
