异常处理——一种提高软件健壮性的方法

Exception handling is a technique that tests and handles exception events. Unlike the traditional methods that usually deal with exceptions at later design and implementation phases and easily result in many problems, we emphasis that sufficient attention should be paid to software exception handling during the development of the soft-ware requirements definition. By enforcing this policy through all phases of software development, the level of ro-bustness can be improved considerably. In this paper, the concepts of exception handling are firstly introduced, then the methods of exception handling are discussed, all kinds of exception handling methods and tools are also compared.The current problems and future directions are analyzed at the end of the paper.
