JIANG Shu-Juan XU Bao-Wen (Department of Computer Science & Engineering, Southeast University, Nanjing 210096) (School of Computer Science & Technology, China University of Mining & Technology, Xuzhou 221008) (Jiangsu Province Key Laboratory of Computer Information Processing, Soochow University, Suzhou 215006)  
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 software requirements definition. By enforcing this policy through all phases of software development, the level of robustness 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.
