对于RuntimeException的子类最好也使用异常处理机制。虽然RuntimeException的异常可以不使用try...catch进行处理,但是如果一旦发生异常,则肯定会导致程序中断执行,所以,为了保证程序再出错后依然可以执行,在开发代码时最好使用try...catch的异常处理机制进行处理。 2.User Defined Exception 下面给出一个自定义异常的实例:...

SQL NULL values are represented by Java variables that are not initialized. These variables have a Java null value if they are object types. If an SQL NULL is passed to a Java scalar data type, such as int, then an exception condition is raised. ...
A 'java.security.NoSuchAlgorithmException' exception will be thrown in such circumstances. For compatibility, use the keystore.pkcs12.legacy system property, which will revert the algorithms to use the older, weaker algorithms. There is no value defined for this property.
