Java 7 introduced the multi-catch feature, allowing you to handle multiple exception types in a single catch block. This can lead to more concise and readable code, especially when you want to handle different exceptions in the same way. Here's a simple example: try{// code that may throw...
If a catch block handles multiple exceptions, you can separate them using a pipe (|) and in this case, exception parameter (ex) is final, so you can’t change it. The byte code generated by this feature is smaller and reduce code redundancy. Another improvement is done in Compiler analys...

Java 只支持单继承,不支持多继承 单继承就是一个类只能有一个父类;多继承就是一个类可以有多个父类。 子类可以继承父类所有的成员变量和成员方法,但子类永远无法继承父类的构造器(Constructor)。在子类构造方法中可以使用语句 Super(参数列表)调用父类的构造方法。
