继承(Inheritance)是Java的重要特性之一,使Java能够很方便的面对对象编程(OOP)。继承允许一个类继承其他类的特性。继承会涉及两个关键词(keyword)“extends”和“implements”。 extends AI检测代码解析 class A extends B {...} 1. 在Java中,extends表明正在定义的这个A类是利用继承,从基类B中派生的。所以extends...
multiple inheritance, Google the "dreaded diamond". Java 8 adds default and static methods to interfaces which have traditionally been Java's answer to multiple inheritance. These bring it closer to C++ multiple inheritance, probably a good thing although I've yet to encounter it much in the ...
接口可以继承接口,不能实现接口;抽象类不可以继承接口,但可以实现接口。详见:http://stackoverflow.com/questions/22498245/one-uncertainty-on-multiple-inheritance-in-universal-image-loader 抽象类可以继承实体类。抽象类可以实现(implements)接口,抽象类是否可继承实体类,取决于实体类必须是否有明确的构造函数。 抽象...
Multiple Inheritance: Java doesn’t support multiple inheritance for classes. If a class already extends another class, it cannot extend an abstract class. In such cases, interfaces are more suitable, as Java permits a class to implement multiple interfaces. Versioning Issues: If you add a new ...

implementing Serializable is a serious commitment that should be made with care. Extra caution is warranted if a class is designed for inheritance. For such classes, an intermediate design point between implementing Serializable and prohibiting it in subclasses is toprovide an accessible parameterless co...
