- If a class extends two interfaces that have default methods with the same name and signature, the compile will throw an exception. - But if the subclass overrides the duplicate default methods, the code will
Implementing Multiple Interfaces A class can implement multiple interfaces using the following syntax: C#Copy publicclassCDAndDVDComboPlayer:ICDPlayer,IDVDPlayer If a class implements more than one interface where there is ambiguity in the names of members, it is resolved using the full qualifier for...

To declare a class that implements an interface, you include animplementsclause in the class declaration. Your class can implement more than one interface, so theimplementskeyword is followed by a comma-separated list of the interfaces implemented by the class. By convention, theimplementsclause fol...
The KeyStore class supplies well-defined interfaces to access and modify the information in a keystore. It is possible for there to be multiple different concrete implementations, where each implementation is that for a particular type of keystore....
接口另一主要功能,马克-to-win: 可以使用接口来引入多个类的共享常量。所有的这些变量名都将作为常量看待。所有定义在接口中的常量都默认为public、static和final。原因见后面。 下面的例子当中,如果Server回答的结果是0或1,程序可读性太差,效果绝对没有YES或NO好。所以就把YES和NO放到了Client和Server的共同的接口...
