We often encounter the difference between abstract class and interface, but today encountered an abstract interface, feel interface do not have to abstract again ah. Conclusion: This is true, after compiling the. class file, the abstract interface becomes the interface.

 Package Com.abstractinterface;  Public Interface daemonusersignal2{  publicabstractvoid  signal ();}
