The difference between Java abstract interface and interface

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 Abstract Interface daemonusersignal{  publicabstractvoid  signal ();}

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

Post-programming results comparison:

d:\git\concurrent_crypto\target\classes\com\abstractinterface>"Daemonusersignal.java  "interface com.abstractinterface.DaemonUserSignal {public  abstract void Signal ();} D:\git\concurrent_crypto\target\classes\com\abstractinterface>"  Daemonusersignal2.java"interface Com.abstractinterface.DaemonUserSignal2 {  public abstract void signal ();}
