What can be the modifiers of java interface

The modifiers of java interface can be abstract and final. The interface can be understood as a special class. The difference is that the members of the interface have no execution body and are composed of global constants and public abstract methods; the methods of the interface are public abstract by default; and variables cannot be defined in the interface. Constants can be defined (with final modification, they will become constants), so the properties of the interface are public static final constants by default and must be assigned an initial value.
