More Information
Java interfaces allow classes to implement methods without providing the method implementations, encouraging multiple inheritance and providing a way to enforce certain methods in multiple class hierarchies.
Tips
Avoid confusing 'interface' with 'class' or 'abstract class'. Also, remember that interfaces can extend multiple other interfaces and cannot have constructors.
