Hi, interface and type, looks similar but interfaces can use for declaration merging and extends and implements which type cannot do. When would one want to use an interface. Gui is graphical user interface and ui is just user interface. gui is a subset of ui.

An interface in java is a special type of abstract class, the interface provided the 100% abstraction but since the java introduce new features in java 8 the meaning of whole interface is.
42 the interface keyword indicates that you are declaring a traditional interface class in java. But implemented by a single class then how the compiler will identify the which method is for which interface?
