What is the meaning of interface interface in Java?
Why do we use interface ? It is used to achieve total abstraction. Since java does not support multiple inheritance in case of class, but by using interface it can achieve multiple inheritance . It is also used to achieve loose coupling. Interfaces are used to implement abstraction.

The definition of interface is a surface that forms a common boundary between two things or a point of interaction between two components or systems. An example of interface is someone using the controls on a washing machine to tell the machine how to function.
What is interface class?
An interface class is a class that specifies the polymorphic interface i.e. pure virtual function declarations into a base class. The programmer using a class hierarchy can then do so via a base class that communicates only the interface of classes in the hierarchy.
What is Java API class?

What is a Java app?
