Question

what is interface ?? ​

Answer 1

Answer:

$\huge \underbrace \mathfrak \green{interface}$

An interface is a reference type in Java. It is similar to class. It is a collection of abstract methods. A class implements an interface, thereby inheriting the abstract methods of the interface. Along with abstract methods, an interface may also contain constants, default methods, static methods, and nested types.

Answer 2

$\huge \cal \underline \color{lime}★A᭄ɴsᴡΣʀ࿐$

• Think of an interface as a "face-to-face," a place where things, or people, or people and things (like you and your computer) meet. Any common boundary or area of convergence can be an interface.

• Used as a verb, interface means to merge or mingle, bonding and synthesizing by communicating and working together.
