Bookmark or Share- Interface in java - JavatpointInterfaces play a crucial role in Java programming, enabling the creation of modular, extensible, and maintainable codebases. By defining contracts for classes to adhere to, interfaces promote abstraction, polymorphism, and separation of concerns.
- Java Interface - GeeksforGeeksTo declare an interface, use the interface keyword. It is used to provide total abstraction. That means all the methods in an interface are declared with an empty body and are public and all fields are public, static, and final by default. A class that implements an interface must implement all the methods declared in the interface.
- Java Interface - W3SchoolsAnother way to achieve abstraction in Java, is with interfaces. An interface is a completely " abstract class " that is used to group related methods with empty bodies: To access the interface methods, the interface must be "implemented" (kinda like inherited) by another class with the implements keyword (instead of extends).
- What Is an Interface? (The Java™ Tutorials - OracleImplementing an interface allows a class to become more formal about the behavior it promises to provide. Interfaces form a contract between the class and the outside world, and this contract is enforced at build time by the compiler.
