An Interface in Java is an abstract type that defines a set of methods a class must implement. An interface acts as a contract that specifies what a class should do, but not how it should do it. It is used to achieve abstraction and multiple inheritance in Java . We define interfaces for capabilities (e.g. Comparable, Serializable, Drawable). A class that implements an interface must implement all the methods of the interface . All members of an interface are public, static, and final by ... Discover what an interface in Java is and how it enhances code abstraction. Learn its importance, benefits, and implementation with practical examples. Interfaces in Java are a fundamental part of object-oriented programming that help achieve abstraction and multiple inheritance. This article will explain what an interface is, how it works, and why it’s important.
