   Jun 10, 2024 · An interface in Java is a contract or a blueprint that defines a set of abstract methods, constants, and static methods. It specifies what a class must do but does not provide any implementation details. Classes that implement an interface must provide concrete implementations for all the abstract methods defined in the interface.

   What is the difference between an interface and an abstract class?

   • Access Modifiers: Abstract classes can have public, protected, and private access modifiers for their members, while all methods and variables in an interface are implicitly public. Constructors: Abstract classes can have constructors, allowing for initialization and instantiation of subclasses, while interfaces cannot have constructors.

   How do interfaces and abstract classes promote abstraction in Java?

   • Here’s where interfaces and abstract classes step in as powerful tools to promote abstraction in Java: Interfaces: These act as contracts, specifying the behavior (methods) a class must implement. They define the “what” – what functionalities a class must offer – but leave the “how” (implementation details) up to the class itself.

   Why is interface a pure class?

   • Method: a. Every method present inside an interface is always public and abstract, whether we are declaring or not. That’s why interface is also known as a pure (100%) abstract class. b. An abstract class can have both abstract and non-abstract (concrete) methods.
