Java interfaces
Understand the Problem
The question is asking about Java interfaces, which are a fundamental aspect of the Java programming language that allows the definition of methods without implementations, enabling a contract for classes that implement them.
Answer
An interface is a blueprint including static constants and abstract methods, used for achieving abstraction and multiple inheritance.
In Java, an interface is a blueprint for a class that includes static constants and abstract methods. It is used to achieve abstraction and multiple inheritance.
Answer for screen readers
In Java, an interface is a blueprint for a class that includes static constants and abstract methods. It is used to achieve abstraction and multiple inheritance.
More Information
Using interfaces allows different classes to have common method signatures, promoting modularity and flexible code design.
Tips
A common mistake is not providing implementations for all abstract methods in an interface. Always ensure the implementing class defines all methods.
