Java 8 Functional Interfaces
In this post, we will learn the Java 8 the functional interface with examples.Key points about the functional interface:An Interface that contains exactly one abstract method is known as a functional interface.It can have any number of default, static methods but can contain only one abstract method. It can also declare methods of the object class.Functional Interface is also known as Single Abstract Method Interfaces or SAM Interfaces. It is a new feature in Java 8, which helps to achieve a functional programming approach.A functional interface can extend another interface only when it does not have any abstract method.The Java API has many one-method interfaces such as Runnable, Callable, Comparator, ActionListener, and others. They can be implemented and instantiated using anonymous class syntax.
