Functional interface Tutorial - Java 8 features

Java 8 introduced the functional interface as one of its key features. An interface containing only one abstract method is referred to as a functional interface. This type of interface is specifically designed to support functional programming paradigms in Java. The single abstract method within a functional interface is often called the functional method, and it serves as the signature for the lambda expressions or method references associated with that interface. The @FunctionalInterface annotation is used to explicitly declare an interface as a functional interface, though it's not mandatory for an interface to be functional. The functional interface is also called Single Abstract Method (SAM) Interfaces. Thanks for watching my videos..
