A lambda expression arebrief representation of an anonymous function that can be passed around: it doesn’t have a name, but it has a list of parameters, a body, a return type, and also a list of exceptions that can be thrown.

Some other Lambda expression syntax are: No Parameter Syntax () -> { //statements for lambda } One Parameter Syntax (x1) -> { // statements for lambda } Two Parameter Syntax (x1 , x2) -> { //statements for lambda } Why there is a need of Lambda expressions?
Let’s understand functional interface to understand the usage of Lambdas expressions. Functional Interfaces Functional Interface is an interface which have only one method to abstract. An annotation is added so that we can mark an interface as functional is an @Functional Interface . It is not compulsory to use , but it’s good practice to use it with functional interfaces so that extra methods will not be accidently added. If the interface is annotated with @FunctionalInterface annotation and if you add more methods to it , it throws compiler error. @FunctionalInterface //It is optional interface Color{ public void paintColor(); } public class LambdaExample { public static void main(String[] args) { int size=15; //lambda expression Color c=()->{ System.out.println("Coloring"+size); }; c.paintColor(); } } This article is contributed by Skillyfy.
