class Example {

// this code is all about the lambda expression in java 8...

// normal function without using the lambda expression -->

public void method1() {

System.out.println("Hello World!...");

}

// when we use the lambda expression for above code section -->

// () -> {System.out.println("Help!!")}

* Important things which we can remember when we convert any normal function in

* the lambda expression.

* When lambda expression executing any java.class file not created so it comes

* in java with enable functionality and

* compact and concise way to write the functional interfaces.

* Three major rules are to be remember --

* 1. remove the access modifeir

* 2. remove the return type

* 3. remove the method name

* Lambda expression is used for the passing the comparator for any function.

* eg. when we sorted via comparator then we use the following -->

* (a,b) -> a-b; --- for asending order

* (a,b) -> b-a; --- for desecending order
