Java 8 new features 1. Lambda Expressions A lambda expression is an anonymous function. A function that doesn’t have a name and doesn’t belong to any class. so compiler does not create .class file. Used to provide the implementation of an interface which has functional interface //Syntax of lambda expression ( parameter_list ) -> { function_body } Example: Creating Thread with Lambda package com.vasanth.java8; public class ThreadWithLambda { public static void main (String args[]){ //Traditional approach Runnable r1= new Runnable() { @Override public void run() { System. out .println( "Thread 1 started" ); } }; Thread t1= new Thread(r1); t1.start(); //With Lambda Runnable r2=()->{ System. out .println( "Thread 2 started" ); }; Thread t2= new Thread(r2); t2.start();
