Difference between JavaScript and Java

JavaScript programming language, is not component of the Java platform.
JavaScript, doesn’t create stand-alone applications and applets. JavaScript is placed inside HTML documents, to provide interactivity levels to web pages that cant be achieved with the simple HTML.

A number of differences between Java and JavaScript are listed below
•Java is a programming language while Java Script is a scripting language.
•Java creates applications that run in a browser or virtual machine but JavaScript code runs on browsers.
•JavaScript code is all in text and doesn’t need to be compiled while Java code needs to be compiled.
•Java and JavaScript require different plug-ins.

Java is a programming language designed to run applets in a Java Virtual Machine on any computer/device that supports a Java Virtual Machine.  Java applets generally do not interact with the Web page itself, but usually runs as a "standalone" program embedded in a Web page.  ParaChat software offers a Java applet option so you can embed a Java chat room in your web page.

JavaScript (originally known as "LiveScript") is a scripting language that runs inside of an Internet browser to manipulate and enhance the contents of Web pages. JavaScript is designed to expand the capabilities of a web page so that it behaves more like a program than just a static page of text and images.

JavaScript is an object-oriented scripting language that allows you to create dynamic HTML pages, allowing you to process input data and maintain data, usually within the browser.

 

Java is a programming language, core set of libraries, and virtual machine platform that allows you to create compiled programs that run on nearly every platform, without distribution of source code in its raw form or recompilation. More on....Java and Javascript

Its easy. Javascript does not create applets or stand alone applications.  In the most common form. javascript resides inside HTML documents.

Difference: 

 

1. Java is an OOP programming language while JavaScript is an OOP scripting language.
2. In Java, there are classes, and instances, as separate concepts. But In Javascript, does not use classes. In JavaScript, you don't define classes and create objects from these classes.
3. Java and Javascript are similar like Car and Carpet are similar.

The difference between Java programming and javaScript is not understood very well normally. Many confuse it to be the same. If one wants to start a career as a developer, one needs to understand the proper difference.

1.Environment to execute: 2.OOP:

Java happens to be Object Oriented Programming language, and however JavaScript likewise bolsters class and object, it’s more similar to an OO scripting language.

3.Constructors:

Java has idea of constructors, which has some extraordinary properties e.g. constructor chaining and guaranteeing that super class constructor keeps running before sub class, then again JavaScript constructors are simply one more function.

4.NullPointerException:

JavaScript is considerably more sympathetic than Java, you don’t have NullPointerException in JavaScript, your variable can acknowledge various types of data on account of JavaScript is powerfully written language..more

Java code must be compiled, and JavaScript code is all-text. ... JavaScript code is run on a browser only, while Java creates applications that run in a virtual machine or browser.

 

Java is an OOP (object-oriented programming) language, and JavaScript is specifically an OOP scripting language.

The main difference between are 
JavaScript can be used to do neat things like creating animation in HTML and JavaScript code is run on a browser only, while Java creates applications that run in a virtual machine or browser. Java is an OOP (object-oriented programming) language, and JavaScript is specifically an OOP scripting language.
