Java vs JavaScript

Java Vs JavaScript

Java and JavaScript, both play an important role in the field of Computer Technology. Most people think JavaScript is a part of Java. But it is not entirely true. Java is a programming language whereas JavaScript is a scripting language. In this section we will discuss the differences between Java and JavaScript.

What is Java?

  • Java is an object-oriented programming language, released by Sun Microsystems in the year 1995.
  • Java programming is most popular programming languages because of object-oriented. It is platform-independent. It does not support explicit pointers that makesJava programs more secure.
  • One must install JDK before executing the Java program. The Java code is first compiled into byte code and then it is interpreted. The byte code can be executed on any other platform which has Java Virtual Machine (JVM) installed on it. This makes the Java programs portable.
  • There are three versions of Java.
  • Java SE (Standard Edition)
  • Java EE (Enterprise Edition)
  • Java ME (Micro Edition)   

Applications of Java

Java Programming can be used to develop:

  • Mobile applications
  • Desktop GUI applications
  • Web applications
  • Big data technologies
  • Cloud based applications
  • Distributed applications
  • Server side technologies like Apache, Glassfish, etc.

Java program Example

The following program demonstrates how to write a basic Java program.

 /* Declaration of Class */
 class Sample
     /* Driver Code */
     public static void main(String ar[])
       /* Print statement */
 System.out.println("Hello World"); 


Hello World

The above Java program, declares a class Sample. The System.out.println() method displays the output on the console.

What is JavaScript?

  • JavaScript is a scripting language that allows us to develop interactive web pages on the client as well as server-side.
  • The JavaScript code is inserted inside HTML using <script> tag. JavaScript is executed on the client side.
  • JavaScript is easy to learn and can be used with other languages for developing web applications.
  • For executing JavaScript programs we don’t need to install any kind of plug-ins.
  • JavaScript is used with differentprogramming paradigms like REST API, Node.js, etc.

JavaScript program Example

The following HTML code demonstrates how to write basic JavaScript program.

 <!DOCTYPE html>
 <html lang="en">
 <meta charset="UTF-8">
 <title>JavaScript Example</title>
 alert(“Hello World”);


Hello World

The above HTML code has JavaScript in it using <script> tag.

Applications of JavaScript

JavaScript can be used to develop:  

  • Websites
  • Web applications
  • Single Page Applications (SPA)
  • Games
  • Mobile applications
  • Server side applications

Similarities between Java and JavaScript

There are a few common features among Java and JavaScript. They are as follows:

  1. Object-Oriented Programming (OOP):

Java and JavaScript both languages work on objects. Therefore, they both follow object-oriented features like polymorphism, inheritance, and encapsulation.

  • Front end development:

Java programming allows front end development with the help of Applets. JavaScript is used for developing web applications.

  • Back end development:

Java and JavaScript both can be used as server-side technologies. Java programs support backend technologies like Apache, Glassfish, etc. JavaScript can be used along with Node.js for back end development.

Which is better Java or JavaScript?

Both the languages, Java and JavaScript are important in their own ways. According to the requirements one should decide which language to use. JavaScript is mostly used with web applications. On the other hand, Java can be used to develop any kind of software as it is a general-purpose programming language.

Java vs JavaScript

Sr. No.JavaJavaScript
1.Java is an object oriented programming language.JavaScript is an interpreted, object-based scripting language.
2.Java is released in the year 1995 by James Gosling at Sun Microsystems.JavaScript is released in the year 1995 by Brendan Eich at Netscape.
3.The Java programs are executed on Java Virtual Machine.The JavaScript programs are executed on a web browser.
4.The Java programs are standalone programs.The JavaScript programs are embedded inside HTML.
5.Java uses threads to maintain concurrency control.JavaScript uses events to maintain concurrency control.
6.Using Java, we can develop desktop, web, or mobile applications.JavaScript can be used to develop web applications.
7.Java programs are compiled and then interpreted using Java runtime environment.JavaScript programs are directly interpreted.
8.The Java programs are stored using the .java extension.The JavaScript programs are stored using the .js extension.
9.Java programming supports a multithreading mechanism.JavaScript doesn’t support a multithreading mechanism.
10.More memory is required for Java program execution.Less memory is required for JavaScript programs.
11.Java programming is a static language.JavaScript is a dynamic language.

In this article, we have discussed what is Java and JavaScript, their applications, what is difference between both these languages.
