Difference between Java and JavaScript

What is Java and JavaScript?

Java and JavaScript have long been mistaken by new programmers and non-technical people, yet the only thing they have in common is the word “Java.” Each is a useful programming language in its own right, with advantages over each other. Programmers utilize both Java and JavaScript for a range of utility, thus one isn’t inherently better than the other.

From that point onward, the evolution of the two programming languages took such divergent trajectories that it’s a running joke that Java is to JavaScript what ham is to a hamster. But, because you’re reading this, you’re presumably looking for a more practical explanation of these two widely using languages. so let me compare them.

There would be a straightforward comparison if we traveled back in time around 5 years, such as Java is a general-purpose coding language, and JavaScript is used on web applications to make them interactive and animated. The comparison is much more nuanced now that JS has “matured.”

Know about Java 

Java is one of the  object-oriented programming language with a virtual machine platform that allows you to compile and run programs on almost any platform. “Write Once, Run Anywhere,” Java promised.

  • Netscape, Inc. created the JavaScript programming language, which is not part of the Java platform.
  • Java applications run in a virtual machine or in a web browser, whereas JavaScript runs in a browser.
  • Java code is in text and on a web page, whereas JavaScript code is written in text and placed on a web page.
  • JavaScript is an object-oriented programming language, while Java is an object-oriented programming language.

Know about JavaScript

Internet Explorer and Netscape Navigator are the two most popular web browsers used by the general public in the early days of the Internet, around 1990. Brendan Eich, a developer at Netscape, Inc.,. It was able to construct a programming language that could teach a computer to engage with a user after receiving user input in just ten days. He coined the term “LiveScript” for the language and put it directly into the navigator.

This meant that the browser was directly interpreting the user’s commands; there was no need to build the code and no need for plug-ins. on the same time, another programming language, Java, was gaining popularity, instead of the fact that Java require a separate plug-in to perform the function. Netscape spotted an opportunity and coined the term “JavaScript” to describe its programming language. In the early days of the Internet, JavaScript was unavoidable.

Difference between Java and JavaScript

Both Java and JavaScript are in, built, and execute differently, and they have significant distinctions in what they can do.

Java is using in a variety of applications, such as Android apps, credit card programming, and the development of desktop and web enterprise applications. JavaScript, on the other hand, is another popularly using to make web pages more interactive. Anyhow most programmers will say you that JavaScript is popular and has more capabilities than Flash. It can be utilize as an alternative. It is utilize in a variety of applications, such as Android apps, credit card programming, and the development of desktop and web enterprise applications. 

Java Vs JavaScript

Java is normally utilize for all server-side development. Whereas JavaScript is reserving for building client-side scripts for features such as validation and interactivity. There are a few other differences:

  • JavaScript code is in all-text, and Java code must be compiled.
  • Different plug-ins are require for each language.
  • JavaScript code can only be run in a browser. But Java generates apps that can be run on a virtual machine or a browser.
  • Java is an object-oriented programming (OOP) language, while JavaScript is a scripting language for OOP.
  • Any virtual machine (JVM) or browser may run Java applications.
  • JavaScript code used to just run in the browser, but thanks to Node.js, it can now run on the server as well.
  • Java objects are class-base, and we can’t write a program in Java without first establishing a class.
  • Prototypes are the foundation of JavaScript Objects.
  • The “.Java” file extension says a Java program that converts source code into bytecodes, which are run by the JVM.


I hope that this post serves as a definitive guide to the differences between JavaScript and Java. Now, if you’re bored of reading/researching about web app development and you’re short on time, I propose reading this post, which I believe will save you time. Today, software development organizations in India and throughout the world use both of these programming languages to build safe, scalable, and feature-rich programs that meet the needs of businesses.

A new programmer will discover that both Java and JavaScript are useful languages to have in their toolbox. Many programmers and developers believe that studying these two languages, early on, is a sensible approach for a novice programmer. Without any question, knowing Java and JavaScript will make a programmer more employable and lead to additional new opportunities.
