Do you know the difference between java and javascript? Non-tech people like us might get confused between both these terms. There is only one common thing in both these terms, that is the word “java”! In today’s post, you will get to know the basic difference between java and javascript in detail. In this Java vs Javascript tutorial, you will learn the important features of java as well as javascript. And make sure you do not miss to check out their applications too. If you are interested to learn the difference between java and javascript, then you can keep on reading.

What Is The Difference Between Java And Javascript?

Many new programmers think that java and javascript are similar languages. But the fact is that javascript has nothing to do with the java programming language. Here, I have listed down some of the key differences between java and javascript language.

JavaJavascript
Firstly, Java is a programming language.Whereas Javascript is a scripting language designed to create interactive web pages.
It is an object-oriented programming language.It is an object-based scripting language.
It should be compiled before execution, so it is a Standalone language.It needs to be integrated into an HTML program for execution, so it, not a Standalone language.
Here, the user has to decide the data type of the variable before declaring and using it.Here, the user does not have to worry about the data type of the variable before and after the deceleration.
You do not require a web browser to run the java program.You do need a web browser to run the javascript programs.
Java is one of the hard and complex languages to learn.While javascript is one of the easiest languages to learn.
By utilizing the Multi-threading feature, users can easily perform complicated tasks.On the other hand, users will not be able to perform any complicated tasks in javascript.
Users may need a large amount of memory for this programming language.Users do not need large memory for this programming language.
They were developed by Sun Microsystems.They were developed by Netscape.
The programs in this programming language are saved with the .java extension.The programs in this programming language are saved with the .js extension.
They are stored on the host machine as Byte code.Whereas this programming language is stored on the host machine as the source text.
For example “int a”, the variable “a” can store the value of integer type only.For example “var a”, the “a” variable can store the value of any data type.

As now you have learned the difference between java and javascript code, let us see their features.

Features Of Java

We all know java is the most used programming language across the globe. It was first released by Sun Microsystem in 1995 and was later acquired by Oracle Corporation. Here, I have mentioned some important features of Java, just have a look at them.

  • This programming language runs on almost any computing platform.
  • Java is a multi-threading language that has automatic memory management.
  • Generally, it facilitates distributed computing as it is network-centric.
  • This programing language is designed for building object-oriented applications.

Now, let us explore the features of javascript.

Features Of Javascript

As Javascript follows all the rules of client-side programming, it usually runs on the user’s web browser. Thus, they don’t need any additional resources from the webserver. Now, let us learn its important features.

  • This programming language is widely used for client-side and server-side programming.
  • It is a cross-platform programming language.
  • They have a strong testing workflow.
  • It one of the easiest languages to learn and start with coding.

Applications Of Java And Javascript

Here, are some important applications of java and javascript.

JavaJavascript
1. Android Apps1. SPAs: Single-Page Applications
2. Enterprise Software2. Used in front-end technologies like jQuery, AngularJS, Enber.js, ReactJS, etc.
3. Scientific Computing Applications3. Used in server-side technologies like Node.js, Express.js, MongoDB, and more.
4. Big Data Analytics4. Used in mobile app development using PhoneGap, React Native, etc.
5. Java Programming of Hardware devices
6. Used in server-side programming like Apache, JBoss, GlassFish, and more
