Java vs JavaScript: What’s the Difference?

 

Over 289 people have rated [5/5]

 

I often get asked that is JavaScript similar to Java. Or vice versa. The things are that Java was solely intended for implementing the cross-platform execution of applications. Meaning that applications written in Java can be executed on any machine or on any platform, Windows, Linux, Unix, Mac. Java does not have complex requirements to run.

 

It just requires the Java Development Kit for executing Java programs. The source code is first converted to byte code by the Java Compiler and then from byte code to the machine-readable code in the second stage of execution.

 

JavaScript was created with the sole purpose of adding interactivity and validation for online forms. JavaScript can be executed solely on a browser and is used for creating Front end applications. There are many frameworks that exist for JavaScript that provides a different kind of functionality to the programs.

Java

JavaScript

Java is an Object-Oriented Programming Language developed by James Gosling of Sun Microsystems that was later acquired by Oracle.

JavaScript is a Client-Side Scripting language created by Netscape and was originally known as LiveScript.

This is the standalone language that is executed by the Java Virtual Machine (JVM) that needs to be compiled into Byte-Code and has the file extension “.java”

JavaScript’s code must be placed inside an HTML document and executed by a web browser such as Google Chrome or Mozilla Firefox and has the “.js” file extension

Java works on class-based objects and you will not be able to program in Java without creating a class.

JavaScript works by using the Prototype-based concept

To execute Java programs, you will require the entire Java Development Kit (JDK)

To write JavaScript programs you only require a text editor such as Notepad, Notepad++ or WordPad.

Java supports the static type of checking for programs

JavaScript supports the dynamic type of checking for programs

The full source code is hidden as the code is compiled into an unreadable byte-coding type.

The source code can be read by any person as it is written in plain text.

Java is developed by keeping the “security of codes” as the primary motive that can be achieved through JVM.

JavaScript is less secure and you have to constantly make efforts to secure its coding from cross-site scripting, etc

Java supports class concurrency that allows to  work with many threads and help maintain parallel concurrency in coding

Concurrency is based  on the queue system “event loop” that is able to support and provide features as async/await in coding

Java is a compiled language

JavaScript is an interpreted language

Java is mainly used for backend programming

JavaScript is mainly used for FrontEnd programming

Java can either be executed by a JVM or by a browser

JavaScript is solely executed in the browser.

Java offers strong security features compared to JavaScript

JavaScript needs more effort to provide enhanced security.

The syntax is similar to C++

The syntax is similar to C

Java can be used for creating various kinds of apps.

JavaScript is used mainly for Web Apps

Conclusion:

So now you know that Java is used for general programming purposes and JavaScript is used for Front end programming purposes. We hope you have gained some insight into what Java and JavaScript is all about.

HTML5 vs JAVA

470 People Voted 5/5

  • Recently there has been a major boom in developing technologies that serve to solve a particular computing problem.
  • After the dot COM bubble, there has been a major outburst in emerging IT technologies that support Web Server as well as Desktop based application programming. Every Programming language solves a particular computing problem
  • Here in this article, we will have a look at the distinct features of two of the most popular Desktop application programming as well as Web Programming languages available to us today.

 

What is Java?

It is a General Purpose Language. It is also a class-based programming language that supports Object-Oriented Programming. And is also a platform independent language which means it can run on any platform.

Java requires a JVM (Java Virtual Machine) for running applications. Because of JVM, Java gets its platform Independency feature. It has minimal dependencies to run. It is a compile-once-run-anywhere language, and this means that you don’t have to recompile the language again and again.

 

Java runs on an Object-based model and encourages code reusability and extensibility.

 

The main problem addressed by the Java language is platform independence. How to bring the feature of platform independence and implement it in a programming language. The inventors did this by bringing the concept of Java Virtual Machines (JVM).

Let us have a look at the different features of Java. What makes Java the language that it is today?

 

  1. Java is simple and easy to learn. Users with little or no programming background can easily learn the language concepts and start implementing it in their programs.
  2. It is platform independent which means that Java programs can be run and executed on any platform.
  3. It is a secure language. Java has secured memory accessibility structure. 
  4. Java is portable.
  5. It is an architecturally neutral language, this means that Java does not know the details of the architecture of the platform it is running on.
  6. Java programs are multi-threaded. This feature allows developers to design programs that can run uninterrupted and smoothly
  7. The Just in Time compiler enables Java to provide high-performance applications.
  8. It is considered to be a much more dynamic language than any other language such as C or C++.
  9. It is a distributed language. Java is made for the Internet.

What is HTML5?

 

HTML5 is the newest revision to HTML markup language. Web browsers support HTML5. Browsers can only understand HTML. Browsers receive the HTML code in response to a server web page request.

HTML5 brings the following types of content:

  • Videos that can be used to display videos inside web-pages,
  • Figures which can be used to display visual content like images or photographs, diagrams, illustrations, code snippets, etc,
  • Nav elements work similar to ordered or unordered lists that can be used to link to parts of the webpage or can be linked to other web pages,
  • Section tags that can be grouped into particular sections
  • The header tag which can be used to provide introductory elements to web pages such as logos, navigation or a form to be searched for.
  • The footer tag which can be used to provide social media links, copyright information or additional site navigation items

HTML adds structure to a web document. Along with the CSS to style the document and JavaScript to add user and document interactivity to it

To sum up, HTML5 is a Browsers language.  Any Internet browser can understand HTML. There are many technologies that provide server-side processing as a result of input for the user’s data and provides HTML as an output of processing.

 

Comparison

 

Here is a raw comparison between the programming capabilities of these two languages.

JAVA vs HTML 5 

Conclusion:

  • We have seen and understood the major differences between these languages. We have also seen the features of these languages.
  • Although these languages are used for different applications altogether, it is worthwhile knowing where to use which language.
  • Since there may be different environmental applications that may be suited for each language. And a different environment would demand a different language.
  • We hope you liked this article and have enjoyed reading it. If you have found this article informative, do check out our other posts.
