Differences Between Java vs Node JS
Java is an Object-Oriented, general-purpose programming language and class-based. Developers can use the principal – “write once, run anywhere” with Java. It was originally developed by James Gosling at Sun Microsystem.
Much of Java’s syntax is derived from C++, which is also class-based and Object-Oriented. Java is being shipped in the form of JDK (Java Development Kit), which includes various components which are required to run a java program, however, not all the components of JDK are mandatory to run Java. The latest version is Java 10, released on March 2018.
Node JS allows developers to execute their code on the server side. It provides a faster way to write scripts which are scalable and light. Developers can write the real-time applications, and at the same time, it provides scope for mobile application development.
Java source program is converted to bytecode by the Java compiler, and then this compiled bytecode can be executed on any operating system having compatible JRE (Java Runtime Environment) installed on it. Thus, source code once written in Java can be run on any platform, which is one of the biggest benefits. It is just that appropriate JRE must be installed on a required operating system which can be downloaded from Java’s official website.
Java is portable, means program written for any platform must run similarly on a combination of hardware and operating system. A compiler would convert Java source code to bytecode, and JVM (Java Virtual Machine) which is created inside JRE (Java Runtime Environment) would convert bytecode to machine code. Java has extensive support for concurrency, networking, and GUI (Graphic User Interface).
There is a vast number of frameworks which are built using Java. In the current scenario, Spring is vastly used in the web development landscape whose foundation is laid upon Java.

Key Differences Between Java vs Node JS
Some key Differences Between Java vs Node JS are explained below
- Java is a great option for building complex web-based, highly concurrent application whereas Node JS is ideal for developing small size projects.
- Java requires Java Development Kit which includes Java compiler and runtime environment to run Java on any machine whereas Node JS must be installed through installable archive file.
- Java is strictly a server-side language which has nothing to do with the browser, whereas Node JS can be used on client and server side efficiently.
- Java is heavily used for building complex web-based application with an already provided framework built using Java whereas Node JS is best suited for real-time collaborative drawing or editing applications like Google Docs.
- Java uses the concept of multithreading with ease whereas Node JS does not use the concept of multi-threading like Java does.
- For large scale projects that involved concurrency, Java is highly recommended whereas Node JS does not handle the thread as well as Java does, which is the weakest point of this framework.
- CPU intensive task required huge computational power can be handled with Java whereas I/O bound operations like real-time chat, media streaming etc can be handled well with Node JS.
Java vs Node JS Comparison Table
Following is the Comparison Table Between Java and Node JS
| BASIS FOR
|Application||Complex web-based, highly concurrent application||Fast and scalable server-side application|
|Project||Suited for complex web-based concurrency project||Best suited for small size projects|
|Usage||Messaging, web application, highly concurrent application||Highly useful when scalable and faster application is required|
|Installation||Require JDK (Java Development Kit) to run Java||Need to install archive file on a system|
|Scope||Dominate server-side interaction||Developers can utilize it on client and server side|
|Frameworks||Spring, Struts, JSF, Tapestry etc.||Has many different frameworks like Express.js, Sails.js, and Partial.js|
|Application||Simplify application development with Object-Oriented approach||More suited for an application like real-time collaborative drawing/edit like Google Docs|
Conclusion Java vs Node JS
Finally, it depends on what applications one wants to build. Anything done with Node JS can be achieved efficiently with Java libraries and frameworks. Super-fast applications can be built with concurrency in Java, whereas event-driven I/O bound applications can be written efficiently with Node JS framework. At the end of the day, it depends on requirement and developer abilities to understand the technology.
