Node JS vs Java: Difference and Comparison

Developers use Node.js and Java for different applications and write them using different languages. The Node.js platform was established by Ryan Dahl, an American developer, in 2009. On the other hand, Java was created by James Gosling. 

Key Takeaways

  1. Node.js is ideal for developing server-side web applications that require high scalability, whereas Java is better suited for building complex enterprise-level applications that require multi-threading and high performance.
  2. Node.js is a single-threaded language that utilizes non-blocking I/O to handle multiple client requests simultaneously. In contrast, Java is a multi-threaded language that relies on thread management to handle multiple tasks concurrently.
  3. Node.js uses JavaScript as its programming language, making it an excellent choice for full-stack developers who want to work with a single language throughout development. In contrast, Java is a more traditional language used in enterprise-level applications.

Node.js vs Java 

The difference between Node.js and Java is that Node.js is a scalable server-side application, and its framework is mainly written in C++. C. and JavaScript, whereas Java is used to create highly complex applications and its entire framework is mainly derived from just one programming language, C++. 

Node.js vs Java

Node.js is a platform for executing JavaScript code. It is built on Chrome V8, a JavaScript engine that converts JavaScript calls to machine code.

This is the distinction between Node.js and JavaScript: the former is an operating environment for the JavaScript language, while the latter is a programming language.  

James Gosling of Sun Microsystems created Java. The JDK (Java Development Kit) is a package that includes all the components needed to run a Java application.

The most recent version is Java 10, released in March 2018. Its frameworks include Hibernate, Struts, JSF, etc.

Parameters of Comparison Node.js Java 
Application Type Scalable server-side applications It has created highly complex applications. 
Application It is used for applications that modify real-time data. It is used for applications that create objects and manage data. 
Frameworks Express.js, Partial.js, and Sails.js JSF, Hibernate, Struts, etc. 
Installation You need to install an npm and an archive file on a system. You need to install JDK (Java Development Kit). 
Creation The framework is written using C++, C, and JavaScript. It is derived from C++. 
Scope Developers utilize it on the client and server sides. It is used to dominate server-side interaction. 
Project It is suitable for smaller-sized projects. It is suitable for more complex projects that are web-based. 
Usage It is useful for scalable and faster application requirements. It is useful for web applications, messaging, highly concurrent applications, etc. 

What is Node.js?

Rayn Dahl created Node.js to use JavaScript outside the browser, and Joyent eventually took it over. Node.js is used for both front-end and back-end development and may also be used to create mobile apps.

The Node.js platform was established by Ryan Dahl, an American developer, in 2009. While the developers extensively used the “one thread for each connection” idea, Dahl’s new platform was centred on events. The system’s main goal was to create scalable network servers. 

Node JS has many server-side features; for example, a developer can do various things like listening, accessing the database directly from the computer, and listening to network traffic.  

Its characteristics allow it to manage the server side, allowing users to request a packet while accessing the database. Express.js and Node.js are the foundations for several JavaScript frameworks.

However, these frameworks may be used depending on the application type. Node.js has the advantage of being able to connect to devices via APIs as well as libraries built in other languages. 

Because Node JS permits using the same JavaScript for front-end and back-end programming, it is very easy to use. Developers may create real-time applications while also having the ability to create mobile applications. 

To solve scalability, Node JS uses an event-based approach, which allows for extensive JavaScript libraries for JavaScript modules, which makes writing easier. Numerous Node JS frameworks are available, including Express JS, Partial JS, and others.

What is Java?

James Gosling created Java at Sun Microsystems, and Oracle later acquired it. It is an object-oriented programming language. The Java Development Kit (JDK) contains the entirety of Java and is sufficient to run any Java program.  

It converts code into byte code, which can be run on any machine with Java installed, regardless of the operating system. Java has a large community and allows networking and graphical user interfaces.

Many games are written in Java and are widely utilized. Several frameworks, such as Spring on the server side, are built on Java for web development. Its syntax is majorly derived from C++.  

Java has a lot of concurrencies, networking, and graphical user interface capability (Graphic User Interface). The Java platform is used to create a wide range of frameworks.

Based on the Java platform, today’s online development scene is dominated by Spring. The Java compiler converts a Java source program into bytecode, which can be executed on any operating system.

The operating system needs to have a compatible Java Runtime Environment. One of its most significant advantages is that the source code written in java is capable of running on any platform.  


Main Differences Between Node.js and Java 

  1. Node.js is used for scalable server-side applications, and Java has created highly complex applications. 
  2. Node.js can create applications that modify real-time data, and Java is used for applications that create objects and manage data. 
  3. Node.js includes frameworks like Express.js, Partial.js, and Sails.js, whereas Java includes frameworks like JSF, Hibernate, Struts, etc. 
  4. Node.js requires an npm and an archive file to be installed on the system, and for Java, you need to install a Java Development Kit. 
  5. Node.js is written using C++, C, and JavaScript, and Java is written using mainly C++ only. 
  6. Developers can use Node.js on the client and server side, and Java can be used to dominate server-side interaction.
