Node.js vs Java

Node.js: Node.js a library that is used to create runtime application. It was initially written by Rayn Dahl for using the JavaScript outside browser and later on it was managed by Joyent. Node.js is used for both front-end as well as back-end and developers can build mobile applications as well. With its capabilities, It can handle the server-side, a user can request a packet and at the same time, it can access the database. JavaScript has plenty of frameworks that are based on Express.js and Node.js. But when depending on the type of application these frameworks are decided to be used. This is an advantage of node.js that it can connect to devices using APIs and can connect to libraries written in other languages too.

Example: Printing ‘Welcome to GeeksforGeeks’ in Node.js.

Java: Java was developed at Sun Microsystems by James Gosling and later on, Oracle took it over. Java is an object-oriented language whose most of its syntax is derived from C++ and their concepts remain the same with some modifications. Whole Java comes in a bundle with JDK called Java Development Kit and it is enough for a java program to be get run. The code written in Java is converted into byte code which can be run on any machine irrespective of the operating system that has Java and this one of the biggest advantages of this language. Java has a huge community and it supports networking and GUI. Many games are built on Java and are used extensively. Several frameworks are built on Java for the web development, example Spring.

Example: Printing ‘Welcome to GeeksforGeeks’ in Java.

Difference between Node.js and Java:

Basis of Node.js Java
Application Type Server side applications which are highly scalable. Highly complex application have been created.
Creation Resembles the C, C++ and JavaScript conventions as framework is written in these. Object oriented structure applications derived from C++.
Installation This requires to install npm to run Node.js. It requires Java Development Kit to run Java.
Developers Usage It is used for small projects and server-side interactions. It is used for CRUD operations based projects which are complex to handle.
Community Support There are a huge community to support. Java community has been the most versatile so far and has huge supporter’s too.
Frameworks It has many frameworks such as Sails.js, Express.js, and Partial.js It has frameworks named JSF, Struts, Hibernate, etc.
Application Used in applications where real time data is modified example Google Docs. Used in applications where object creation is needed and data is managed.
