Because JavaScript's name is similar to Java, people often think that JavaScript is a part of the Java platform, but Java is completely different from JavaScript. The following are the differences between Java and JavaScript:

JavaScript vs Java

Difference between Java and JavaScript | java vs JavaScript

  1. JavaScript is an OOP scripting language while Java is an OOP programming language.
  2. JavaScript runs only in the browser whereas Java code runs in both the JVM and the browser.
  3. JavaScript code is simple and not complicated whereas Java code is complicated and difficult.
  4. JavaScript is used with HTML to create dynamic web pages whereas Java is used to create stand-alone and live applications using applets.
  5. It can be run in the browser without being compiled, whereas we have to compile Java code.
  6. JavaScript supports more platforms than Java.
  7. Java objects are class-based whereas JavaScript objects are prototype-based.
  8. JavaScript is a dynamically typed language whereas Java is a statically typed language.
  9. JavaScript is not a stand-alone language, it is used with HTML, whereas Java is a stand-alone language and does not require any other language.

Advantages of JavaScript

  • Essential for Web Development: JavaScript is used for websites and web applications.
  • Interactive User Interface: It makes the user interface interactive and dynamic.
  • Many Frameworks and Libraries available: Many popular libraries and frameworks like React, Angular, and Vue.js are available.
  • Rapid Development: Its simplicity and flexibility allow for rapid development.

Advantages of Java

  • Portability: Based on the "Write Once, Run Anywhere" principle, Java can run on different platforms without modification.
  • Widespread Use: Used extensively in large-scale enterprise applications, mobile apps (Android), and back-end systems.
  • Robust Security: Java has strong security features, making it ideal for enterprise applications.
  • Multithreading: Java has multithreading capability, allowing multiple tasks to be performed simultaneously in the same program.
  • Community and Support: Java has a large community and extensive support, making it easy to find solutions to problems.

It is clear that both JavaScript and Java have their own characteristics and use cases. While JavaScript leads in web development and interactive applications, Java has established its place in enterprise applications and back-end systems.
