What is the Difference Between Java and J2EE?
🆚 Go to Comparative Table 🆚Java and J2EE (now known as Java EE) are related but serve different purposes in the world of software development. Here are the key differences between them:
- Purpose: Java is a general-purpose programming language used for various applications, including desktop applications and server-side applications. J2EE, on the other hand, is a set of specifications targeting enterprise technologies like JMS, Web Services, Servlets, JSP, and EJBs, which are implemented using Java.
- Foundation: Java is the foundation for J2EE. J2EE is an extension of Java SE (Java Standard Edition) and is used for developing large-scale enterprise applications.
- APIs: Java SE provides the core APIs for developing applications, while J2EE adds additional APIs and tools necessary for large-scale enterprise applications.
- Application Type: Java is typically used for developing desktop applications, while J2EE is used for developing server-side applications, such as web applications and web services.
- Popularity: Java is a widely used programming language, with a presence in web applications, websites, gaming consoles, laptops, and Android devices. J2EE, while not as ubiquitous as Java, is still widely used for developing enterprise applications.
In summary, Java is a programming language used for various applications, while J2EE (now called Java EE) is a set of specifications and APIs built on top of Java SE to provide the tools necessary for developing large-scale enterprise applications.
Comparative Table: Java vs J2EE
Here is a table highlighting the differences between Java and J2EE (Java Enterprise Edition):
Feature | Java | J2EE |
---|---|---|
Purpose | General-purpose programming language, used for various applications | Platform for creating server-based applications, specifically designed for web-based server-side development |
Focus | Developing mobile and desktop applications | Developing large-scale enterprise applications with a focus on server-side technologies and APIs |
APIs & Classes | Contains all Java APIs and classes | Offers a standardized set of APIs and features geared towards server applications |
Java Platform | Java SE (Standard Edition) | Java EE (Enterprise Edition), now known as Jakarta EE (formerly J2EE) |
Ease of Use | Spring framework targets Java SE development, providing simpler implementation for developers | Spring framework targets Java EE development, simplifying enterprise application development with Java Beans |
In summary, Java is a general-purpose programming language, while J2EE (Java 2 Platform, Enterprise Edition) is a platform specifically designed for developing server-based, web-focused applications. Java SE (Standard Edition) provides basic programming functionality, while Java EE (Enterprise Edition) offers additional features, APIs, and standards tailored for large-scale enterprise application development.
