Understanding Difference Between J2EE, J2SE, and J2ME In Java Development

Java is a leading technology for the development of android applications. But when it comes to its various versions, not a lot of people know about them. So, in today's blog, we brought you some interesting information on its various versions and how they differ from each other. Also, this would help you in knowing how choosing a particular version can impact the software development services.

Introduction Java

Meanwhile, we are sure you know Java and its qualities well; let's start our today's session by knowing some amazing facts about Java and what makes it so much popular.

Java is a leading technology used for building various types of products, predominately mobile applications. The technology is general-purpose, which makes it as competitive as Python, and also, it means you can build various types of software using Java and not just focus on its mobile app development qualities. It is a high-level programming language too; it is widely used for building feature-rich applications by a Java development company.

The platform is very versatile and is used for various types of products, such as mobile applications. Embedded systems, web pages, servers, and more. Due to its cross-platform app development compatibility, it is an ideal technology to work with. It makes development cost-effective and worthwhile. Currently, there are more than 9 million Java developers in the world.

Prominent features of Java technology

  • Java is a simple and object-oriented technology.
  • Since JavaScript is one of the most commonly used development languages, you can easily find developers with expertise in the platform.
  • Java platform is robust and secure.
  • The versatility of the platform comes from its architectural neutrality and portability.
  • Allows you high-performance app development.
  • If you want to go for open source development services, there are some trusted Java components you can go with.

Some fun facts about Java technology

  • Java was formally known as OAK, and there is a very interesting story attached to it. The developer that built it had an Oak tree growing outside their house)
  • The logo of Java with the coffee mug too was given to it because of the love for coffee of the developer.
  • It was originally developed by Sun Microsystem and was later bought by Oracle.
  • The first major JDK or Java development kit was released in 1996; it is more than two decades.
  • Android is based on Java, and the Android SDK also uses the technology. Android is one of the most widely used development platforms.
  • Java has no concept of pointers, unlike its predecessors.
  • Unlike what most people think, Java is a programming language, and it should not be confused with JavaScript, which is a scripting language.
  • Java has maintained its supremacy in the development world.

The different editions of Java Platforms


Now let's start understanding the editions of the Java platform.


  1. J2SE (Java Platform, Standard Edition)

Java Platform Standard Edition is known as Core Java and is the most basic and standard version of Java. It is the purest form of Java and is the foundation of all the other editions. It is the oldest version and contains a variety of general-purpose APIs, including Java.Lang, Java.util, etc. There are also many special-purpose APIs available in this edition of Java.

The Java development services are targeted towards using the J2SE version to create applications for desktop environments. It also consists of all the basics of the Java language, such as the primitive data types, arrays, streams, variables, String Java database connectivity, and more. It gives you the amazing features that enhance a developer's experience while coding and provides them the much-needed ease. This is the standard for which all the other editions came out and branched themselves as the development needs evolved.

If you have some basic knowledge of development, you must be known of JVM, which developers widely love, giving them the ability to use it in numerous applications.

  1. J2ME (Java Platform, Micro Edition)

This version is used for the applications that run on the embedded system, smartphones, and small devices. There are many reasons for that, mostly because it limits the processing power, battery limitations, small display, etc. In a way, it was built for developing apps for small devices.

Also, the J2ME apps help in using web compression technologies, which also reduce network usage and also offer cheap internet accessibility.

J2ME uses many libraries and APIs of J2SE and many of its own. The aim of this edition is to work on the mobiles, wireless devices, and set-top boxes, etc. There is a chance that you would have used an app over the Symbian OS, the old Nokia phones, for example.

Most of the apps developed for the phone were also built on the J2ME platform only, the .jar apps on the Nokia app store; this was before smartphones made their way into the market.

  1. J2EE (Java Platform, Enterprise Edition)

The enterprise version of Java is widely used and is more versatile than any other version of Java. It is used in the development of web services, networking apps, server-side scripting, and also other various types of web-based applications.

J2EE is the community-driven edition. There are many technology experts that contribute to the development of the technology. The edition of Java has eased the problems of a custom software development company. J2EE users many components of J2SE and has many new features of its own Servlets, JavaBeans, Java Message Services and adds a whole new level of functionalities to the language.

J2EE uses HTML, CSS, JavaScript, etc., which are widely used by a custom software development company to build web services and web pages. It is also one of the most widely accepted development standards.

There are many languages like .net and PHP, but what they lack is versatility, compatibility, and security features. These features distinguish the technology from other technologies and provide it an upper hand in the competition. Not many languages offer you that feasibility.

Due to its sheer superiority in the development environment, the edition is widely used in the development community and is known as a versatile, web-friendly language.

Other variants of Java

  1. Java Card

Apart from these three versions, there was another Java version released Java Card. The edition is targeted to run applets smoothly and securely on similar technology and smart cards. It is known for its portability and security.

  1. JavaFX

JavaFX is another edition of Java technology; it is now merged with J2SE (Standard Edition) 8 and is mainly used for creating the rich GUI or graphic user interface in Java-based applications.

The version is replaced by Swing and is a standard GUI library. It is supported by both desktop environments as well as web browsers.

  1. Personal Java

Personal Java is another must-know version of Java. It was not deployed much as the function was fulfilled by the further versions of J2ME. It is made to support the World Wide Web and Java applets, including consumer electronics.

Personal Java was also used for embedded systems and mobile but was discontinued in its earlier stage.
