The Differences Between Java and Java EE
A Java Training Article
A Java Overview
Java is both a platform and a programming language. The Java programming language is a high-level object-oriented programming (OOP) language with a distinct style and syntax. The Java platform refers to a particular environment in which Java programming language applications run. There are different types of Java platforms.
The Java programming language platforms include:
- Java (Java Standard Edition – SE)
- Java ME, (Java Micro Edition) – not used much as Android has taken over here.
- JavaFX and,
- Java EE (Java Enterprise Edition)
Some Java platforms can consist of an application programming interface (API), and a Java Virtual Machine (JVM). A Java API refers to a collection of software components that a developer can use to create other applications or software. A Java Virtual Machine refers to a program, for a particular software or hardware platform, which runs a Java technology application. Depending on the platform that a developer chooses, each Java platform has a VM and an API. The Java programming language has the advantage of being:
- A powerful programming language
- Platform independent
- An environment for ease of development
In this article, let’s look at the differences between Java and Java EE.
Some differences between Java and Java EE
Java offers the core functionalities of Java programing language. Additionally, it defines everything from the basic types of objects of the Java programming language to high-level classes, which are used for database access, security, networking, XML parsing and GUI development. In addition to the core API, the platform consists of deployment technologies, a VM, development tools class libraries and toolkits used in Java applications.
Java Enterprise Edition is a platform-independent and centric environment where developers build and deploy web-based applications. Java EE inherits most components from Java. However, it consists of protocols, APIs, and set of services that offer the functionality of developing both multi-tiered and web-based applications. It simplifies the application development process by decreasing the need for programmer training through the creation of standardized and modular reusable code. In addition, Java EE enables the tier to handle multiple aspects of programming automatically. Enterprise developers usually require Java EE, as writing distributed business applications is not an easy task. Enterprise developers require a high productivity solution that enables them to focus on writing their business logic while having a full range of enterprise-class service upon which to rely.
The Java programming language is designed for use in a distributed environment. It is one of the most popular languages for Android smartphone applications. It is also a favored language for edge devices and IoT development. Although it was designed to look and feel like C++, it is simpler to use than C++ in enforcing an object-oriented programming model. Additionally, it can be used to create complete applications that run on single computers or be distributed among clients and servers in a network. Java is also well-suited to develop applets for use as part of the webpage.
The Java platform is used to develop stand-alone apps. It provides all the required API’s needed to develop traditional applications. On the other hand, Java EE provides developers with the ability to create server-side components that respond to a web-based request-response cycle. These days, most companies are using Java EE for SOAP services (almost a legacy technology at this point), REST services (very much on the rise), asynchronous messaging via JMS, and object-relational mapping via JPA (which grew out of EJB but is more its own domain now).
Some of the notable projects developed using the Java programming language include a variety of open source projects including the Apache Foundation that hosts a number of projects written using Java. These include:
- Big data processing frameworks like Hadoop and Yarn.
- Micro services development platform.
- Integration platforms including Apache Axis, Apache Camel, and Restful web services.
Both Java and Java EE have different benefits. Thus, before starting an application, you should consider the following:
1 – Web or Desktop Application
Java is suitable for desktop applications while Java EE is better used for web applications.
2 – Features
Java EE has different enterprise-wide features like EJB and Servlets. These features make the development process easier. Additionally, Java EE is built on top of Java. Nonetheless, if you are developing a simple application with basic functionalities then Java is probably the better choice.
3 – Security
Java EE applications are multi-tiered, hence providing an additional layer of security and reusability.
