10 Notable Differences Between Java and J2EE

Filed in Technology by on June 7, 2021

Difference Between Java and J2EE: Java is a programming language, while J2EE is a computing platform. Java requires J2EE and J2EE is constructed on Java. The platform is what allows the software to run. When it comes specifically to J2EE, it supports HTML, applications, and applets.

About Java

Java is basically everywhere – from web applications to websites, from laptops to datacenters, game consoles to supercomputers, from desktops to mobile phones, almost everywhere. In fact, almost every native Android application comes pre-built with Java.

Java was initially conceived by James with the aim to create software to be embedded in consumer electronic devices such as remote controls, microwaves, etc. The idea was to develop an architecture-neutral language that would work on different environments on a variety of CPUs, which ultimately gave birth to Java.

About  J2EE

This was originally known as Java 2 Platform, Enterprise Edition, which was later changed to Java Platform, Enterprise Edition (Java EE). This is one of the three computing platforms released by Sun Microsystems which was later acquired by Oracle Corporation. The other two platforms are Java Standard Edition (Java SE) and Java Micro Edition (Java ME).

J2EE consists of a set of APIs, services, and protocols that provide the functionality to develop multi-tiered web-based applications. It includes several technologies that extend the functionality of the Java SE APIs, such as Servlets, Connectors, Enterprise JavaBeans, etc.

It’s mainly used for applications that run on servers and accessible through browsers like Chrome, Firefox, etc. It’s also used for developing web applications over the World Wide Web by creating standardized modular components to handle many aspects of programming.

The J2EE architecture provides services to simplify the common challenges faced by developers while developing modern applications, thereby making it easier to implement industry-standard design patterns for greater efficiency and reliability.

Differences between Java and J2EE

Application of Java and J2EE

Java is robust and platform-independent, which means the compiled code can be executed on any platform running a Java Virtual Machine (JVM). It is written once and runs anywhere because of the bytecode which can run on different operating systems which makes it suitable for websites, servers, mobile phones, embedded systems, etc.

J2EE, on the other hand, provides an architecture-neutral environment to develop large-scale enterprise applications.

Components in Java and J2EE

The three main components of Java language are Java Virtual Machine (JVM), Java Development Kit (JDK), and Java Runtime Environment (JRE). Each component works in conjunction with the other to simplify software development. J2EE, on the other hand, holds Servlets and JavaServer Pages (JSPs), along with Enterprise JavaBeans (EJBs) and Java Database Connectivity (JDBC).

A platform for Java and J2EE

It is a high-level class-based programming language that is commonly used to develop and deliver content on the web. However, it’s a simplified version of C++ designed to run on all JVM-compliant platforms irrespective of the architecture.

J2EE is one of the core technologies of Java used for developing server applications such as websites and web applications.

Terminology of Java and J2EE

The name was first used by Sun Microsystems to refer to the Java Standard Edition (Java SE). It’s a widely-used programming language that derives much of its syntax from C and C++ with fewer implementation dependencies. J2EE is a collection of Java APIs owned by Oracle Corporation used to write server-side enterprise applications.

Key Differences Between Java vs Java EE

1. Java SE is the core Java programming language, however, the Java EE platform is built on top of the SE platform.

2. SE defines everything from the basic types and objects of the Java programming language, however, it provides all core functionalities. The Java EE platform provides an API and runtime environment for developing and running large-scale applications.

3. Java SE platform consists of a virtual machine, development tools, deployment technologies, and other libraries commonly used in Java. Java EE consists of Enterprise JavaBeans, Java Server Pages, Servlets.
