What is difference between core Java and Java EE?

Terminology of Java and J2EE

Java is a tem given by Sun Microsystems to refer to the Java Standard Edition (Java SE). It’s a widely used programming language which derives much of its syntax from C and C++ with fewer implementation dependencies. J2EE, originally known as Java Enterprise Edition (Java EE), is a collection of Java APIs owned by Oracle Corporation used to write server-side enterprise applications.

Platform for Java and J2EE

Java is a high-level class-based programming language that is commonly used to develop and deliver content on the web. It’s a simplified version of C++ designed to run on all JVM-compliant platforms irrespective of the architecture. J2EE, on the other hand, is one of the core technologies of Java used for developing server applications such as websites and web applications.

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 write once and run anywhere language because of the bytecode which can run on different operating systems, making it a preferred choice for all kinds of platforms such as 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 each 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).

Key difference: Java is a programming language, which has been influenced by the C language. It derives much of its syntax from C and C++, however it has fewer low-level facilities than either. J2EE is a computing platform that is based on the Java programming language. A computing platform allows the developed software to run.
