JAVA is a programming language and computing platform, while J2EE (Java 2 Platform, Enterprise Edition) is a set of specifications extending JAVA for enterprise-level applications.
JAVA vs. J2EE

Key Differences

JAVA is a versatile programming language known for its portability across platforms, due to its principle "write once, run anywhere". On the other hand, J2EE, built on top of JAVA, focuses on simplifying enterprise applications by providing a set of standardized, modular components, and a set of services to use those components.

JAVA forms the core of many computing applications, from mobile applications to web and desktop applications, emphasizing its flexibility and wide use. J2EE extends these capabilities specifically for enterprise needs, offering robust and scalable solutions for large-scale applications such as banking systems and e-commerce websites.

JAVA is generally used for general-purpose programming, providing APIs for various activities like networking, security, XML processing, and more. J2EE, however, is tailored for developing distributed, multi-tiered enterprise applications, providing specialized APIs like Java Message Service (JMS), JavaMail, and Java Transaction API (JTA).

In terms of performance, JAVA's efficiency is notable in small to medium-sized applications. J2EE, while powerful for enterprise solutions, can be more resource-intensive and requires a more detailed approach to performance optimization for large-scale deployments.

JAVA

An object-oriented computer programming language, derived largely from C++, used widely for design and display of web pages on the world-wide web. It is an interpreted language, and has been suggested as a platform-independent code to allow execution of the same progam under multiple operating systems without recompiling. The language is still (1997) under active development, and is evolving.
