What is the difference between core Java and Java EE?

Java is an object-oriented programming language and computing platform. It has various libraries, virtual machines, components, and many more. Java has multiple editions, like Java SE, Java EE, and Java ME. Let's understand how core Java differs from Java EE.

Core Java :

• Core Java, also known as Java SE(Java Standard Edition), is the basic foundation of the Java programming language. It is used for building small, single, and desktop applications.

• Java's core functionalities include libraries, syntax, essential input/output, multithreading, and networking. It also consists of many APIs, such as Java. util, Java.io, and Java.lang, and many more.

• It is only used for developing desktop and server-based applications. Core Java has no community and does not provide authentication functionality. It is less complex and more cost-effective.

Java EE :

• Java EE(Java Enterprise Edition) is designed to build large applications such as enterprise applications, distributed applications, secure network applications, and more.

• It includes additional libraries and APIs compared to core Java, such as Java Beans, JPA(Java Persistence API), JAX-RS (Java API for RESTful Web Services), JMS (Java Message Service), and many more. Java EE includes many integrated tools and servers, such as IDE Eclipse or IntelliJ IDEA, as well as servers like Apache Tomcat, WebLogic, JBoss, and more.

• Due to its enormous scope, security, and networking, Java EE is mainly used to design robust and scalable applications. It is used in many sectors, such as eCommerce, healthcare, fintech, CRM, and other industries, to build highly scalable, readable, and secure applications.

Overall, Java Core is the foundation of the Java language, with its essential features and API. Java EE is the extended version of core Java, with many libraries and APIs supported for large-scale applications.
