Core Java is the part of Java programming language which is used for creating or developing a general purpose application. Java is a programming language, whereas Core Java is a computing platform. Core Java is the collection of libraries rather than just the programming language.


Java Platform Standard Edition (Java SE) is Core Java and it is the most basic version of Java which sets the foundation for all other editions of Java plus a set of related technologies such as CORBA, Java VM, etc. It is the most widely used platform based on the concept of OOP and is commonly used for development of portable desktop applications.


Core Java is the purest form of Java mainly used for the development of general desktop applications. It is the subset of Java SE technologies which consists of both general-purpose APIs and special-purpose APIs. It provides the core functionality of Java with a deep knowledge of the Java language itself.
