To many developers who are just getting started, Java is just one language. However, Java is a very rich programming language with different scopes: a core-level java and an advanced-level java. Advanced Java is specifically for senior java developers or those looking into increasing their skillset.

Here are some differences between core and advanced Java.

Core Java Features

  • Developing general purpose applications
  • Needed to develop advanced Java applications
  • Is used in OOP, data types, operators, functions, exception handling, loops, and threading
  • Uses one-tier architecture
  • Covers concepts such as swings, awt, thread concept, classes, and more.

Advanced Java Features:

  • Developing online and mobile applications
  • It only deals with advanced concepts like databases, DOM, networking, etc.
  • It has specific sections like web services, servlets, database connectivity, etc.
  • Uses two-tier architecture
  • Used for web-based applications and enterprise application


Detailed Working of Advanced Java

Unlike core Java, advanced Java comprises particular domains. It’s used to build enterprise-level applications, including apps that run on servers, e.g., web applications. It uses a two-tier architecture such as client-service. The interface layer runs on the client-side while the data layer stores on the server-side.

Advanced Java uses specialized packages that begin with: javax.servlet.somepackage. You’re also required to have additional knowledge of related and advanced concepts and packages, including JSON parsing, XML handling, and REST creation.

Core Java uses Java Standard Edition as its platform, while advanced Java uses Java Enterprise Edition or Java EE. To get a better understanding of advanced Java, you’ll have to be excellent at Core Java concepts such as data types, operators, threading, and exception handling. From here on, you can learn advanced features like database connectivity, JSP, EJB, servlets, web services, and more.


Core Java and Advanced Java both make up the language. While the former is an integral part of the Java language, the knowledge of advanced Java along with it creates better concepts and a complete approach. There’s also no clear distinction between core and advanced Java. Learning advanced Java depends on learning core Java, but both of them combined give Java the power it boasts of.
