Advanced Java is everything that goes beyond core Java most importantly beyond the APIs defined in Java Enterprise Edition, including Servlet Programming, Web Services, the Persistence API, etc. It is a Web & Enterprise application development platform that basically follows client and server architecture. 

It is a part of the Java programming language. It is an advanced technology or advanced version of Java specially designed to develop web-based, network-centric, or enterprise applications. It includes the concepts like Servlet, JSP, JDBC, RMI, Socket programming, etc. It is a specialization in a specific domain.

To develop general purpose applications. To develop online application and mobile application. Without Core Java no one can develop any advanced java applications. Advance java is used for web based application and enterprise application

JEE (advanced Java) provides libraries to understand the concept of Client-Server architecture for web-based applications.

We can also work with web and application servers such as Apache Tomcat and Glassfish Using these servers, we can understand the working of HTTP protocol.

Core Java covers some topics like data types, OOP, operators, exception handling, swing, threading, and collections. Advanced Java covers some topics like web services, database connectivity, JSP, Servlets, EJB, etc. Core Java assists a user in building some general-purpose applications
