"Advanced Java" typically refers to an extended set of features and APIs beyond the core Java SE (Standard Edition) platform. It encompasses various technologies and frameworks used for enterprise-level application development, web development, and more complex functionalities.

Here are some key topics and components often associated with Advanced Java:

1. Java EE (Enterprise Edition): Advanced Java often involves Java EE, now known as Jakarta EE, which is a set of specifications providing enterprise-level functionalities like distributed computing, web services, and scalability. Jakarta EE includes APIs for Servlets, JSP (JavaServer Pages), JPA (Java Persistence API), EJB (Enterprise JavaBeans), and more.

2. Servlets and JSP: Servlets are Java programs that extend the capabilities of servers to handle client requests. JSP is a technology that helps developers embed Java code in HTML files to create dynamic web pages.

3. JDBC (Java Database Connectivity): JDBC allows Java applications to interact with databases by providing a standard interface to connect and execute SQL queries. It enables connectivity to various databases, facilitating data retrieval, storage, and manipulation.

4. JavaServer Faces (JSF): JSF is a Java-based web application framework used for building component-based user interfaces. It simplifies the development of web applications by providing reusable UI components.

5. Enterprise JavaBeans (EJB): EJB is a server-side component architecture used for building scalable, distributed, and transactional enterprise applications. It provides services such as security, transaction management, and persistence.
