It includes topics such as SOAP-based and RESTful web services, XML processing, JSON serialization, and client-server communication.

8. Concurrency and Multithreading: Advanced Java explores advanced topics in concurrency and multithreading, such as synchronization, locks, threads, thread pools, executors, and concurrent data structures. It covers techniques for writing thread-safe and scalable Java applications.

9. Design Patterns: Advanced Java covers design patterns, such as creational, structural, and behavioral patterns, and their application in Java programming. It includes topics such as Singleton, Factory, Adapter, Observer, and Strategy patterns.

10. Java Messaging Service (JMS): JMS is a Java API for messaging between distributed client applications. Advanced Java covers JMS concepts, messaging models (point-to-point and publish/subscribe), message-driven beans, and integration with message brokers such as Apache ActiveMQ or RabbitMQ.
