Introduction

This repository is designed for developers who have a basic understanding of Java and want to explore advanced topics and enterprise-level development using Java. Through a series of guided examples and hands-on projects, you will gain practical experience with various advanced Java features and J2EE technologies.

Prerequisites

To get the most out of this repository, you should have:

• A solid understanding of Java fundamentals (syntax, OOP concepts, exception handling, etc.)
• Familiarity with basic Java development tools (JDK, IDEs like IntelliJ IDEA or Eclipse)
• Basic knowledge of web development concepts

Topics Covered

Advanced Java Concepts

1. Collections Framework

   • Advanced usage of collections (e.g., custom comparators, sorting, and filtering)
   • Understanding and implementing advanced data structures (e.g., trees, graphs)

2. Concurrency

   • Multithreading and parallel processing
   • Synchronization, locks, and thread-safe collections
   • Executors framework and Fork/Join framework

3. Input/Output (I/O)

   • Advanced file I/O operations (e.g., NIO, file channels)
   • Serialization and deserialization
   • Network programming (e.g., sockets, NIO networking)

4. Generics

   • Advanced usage of generics (e.g., bounded types, wildcards)
   • Generic methods and classes
   • Type inference and type erasure

5. Lambdas and Streams

   • Functional programming in Java
   • Stream API for data processing
   • Parallel streams and performance considerations

6. Reflection and Annotations

   • Using reflection for dynamic class loading and method invocation
   • Creating and processing custom annotations

J2EE (Java Enterprise Edition)

Java Enterprise Edition (J2EE) is a set of specifications that extend the Java Standard Edition (Java SE) to provide a robust and scalable environment for building enterprise-level applications. J2EE includes APIs for developing multi-tiered, distributed, and web-based applications.

1. Servlets and JSP

   • Creating and managing servlets
   • Using JavaServer Pages (JSP) for dynamic web content
   • Session management and cookies

2. Enterprise JavaBeans (EJB)

   • Stateless and stateful session beans
   • Message-driven beans
   • Container-managed transactions

3. Java Persistence API (JPA)

   • Object-relational mapping (ORM) with JPA
   • Entity lifecycle and entity relationships
   • Querying with JPQL and the Criteria API

4. Java Message Service (JMS)

   • Messaging models (point-to-point and publish/subscribe)
   • Creating and consuming JMS messages
   • Configuring message-driven beans

5. JavaServer Faces (JSF)

   • Building component-based user interfaces
   • Managed beans and navigation
   • Integration with backend services

6. Web Services

   • Creating RESTful web services with JAX-RS
   • Creating SOAP-based web services with JAX-WS
   • Security and best practices for web services
