Java Developer Roadmap

This repository provides a structured organization for learning and delving deeper into Java development, following the roadmap available at roadmap.sh/java. The structure is divided into main topics, each with code examples, commented explanations, and a final project that integrates the concepts learned.

Repository Structure

• 1. Java Fundamentals

  • Basic structure of a Java program
  • Syntax, variables, and data types
  • Flow control (if/else, loops)
  • Commented examples

• 2. Object-Oriented Programming (OOP)

  • Classes and objects
  • Inheritance, polymorphism, encapsulation
  • Interfaces and abstract classes
  • Commented examples

• 3. Data Structures and Collections

  • Arrays, lists, maps, sets
  • Iterators and streams
  • Commented examples

• 4. File Handling and I/O

  • Reading and writing files
  • Streams and buffers
  • Commented examples

• 5. Database Connectivity

  • JDBC and ORM (Hibernate, JPA)
  • Basic SQL queries
  • Commented examples

• 6. Web Development with Java

  • Servlets and JSP
  • Frameworks (Spring Boot)
  • REST APIs
  • Commented examples

• 7. Tools and Best Practices

  • Maven and Gradle
  • Testing with JUnit
  • Logging with Log4j or SLF4J
  • Commented examples

Final Project

A practical project integrating the topics above, such as a task management system. The project will include:

• A simple user interface
• Backend with Spring Boot
• Relational database
• Automated tests

How to Use This Repository
