Java Full Stack Developer Roadmap
Becoming a Java Full Stack Developer involves mastering both front-end and back-end development, along with building knowledge in databases, DevOps, and system design. This roadmap will guide you step-by-step through the skills, tools, and technologies you need to master.
Phase 1: Learn the Fundamentals
1.1 Core Programming Concepts
Before jumping into Java, it’s essential to understand fundamental programming concepts.
- Basics of Programming: Variables, data types, control structures (if-else, loops), and functions.
- Object-Oriented Programming (OOP): Understand the four pillars (Encapsulation, Inheritance, Polymorphism, and Abstraction).
Phase 2: Master Java
2.1 Core Java
- Basic Java Syntax: Learn the basic syntax, variables, operators, and control structures.
- OOP in Java: Classes, objects, constructors, inheritance, interfaces, and polymorphism.
- Collections Framework: Understand Java collections like List, Map, Set, and their implementations.
- Multithreading: Learn about creating threads, thread synchronization, and concurrent programming.
- Exception Handling: Try-catch blocks, custom exceptions.
- File I/O: Learn how to read and write files in Java.
Resources:
- Book: “Head First Java” by Kathy Sierra.
- Online: Oracle’s official Java tutorials, Udemy, Coursera.
2.2 Advanced Java
- Generics: Parameterized types, working with type safety.
- Streams and Lambda Expressions: Understand how to work with streams for functional programming.
- JVM Internals: Understand how the Java Virtual Machine works, including garbage collection and memory management.
Phase 3: Database Management
3.1 Relational Databases (SQL)
- SQL Basics: Learn to create, read, update, and delete data using SQL.
- Joins and Aggregations: Understand how to combine data from multiple tables and perform data summarizations.
- Database Design: Learn about normalization, indexing, and relationships (one-to-one, one-to-many, many-to-many).
Tools:
- MySQL or PostgreSQL: Install and work with a relational database.
3.2 NoSQL Databases
- MongoDB: Learn how to work with NoSQL databases to handle unstructured or semi-structured data.
Phase 4: Back-End Development (Java Frameworks)
4.1 Java Servlets and JSP
- Java Servlets: Learn how to handle HTTP requests/responses using Servlets.
- JSP (Java Server Pages): Learn how to build dynamic web pages using Java code embedded in HTML.
4.2 Spring Framework
Spring is a powerful Java framework widely used for building enterprise-level applications.
- Spring Core: Dependency Injection (DI), Inversion of Control (IoC) principles.
- Spring Boot: Build stand-alone Spring applications with minimal configuration. Master the following:
- Creating RESTful APIs using Spring Boot.
- Handling HTTP requests and responses.
- Using annotations like @RestController, @RequestMapping, @GetMapping, etc.
- Spring Data JPA: Work with databases using ORM (Object-Relational Mapping). Learn how to use JPA and Hibernate.
- Spring Security: Implement security features like user authentication and authorization.
- Spring MVC: Understand how to build web applications with Spring’s Model-View-Controller pattern.
Resources:
- Book: “Spring in Action” by Craig Walls.
- Online: Spring’s official documentation, Udemy courses.
Phase 5: Front-End Development
5.1 Core Front-End Technologies
- HTML: Structure of web pages, elements, attributes, and forms.
- CSS: Styling web pages with CSS, including layouts (Flexbox, Grid), and responsive design using Bootstrap.
- JavaScript: Core programming language for front-end development. Learn how to manipulate the DOM, work with events, and handle asynchronous operations using promises and async/await.
5.2 Front-End Frameworks
- React.js: Learn how to build dynamic, component-based front-end applications using React.
- Components, JSX, props, and state management.
- Working with hooks and handling forms.
- Consuming APIs and rendering data on the UI.
- Angular: If you prefer Angular, learn about components, services, dependency injection, and how to work with Angular’s template syntax.
- Vue.js: A lightweight, approachable alternative to React and Angular for building front-end interfaces.
Resources:
- Courses: Udemy or FreeCodeCamp for hands-on practice with React, Angular, or Vue.
Phase 6: Build RESTful APIs and Web Services
6.1 REST API Design
- HTTP Methods: GET, POST, PUT, DELETE, PATCH.
- JSON: JavaScript Object Notation is the format used for API requests and responses.
- API Design Principles: Learn about versioning, statelessness, and RESTful principles.
6.2 API Implementation with Spring Boot
- Build a RESTful API using Spring Boot.
- Understand how to handle requests and responses, including validation and error handling.
- Integrate with databases using Spring Data JPA.
Phase 7: Version Control and Collaboration
7.1 Git and GitHub
- Git: Learn how to initialize repositories, stage changes, make commits, and use branching strategies.
- GitHub: Host your projects on GitHub and collaborate with others using pull requests and code reviews.
Phase 8: Testing
