Core Skills for Java Full Stack Development

1. Front-End Technologies (Client-side development)

   • HTML: The backbone of web development, used to structure content on the web.
   • CSS: Used for designing and laying out web pages, including styling.
   • JavaScript: The scripting language that allows interaction with the user and dynamic content rendering on the browser.
   • Frameworks/Libraries:
     • React: A JavaScript library for building user interfaces, especially single-page applications (SPAs).
     • Angular: A platform and framework for building client-side applications with HTML, CSS, and JavaScript.
     • Vue.js: Another framework for building user interfaces, focused on simplicity and flexibility.
   • AJAX: A technique for sending and receiving data asynchronously without refreshing the webpage.
   • Bootstrap: A front-end framework that helps build responsive websites and applications quickly.

2. Back-End Technologies (Server-side development)

   • Java: The core language for back-end development in Java Full Stack. Java is used to handle business logic, data processing, and the server-side application flow.
   • Spring Framework: A comprehensive framework that provides support for building Java-based enterprise applications. Key components:
     • Spring Boot: Simplifies the process of setting up and configuring Java applications, making it ideal for microservices.
     • Spring MVC: A framework for building web applications, providing support for RESTful APIs and web services.
     • Spring Data JPA: Helps with database interaction, providing an abstraction layer for working with databases.
     • Spring Security: A robust framework for securing Java applications, including authentication and authorization mechanisms.
   • JSP (JavaServer Pages): A technology used to build dynamic web pages, combining HTML with Java code for dynamic content generation.
   • RESTful APIs: Java-based REST APIs are often used to handle communication between the front-end and back-end systems.

3. Databases (Data storage and management)

   • SQL Databases: Java Full Stack developers typically work with relational databases like:
     • MySQL
     • PostgreSQL
     • Oracle DB
   • NoSQL Databases: Some Java Full Stack developers may also use NoSQL databases, such as:
     • MongoDB
     • Cassandra
   • Hibernate: An Object-Relational Mapping (ORM) tool that simplifies database interaction by mapping Java objects to database tables.

4. Version Control & Collaboration

   • Git: A distributed version control system that allows developers to manage code changes and collaborate with teams.
   • GitHub/GitLab/Bitbucket: Platforms to host Git repositories, enabling version control, collaboration, and code reviews.

5. Development and Build Tools

   • Maven: A build automation tool that simplifies the process of building, packaging, and managing dependencies in Java projects.
   • Gradle: Another build automation tool, often preferred in modern Java projects for its flexibility and performance.
   • Jenkins: A tool used for continuous integration and continuous deployment (CI/CD), automating the build and deployment process.

6. Testing Frameworks

   • JUnit: A widely used framework for unit testing Java applications.
   • Mockito: A mocking framework used for testing Java applications, enabling the creation of mock objects.
   • Selenium: A framework for automating web browsers to test front-end functionality.
   • TestNG: A testing framework designed to cover a broader range of testing needs, including unit, integration, and functional testing.

7. Cloud Platforms & Deployment

   • AWS: Amazon Web Services, used to host and scale Java applications on the cloud.
   • Azure: Microsoft’s cloud platform for deploying, managing, and scaling Java applications.
   • Heroku: A platform as a service (PaaS) that enables easy deployment of Java applications.
   • Docker: A tool for containerizing Java applications, allowing them to be run consistently across different environments.

8. DevOps Tools

   • Docker: Used for containerizing applications to streamline development and deployment processes.
   • Kubernetes: An open-source container orchestration system that automates the deployment and scaling of containerized applications.
   • CI/CD: Tools like Jenkins, GitLab CI, or CircleCI are used to automate testing, building, and deploying Java applications.

Typical Workflow of a Java Full Stack Developer:

1. Frontend Development:

   • The developer creates the user interface using HTML, CSS, and JavaScript (along with frameworks like React or Angular).
   • Data is fetched from the back-end using AJAX calls or RESTful APIs.
   • The front-end is made responsive and interactive, ensuring a seamless user experience.

2. Backend Development:

   • The developer builds REST APIs or web services using Java and the Spring Framework (e.g., Spring Boot).
   • The back-end handles requests, processes data, and interacts with databases (using JPA or Hibernate for SQL databases).
   • Security (authentication, authorization) is implemented using Spring Security.

3. Database Integration:

   • The developer integrates databases (either SQL or NoSQL) into the back-end system, ensuring smooth data storage and retrieval.
   • Data models are defined using JPA/Hibernate, simplifying interaction between the Java application and the database.

4. Testing & Debugging:

   • Unit tests are written for the back-end logic using JUnit or Mockito.
   • Front-end testing is done using frameworks like Selenium for browser-based testing.
   • The application is debugged, and performance is optimized.

5. Deployment:

   • Once the application is built and tested, it is deployed using tools like AWS, Docker, or Heroku.
   • The deployment process may involve using CI/CD pipelines to automate builds, testing, and deployment.
