Full Stack Java

A Full Stack Java course in a computer training institute typically covers both front-end and back-end development using Java technologies, alongside essential web development skills. Here’s a breakdown of what such a course might include:

1. Front-End Development

  • HTML/CSS: The structure and styling of web pages.
  • JavaScript: Adding interactivity to websites.
  • Front-End Frameworks:
    • React.js or Angular: These modern JavaScript frameworks/libraries are often taught for building dynamic user interfaces.
    • Bootstrap: CSS framework for responsive design.
  • Version Control (Git/GitHub): Managing code versions and collaborating with others.

2. Back-End Development

  • Core Java: Understanding the fundamentals of the Java language, object-oriented programming, and essential Java libraries.
  • Java EE (Enterprise Edition) or Spring Framework:
    • Building enterprise-level applications.
    • Spring Boot: For rapid application development.
    • JSP/Servlets: Java-based server-side technologies.
    • RESTful Web Services: Creating APIs using Java.
  • Database Management:
    • SQL: Working with relational databases like MySQL or PostgreSQL.
    • JPA/Hibernate: Java Persistence API for ORM (Object Relational Mapping).

 

 
 

3. Full Stack Concepts

  • Integration of Front-End and Back-End: Understanding how to connect the user interface with the server-side logic.
  • Deployment: Deploying web applications on servers like Apache Tomcat, and working with cloud platforms such as AWS.
  • Microservices: Introduction to microservices architecture (if covered).

4. DevOps (Optional but often included in advanced courses)

  • CI/CD: Continuous Integration and Continuous Deployment pipelines.
  • Containerization: Using tools like Docker.
  • Monitoring and Testing: Understanding tools like JUnit for testing and tools for monitoring applications.

5. Project Work

  • The course often includes project work where students build a fully functional web application integrating the front-end, back-end, and database.

  • Tools & Technologies Covered:
  • Java: Core and Advanced Java
  • Spring Framework: Spring Boot, Spring MVC, etc.
  • JSP/Servlets
  • JavaScript Frameworks: React.js or Angular
  • HTML5/CSS3: Web page structure and design
  • Database: MySQL, PostgreSQL, MongoDB
  • Version Control: Git, GitHub
  • Servers: Apache Tomcat
  • Others: Docker, Maven, Jenkins (in advanced courses)

A Full Stack Java course prepares students to develop end-to-end web applications, starting from creating a user interface to designing back-end systems. It’s a valuable skill set for developers aiming to work on both client-side and server-side technologies.Best software training institute in Hayathnagar.

What is the purpose of Maven or Gradle in a full-stack Java project?

They are build automation tools that manage project dependencies, build processes (compilation, testing, packaging), and project structure, ensuring consistency across the development team in Hyderabad.

Briefly explain the difference between сервлет (Servlet) and a Spring Controller.

A Servlet is a fundamental Java class that handles client requests and server responses in web applications. A Spring Controller is a higher-level abstraction built on top of Servlets (or other technologies), providing more features like request mapping, data binding, and MVC integration, simplifying web development in frameworks like Spring Boot popular in Hyderabad.

What is CORS, and why is it important in full-stack Java development, especially when the front-end and back-end run on different ports or domains (common in modern development)?

CORS (Cross-Origin Resource Sharing) is a security mechanism that browsers implement to restrict web pages from making requests to a different domain than the one that served 1 the web page. It’s crucial in full-stack apps in Hyderabad where a React/Angular front-end (running on localhost:3000, for example) needs to communicate with a Java Spring Boot back-end (running on localhost:8080), preventing unauthorized cross-domain requests.

What are some common ways to handle authentication and authorization in a full-stack Java application?
  • Authentication: Verifying the user’s identity (e.g., using username/password, JWT tokens, OAuth 2.0).
  • Authorization: Determining what resources and actions an authenticated user is allowed to access (e.g., role-based access control). JWT (JSON Web Tokens) are a popular stateless approach often used in modern full-stack applications in Hyderabad.
