Programming Languages for Java Web Development

Java (Backend)

The backbone of enterprise web development. Java handles business logic, server-side processing, APIs, and integration with databases using frameworks like Spring Boot, Hibernate, and Jakarta EE.

• Spring Boot & Spring MVC
• JPA / Hibernate
• RESTful APIs
• Microservices

HTML (Structure)

HTML defines the structure and layout of web pages. It creates headings, forms, buttons, navigation menus, and connects frontend with backend services.

• Forms & Input Handling
• Semantic Elements
• Templates (Thymeleaf, JSP)

CSS (Design)

CSS controls the look and feel of the website. It ensures responsive design, animations, layouts, and modern UI/UX styling.

• Flexbox & Grid
• Responsive Design
• Bootstrap / Tailwind

JavaScript (Interactivity)

JavaScript makes web applications dynamic by handling user interactions, API calls, form validation, and real-time updates.

• DOM Manipulation
• Fetch / AJAX
• React / Angular / Vue

SQL (Databases)

SQL is used to store, retrieve, and manage application data in relational databases used by Java backend services.

• MySQL
• PostgreSQL
• Oracle DB

Scripting & DevOps

Used for automation, deployment, and environment management in production-ready web systems.

• Bash / Shell
• Docker
• YAML (CI/CD)

Frontend Layer

HTML, CSS, and JavaScript create the user interface and communicate with the backend using HTTP and REST APIs.

Backend Layer

Java processes business logic, handles authentication, manages requests, and interacts with databases using frameworks.

Database Layer

SQL databases store user data, transactions, and system information securely and efficiently.
