A Java web Full Stack developer is a professional who specializes in developing web applications using the Java programming language for both front-end and back-end development. This means they have expertise in a combination of technologies and tools that enable them to build complete web solutions. Here’s an overview of what a Java web Full Stack developer does and the technologies they commonly work with:

Front-End Development:

1. HTML/CSS: Like any web developer, a Java Full Stack developer should have a strong understanding of HTML for structuring web content and CSS for styling web pages.
2. JavaScript: JavaScript is used for adding interactivity and dynamic behavior to web pages. Knowledge of JavaScript libraries and frameworks like React, Angular, or Vue.js is beneficial.

Back-End Development:

1. Java: The Java programming language is the primary tool for back-end development. Java is known for its versatility, reliability, and performance. Developers use Java to build server-side components and handle business logic.
2. Spring Framework: The Spring Framework is a popular choice for building Java-based web applications. It provides a comprehensive set of features for developing robust and scalable applications, including Spring Boot for simplifying project setup.
3. Database Integration: Java Full Stack developers work with various databases, including relational databases like MySQL, PostgreSQL, or Oracle, and NoSQL databases like MongoDB or Cassandra.
4. API Development: Building RESTful or GraphQL APIs to enable communication between the front-end and back-end components of the application. Java provides libraries like Spring MVC for creating APIs.
5. ORM (Object-Relational Mapping): Using ORM tools like Hibernate to simplify database interactions by mapping Java objects to database tables.
6. Server Deployment: Deploying Java web applications on web servers like Apache Tomcat, Jetty, or using cloud platforms like AWS, Azure, or Google Cloud.
