Essential Tools for Java Full Stack Developers
Front-End Development (Client-Side)
The Front-End Development includes creating a visual interface of an application. It focuses on designing the user-friendly and interactive web pages.
Major Techniques used includes:-

1. HTML, CSS, JavaScript. Basic building blocks for web-design. These Fundamental Web Technologies are needed to create responsive web applications
2. React.js or Angular. Popular frameworks for building dynamic web applications. React.js is a JavaScript Library for creating simpler UIs with reusable components. Angular is a TypeScript Framework for Enterprise Applications.
3. BootStrap and Material UI. library for responsible Design.
4. TypeScript. A superscript of JavaScript that helps in writing scalable applications.
5. Restful API Integration. Fetching and displaying dynamic data from the backend. Restful API also enables communication between clients and servers. APIs are needed to merge applications and Services. Soap Web Services & GraphQL, again are API development & Testing Tools

Back-End Development (Server-Side)
Back-End business logic, database operations and users are responsible for handling authentication.
Java is a primary language, supported by:-
Java Development Frameworks
Frameworks allow the developers to write robust applications with ease using reusable code and structure. Java Back-End Development includes writing clean, skilled & maintainable codes that interact with database, third-party APIs and other services. Breaking applications in small, managed services for better security and maintenance thus comes in Micro Services Architecture.

1. Spring Boot. A powerful framework to create Rest API and MicroServices. Spring Boot is an open-source system that simlifies some spring-based configurations to enable easier MicroService Development. Spring Boot shuns tedious configurations and allow for faster Java Application Development.
2. Java Servlets and Java Server Pages (JSP). Older Technologies are still used in some applications.
3. Hibernate. Object Relational Mapping (ORM) Tool for managing database connections. Hibernate is an Object-Relational Mapping software that provides access to databases through Java Applications directly without using tedious SQL Queries.
4. Spring Security. Used for authentication & authenticity in web applications.
5. Java Server Faces (JSF). It facilitates web application development using reusable UI Components and therefore Front-End Development becomes simpler.

Coding and Building Tool.
a) Maven and Gradle
b) Eclipse, Intellij IDEA, NetBeans

Version-Control Systems & Collaboration.
a) Git & GitHub
b) GitLab & BitBucket

Data-Base Management.
a) MySql
b) PostgreSQL
c) MongoDB
d) Redis

Logging & Monitoring Tools.
a) Log4j
b) ELK Stack (ElasticSearch, LogStash, Kibana)

Java Developers Testing Tools
Testing is an essential part of software development as it ensures the application works as intended.

1. JUNIT & MOCKITO. Used for writing unit and integration tests.
2. SELENIUM. For automated UI testing.
3. TESTNG. 4.POSTMAN. API testing tool. POSTMAN is a robust API test tool through which developers can send, test and debug API requests.
4. SWAGGER. It is used to design, build and document REST APIs, so that Back-End and Front-End teams can communicate easily.

Devops & Containerization Tools
a) Docker.
Makes deployment and scaling easier.
b) Kubernetes.
It is a container orchestration tools.
c) Jenkins.
It is a CI/CD tool that provides automatic software development pipelines, enabling faster delivery and deployment.
d) CI/CD Pipelines Automating.
Testing and Deployment using Jenkins, GitHub Actions or GitLab CI/CD.
