Modular Programming in Java is a way to structure your code into independent, reusable modules to improve maintainability, scalability, and readability. It became a first-class concept in Java 9 with the introduction of the Java Platform Module System (JPMS).
In Java, a module is a self-contained group of packages, classes, and resources. It declares:
What it exports (makes available to other modules).
What it requires (dependencies on other modules).

This file is the heart of a Java module.
Example:
+91 8179191999 
+91
8179191999
module com.example.myapp {
requires java.sql;
requires com.example.utils;
exports com.example.myapp.api;
}
requires = imports another module.
exports = makes packages visible to other modules.
Only exported packages are accessible outside the module. The rest is hidden, helping reduce tight coupling.
Improved maintainability: Easier to understand and test smaller parts.
Better encapsulation: Internal APIs stay hidden.
Faster startup: JVM can optimize module loading.
Reliable dependencies: Catches missing modules at compile-time.
Example Structure
myapp/
├── module-info.java
├── com/
│ └── example/
│ └── myapp/
│ └── Main.java
Build Tools: Maven and Gradle now support modules.
IDEs: IntelliJ IDEA and Eclipse support module-aware projects.
Not backward compatible with Java 8 and earlier.
Requires planning your package structure and visibility carefully.
Can be overkill for small projects.
Use it if:
You're working on large or enterprise-scale applications.
You want strong encapsulation and dependency management.
You're targeting Java 9+ and want better tooling and performance.

Node.js has revolutionized modern web development, impacting even full-stack Java applications in significant ways. Traditionally, Java has been the primary choice for enterprise-level applications due to its robustness and scalability. However, with the emergence of Node.js, developers have found a way to integrate its asynchronous, event-driven capabilities into full-stack Java applications, improving performance and development speed.
Java for Backend + Node.js for API Development: Java is widely used for core business logic, while Node.js can be employed to build lightweight RESTful APIs, facilitating faster communication between client and server.
Single Language Across the Stack: With Node.js and JavaScript-based front-end frameworks like React or Angular, developers can maintain a unified JavaScript ecosystem while leveraging Java for critical backend components.
Asynchronous, Non-Blocking I/O Model: Unlike traditional multi-threaded Java applications, Node.js operates on an event-driven architecture, enabling high-speed execution of concurrent tasks without performance bottlenecks.
Microservices Integration: Java-based monolithic applications can be gradually transitioned into microservices architecture using Node.js, improving scalability and maintainability.
Node.js supports rapid prototyping, making it an excellent tool for developing and testing small modules of a Java-based application before full-scale implementation.
NPM (Node Package Manager) provides a vast ecosystem of open-source packages, allowing Java developers to integrate third-party libraries efficiently.
WebSockets in Node.js allow seamless real-time communication, making it ideal for features like live chat, notifications, and collaborative tools in full-stack Java applications.
Event-driven architecture in Node.js complements Java-based applications by handling real-time data processing more efficiently.
Node.js simplifies the development of DevOps tools, making CI/CD pipelines more efficient when deploying Java applications.
Lightweight Node.js-based containerized services work well with Docker and Kubernetes, streamlining deployment alongside Java-based microservices.
The impact of Node.js on full-stack Java development is significant, offering complementary advantages in API development, microservices integration, real-time processing, and DevOps automation. Instead of replacing Java, Node.js enhances full-stack Java applications, enabling better performance, flexibility, and development speed in modern web applications.

How to Become A Full Stack Web Developer?
Here I am going to discuss the few important steps and some related courses which will definitely help you to become a full stack Java developer. To become a full stack Java developer a student should have to focus according to below mentioned points and need to prepare accordingly.
To become a Java Full stack developer, one should be aware about both front end and the backend development process for developing the application.
At a bare minimum, one should know at least a one frontend framework which can be developed using the HTML, CSS and Java script.
If you are comfortable with the Angular or React then definitely it will add an extra mileage to your career.
In addition with the front end concept you should be comfortable with the backend framework like Spring or Spring Boot also.
To develop the backend application part we can choose the technology like Servlet, JSF, Web-logic etc.
But if we are going for choosing the framework as a choice then the best combination will be Spring Boot + Angular or Spring Boot + React.
But if you know Java, JSP, and Spring, then also you are qualified as a full-stack Java developer.
