By the end of Part 1, you will be able to understand basic Java programs, solve logical problems, and feel confident navigating Java’s syntax and structure.

Part 2: Object-Oriented and Advanced Java Concepts

Objective: Dive into object-oriented programming and explore advanced topics essential for modern Java development.

· Grasp the pillars of OOP: Encapsulation, Inheritance, Polymorphism, and Abstraction.

· Create and manage classes, objects, methods, constructors, and access control.

· Understand Exception Handling for writing robust and error-free code.

· Explore the Java Collections Framework: Lists, Sets, Maps, and data processing with Iterators and Streams.

· Handle file input/output, serialization, and understand file manipulation techniques.

· Learn about Multithreading and Concurrency, including the use of Executors and Synchronization.

· Introduction to functional programming with Lambda Expressions and working with Streams.

By the end of Part 2, you will be equipped to understand modular, efficient, and multi-threaded Java applications with a professional coding style.

Part 3: Java Development Tools, Real-World Applications & Capstone Project

Objective: Transition from learner to developer by building real-world applications and mastering professional tools.

· Get hands-on with Build Tools like Maven and Gradle for managing Java projects.

· Introduction to Version Control using Git.

· Develop database-driven applications using JDBC.

· Create graphical interfaces using JavaFX.

· Write Unit Tests with JUnit to ensure code reliability.

· Understand how to debug applications effectively.

· Work on real-world projects like:

o Online Quiz Application

o Real-Time Chat Application using Sockets

o Library Management System

o Banking System with database integration

· Capstone Project: Develop, document, and present a full-scale Java application demonstrating all major concepts learned.

By the end of Part 3, you will have built an impressive project portfolio, understood industry practices, and gained the confidence to step into the professional Java development world.

Online Quiz Application in Java

To develop a real-world Java application for an Online Quiz system, we’ll create a simple console-based Java application that allows users to take a quiz, view results, and interact with a set of questions.

Real-World Java Chat Application using Sockets

To develop a Chat application using Java Sockets to create a server-client interaction. In this application: Server listens for incoming client connections, Client connects to the server and exchanges messages with other clients, Both client and server will use Socket Programming in Java to communicate over a network.
