✨ What’s Inside

Java-Learning is my personal codebase for mastering core Java concepts—from object-oriented principles to algorithmic problem solving and app scaffolding. Each module lives alongside samples and exercises so you can follow the same learning path, experiment with code, and build confidence.

🛠️ Features & Topics Covered

• ☝️ Core Java: Syntax, OOP pillars (Encapsulation, Inheritance, Polymorphism, Abstraction), exceptions
• 🔄 Data Structures & Algorithms: Arrays, Lists, Stacks, Queues, Trees, Graphs, Sorting & Searching
• 🏗️ Design Patterns: Singleton, Factory, Observer, Strategy
• 🌐 App Foundations: Project scaffolding, package organization, build scripts
• 🧩 Hands-On Exercises: Leetcode-style challenges with runnable code
• 📚 Documentation: Inline comments, design notes, and conceptual write-ups

🚀 Getting Started

Prerequisites

• Java JDK 11 or higher
• IntelliJ IDEA or Eclipse (optional)
• Git (for cloning)

Clone & Open

git clone https://github.com/Kratugautam99/Java-Learning.git
cd Java-Learning

• IntelliJ/Eclipse: Import the project as a Maven/Gradle module or open the existing .iml.
• Command Line: Compile and run via javac/java (see below).

⚙️ Build & Run

Via IDE

1. Open src/Kratu/company in your IDE.
2. Right-click any *.java file with a main() method.
3. Select Run to execute.

Via Command Line

# Compile all classes
javac -d out src/Kratu/company/**/*.java

# Run a specific program (example: Main)
java -cp out Kratu.company.Main

📝 Notes & Documentation

• CustomDocs/ houses design diagrams, UML sketches, and deeper concept write-ups.
• Java_Complete_Notes.7z contains my full set of study notes—extract locally to review them offline.
