✨ 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. SpringBoot Backend Files are also Added.

🛠️ 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).
• Spring Boot: The Backend Spring Boot Folders have their own README.md refer it.

⚙️ 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
