+# Lesson 02 Quiz - Java Port
+
+This is a Java port of the Lesson 02 quiz application, originally written in TypeScript. It demonstrates the same quiz functionality using the `codedifferently-instructional` Java library.
+
+## Features
+
+- 11 multiple choice questions covering:
+  - Version control and Git concepts
+  - IDE and development environment topics
+  - Terminal/command line basics
+  - Mac-specific shortcuts
+
+## Prerequisites
+
+- Java 21 or later
+- Gradle (included via wrapper)
+
+## Building and Running
+
+### Build the project
+```bash
+./gradlew build
+```
+
+### Run the quiz
+```bash
+./gradlew run
+```
+
+### Run tests
+```bash
+./gradlew test
+```
+
+## Project Structure
+
+- `app/src/main/java/quiz_java/Lesson2.java` - Main quiz implementation
+- `app/src/main/java/quiz_java/App.java` - Application entry point
+- `app/src/test/java/quiz_java/Lesson2Test.java` - Unit tests
+- `app/build.gradle.kts` - Build configuration
+- `settings.gradle.kts` - Multi-project settings
+
+## Dependencies
+
+This project uses the `codedifferently-instructional` library located at `../../lib/java/codedifferently-instructional/instructional-lib` which provides:
+
+- `AnswerChoice` enum for multiple choice options
+- `MultipleChoiceQuizQuestion` class for question representation
+- `QuizPrinter` class for displaying the quiz
+- `QuizQuestion` base class
+
+## Quiz Questions
+
+The Java implementation contains the same 11 questions as the TypeScript version:
+
+1. **Question 0**: Version control purpose → Answer: B (To keep a record of changes over time)
+2. **Question 1**: Git fork definition → Answer: A (A duplicate copy of a repository that you own and modify)
+3. **Question 2**: Non-Git workflow activity → Answer: D (Write code directly in GitHub)
+4. **Question 3**: Branch merging command → Answer: B (git merge)
+5. **Question 4**: Class IDE → Answer: D (VS Code)
+6. **Question 5**: VS Code environment feature → Answer: C (Dev Containers)
+7. **Question 6**: Non-IDE purpose → Answer: C (Playing music)
+8. **Question 7**: Directory listing command → Answer: B (ls)
+9. **Question 8**: Directory change command → Answer: C (cd)
+10. **Question 9**: chmod command purpose → Answer: A (Change file or directory permissions)
+11. **Question 10**: Mac terminal shortcut → Answer: B (⌘ + Spacebar, then type "terminal")
+
+## Notes
+
+This Java port maintains the same structure and answers as the original TypeScript quiz while leveraging the Java ecosystem and demonstrating cross-language compatibility.
