+# 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.

+#
+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/HEAD/platforms/jvm/plugins-application/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+#       within the Gradle project.
