# Summary

Throughout this jam, you've built a strong foundation in several key Java programming concepts:

1. **Build System Mastery**
- Configured Gradle for professional Java development
- Learned about build automation and dependency management
- Gained experience with industry-standard project structure

2. **Control Flow & Decision Making**
- Implemented switch statements for clean branching logic
- Handled user input validation effectively
- Created robust error handling mechanisms

3. **Array Operations**
- Mastered Java array syntax and operations
- Implemented both iterative and recursive solutions
- Developed efficient array manipulation algorithms

4. **Statistical Analysis**
- Applied programming to real-world data analysis
- Implemented statistical measures like mean and median
- Used enums for type-safe constant management

## Looking Ahead

In the next jam, we'll build on these foundations as we explore:

- Object-oriented programming concepts
- Class design and implementation
- Unit testing with JUnit
- More advanced data structures

# Project Structure

The following new files should be in your repository:

csci205_jams/
├── src/
│   └── main/
│       └── java/
│           ├── jam04/
│           │   ├── Calculator.java
│           │   ├── ArrayChallenge.java
│           │   └── Skewness.java
│           └── module-info.java
├── .gitattributes
├── build.gradle
├── gradlew
├── gradlew.bat
└── settings.gradle

# Submission

Before submitting your work, complete this final checklist:

1. **Code Completeness**
- All required files are present and in correct locations:
- `Calculator.java` with working operations
- `ArrayChallenge.java` with all methods implemented
- `Skewness.java` with statistical analysis
- All Gradle configuration files
- All files compile without errors
- All programs run correctly

2. **Documentation & Style**
- Code includes proper JavaDoc comments
- All methods are properly documented
- All Java files pass checkstyle verification
- No style warnings remain in any file

3. **Testing**
- All test cases pass
- Calculator handles all operations correctly
- Array methods work with various inputs
- Skewness analysis produces correct results

4. **Version Control**
First, push your feature branch as a backup:

   # Ensure all changes are committed
   git status
   
   # Push your jam04 branch to remote
   git push origin jam04

Then, merge your work into main:

   # Switch to main branch
   git checkout main
   
   # Merge your jam04 branch into main
   git merge jam04
   
   # Push main to remote
   git push

🚨 **Important Submission Notes**

1. Branch Management:
- Main branch should contain your final, working submission. This is what we grade.
- Keep your `jam04` branch until grading is complete. This serves as a backup of your work.

2. Code Quality:
- Verify your code is in the correct package (`jam04`)
- Double-check all file locations match the project structure
- Run checkstyle verification on all Java files

3. Repository Status:
- Both `jam04` and `main` branches should be pushed to GitLab
- Working directory should be clean
- All changes should be committed
- The instructors can only grade what's in your GitLab repository

🚧 **Important**
Always verify your work appears on [gitlab.bucknell.edu](https://gitlab.bucknell.edu/). The instructors and graders can only see and grade what you've properly pushed to your remote repository.
