Java Composite Shapes GUI

A small Java Swing application that lets you create and manage composite shapes in a graphical interface. Use it to experiment with grouping shapes, moving them together, and visualising how composite objects behave.

What is this project?

This project is a CS230 assignment focusing on Java and OOP. It demonstrates the Composite design pattern using a simple GUI. It provides a canvas and controls to add basic shapes, combine them into composites, and manipulate them as a single unit.

How to use

1. Build the project

   javac -d bin src/*.java

2. Run the app

   java -cp bin Main

3. In the GUI
   • Add shapes using the provided controls.
   • Select multiple shapes and group them into a composite.
   • Move or edit composites to see grouped behavior.

Notes

• If your entry point class is different from Main, update the run command accordingly.
• The project is intentionally minimal to keep the focus on the composite behavior.
