Numerical Method Mid Semester Test

Bouncing-ball-with-velocity-and-energy-lost

This repository is for my Numerical Method Mid Semester Test.

Repository Structure

Main.java - The main running application and create window
Painter.java - Add color to the window backgorund, get window location, add color for ball and get ball location
Listener.java - Create listener function such as mouseClicked, mouseReleased, mouseDragges etc
Dropthread.java - All the logic for ball to bounce with gravity, friction and energy lost as consideration
Time.java - Get ball, mouse moving time
Shapeutils.java - To calculate whether the mouse click is within the ball

Run program

1. Clone this repo

2. Open cmd and type

java Main.java

Further improve

• Offset problem (x: -14, y: -37)
• Gradient of the 3D ball
• Add ceiling so ball cant exceed top of the window when using mouseDragged function
• Deformed shape
