Interactive Calendar: a Greenfoot project

Interactive Calendar

Greenfoot project 9 · all projects · part of Intro to Java with Greenfoot · not graded, and not tracked as progress

Switch statements, drawing images, and buttons that respond.

Before you start: finish lesson 3.9. That is the last thing this project needs. Starting earlier is allowed and you will hit a method nobody has shown you yet.

Part 1. Put this window on one side of your screen and Greenfoot on the other, then build along with it.

Part 2. Put this window on one side of your screen and Greenfoot on the other, then build along with it.

Methods you will use

Every one of these appears in the build. The lesson number is where the course teaches it, so if a row looks unfamiliar you have not missed anything, you just have not got there yet.

Method Taught in What it does here
private int month 3.8 which month is showing
public Button(String label) 3.9 buttons built from a constructor
addObject(...) 3.7 lay the buttons out

Not covered by the course

This project uses these, and the lessons never get to them. That is not a gap in your knowledge. Copy them from the video, or ask.

Method Why it is here
switch (month) { case 1: ... } the course teaches else if chains in 2.5 and never covers switch. An else if chain does the same job.
Greenfoot.mouseClicked(this) buttons that respond to a click.
getImage().drawString(...) drawing the dates onto the image.
