Activity 4 - More Practice with IntelliJ: Implement the Circle class

For this activity you will be creating a new IntelliJ project starting with some existing source code.

Starting up

• Go to https://skiadas.github.io/SoftwareDevelopmentPracticumCourse/ and then Schedule/Notes -> Activities for Day 1.
• Go to Activity 4 and follow the source code link.
• Right-click on either source code link (zip format), then download the file by selecting Save as. Be sure to save the file in your CS321 directory.
• Unzip the file to create a directory called “basicGraphing-WritingCircleAssignment”.
• In IntelliJ, select File -> New -> Project from Existing Sources.
• Follow the Next buttons until you can choose a project name and location.
• Click Finish to accept the suggested project name and location.

Implement the Circle class.

• Take a look around at the source code you have been given.
  • Notice that there are two packages (shape and ui) and a Main class at the top-level of the src folder.
  • The shape package contains two classes: Circle and Point.
• Try running the code:
  • Open “Main.java” and click on the green triangle to the left of public static void main... to try running the code.
  • At this point, the build process should fail with lots of complaints about the Circle class, which still needs to be implemented.
• In “Circle.java”, add the implementation for the Circle class that we developed in Activity 3.
• Once you get Main built and running, try out the simple interactive interface for testing the Circle class.
