Welcome to AP Computer Science A. If you are a student in the class, the first thing you need to do (and which we should have done in class) is set up your GitHub account.
Once you have a GitHub account, click “Log in to GitHub” below to proceed.
If you don’t have a GitHub account yet, please create one and then log in here for further instructions.
Congratulations! You have successfully connected this app to GitHub. However you are not yet a member of the GitHub organization for this class, something Mr. Seibel needs to set up for you.
This is your GitHub profile URL:
Click the clipboard icon to copy it and then submit it at this form so he can add you.
Congratulations! You have successfully connected this app to GitHub. And it looks like you have an invitation to join the GitHub organization for this class. You need to accept that invitation before you can proceed. The invite should be sent to whatever email you used when you created your GitHub account.
I see you are logged into GitHub and a member of the berkeley-high-cs GitHub organization. However there seems to have been some problem finishing the setup for your account. Please let Mr. Seibel know.
This is a tool for the AP Computer Science A class at Berkeley High School. It is intended to provide a simple environment for experimenting with Javascript without all the complexities of a full development environment such as ReplIt or Glitch which we may use later in the year.
It is also designed to take advantage of the browser’s ability to run Javascript natively. It does not need access to a server to run code making in extremely responsive even if the Wifi is flaking out.
Finally, under the covers it is saving work to a GitHub repository in a very simplified workflow that does not depend on immediately learning any git commands. Code written in this environment for each assignment is saved to a directory and branch specific to that assignment each time it is saved. Thus when the assignment is done, it is easy to go to GitHub and create a PR containing just the work on that assignment which can then be commented on and worked on further before it is turned in and merged to main.
You're all set! You don't need to worry about this yet but we have successfully created a GitHub repository for your work:
You can get to it any time by clicking on your GitHub username at the top-right of the screen.
Write a class Circle that extends the class
Shape (not shown) . Shape has a single
constructor that takes a String specifying the color of
the shape. Note, do not make it public because are
going to be two classes and there can’t be multiple
public classes in one file.
Your Circle class should have a single constructor that
takes two arguments: a String specifying the color and
a double specifying the circle’s radius. You also
implement a method area that takes no arguments and
returns the area of the circle. (In case you forgot the area of a
circle is Math.PI times the the square of the radius.)
Write a class Rectangle that extends the same class
Shape class as in the previous problem. Also as before,
do not make it public because are going to be two
classes and there can’t be multiple public classes in
one file.
Your Rectangle class should have a single constructor
that takes three arguments: a String specifying the
color and two doubles specifying the rectangle’s width
and height. You should also implement a method
area that takes no arguments and returns the area of
the rectangle. (In case you forgot the area of a rectangle is its
width times its height.)
