Please navigate to the course Gradescope and complete the quiz “HW 0 Checkpoint, Collaboration, and Style Questions” to ensure that you fully understand our course policies. You will be able to see your results immediately and retake the quiz as many times as necessary. For aid in completing the quiz, you should use the tabs under the “Policies” dropdown on the course website, as well as our Style Guide.


Hello World


1. Getting Started


Goals

The purpose of this assignment is to introduce you to coding in Java and familiarize you with the mechanics of preparing and submitting assignments. The specific goals are to:


Preface

If you find yourself needing help with this or any other assignment, please refer to our getting help page for the resources we have available.


Ed Discussion

The class discussion board is hosted on Ed. You should be automatically enrolled in the Ed course. Please contact one of the Head TAs if you are not.

Use Ed to:


Software Setup

We will be using Codio this semester - enroll in the Codio course by clicking the link at the course website.


2. Hello, World!

Program Overview and Setup

This part of the homework walks you through completing your first program! Traditionally, the first program anyone writes in a new language just prints, “Hello, World!” to the interactions pane.


3. Example Drawing

The cis110 jar file sets up tools to help you draw graphics and play sound (StdDraw and StdAudio) that are very simple to use. For CIS 1100, however, we will be using a drawing library that we have called PennDraw. Before you make your own drawing, you will study our example drawing of a house to understand how the PennDraw library works.

To do this part of your HW:

  1. Click Compile in the Codio dropdown.
  2. Click Run MyHouse in the Codio dropdown.
  3. Click View Running Program next to Run MyHouse.
  4. You should see a drawing appear in a new window. If so, close the window and continue with the assignment. If not, we’ll be happy to help you.

We have provided you with example code in MyHouse.java to make sure that drawing is working on your computer. It also gives you some examples of what can be drawn using the PennDraw library. Read the PennDraw documentation to see what you can draw (i.e. shapes, images, text…) using PennDraw. The documentation page lists all of the functions you can use and explains how to use them.

Open the file MyHouse.java in Codio. Ensure that the provided code compiles and runs on your computer. Pay attention to the comments in the code (the text that begins with “//” which appears in green) as they will help you understand what each line of code contributes to the drawing you see.


4. Your Own Drawing

You will now write your own program which will create a drawing (like the one you saw in MyHouse.java).

My Sketch Specifications

Find the file MySketch.java in Codio. Use your HelloWorld and MyHouse programs to guide you in writing this new program. Design and create your own piece of digital art using Java and the PennDraw library. Think of yourself as a creative designer when choosing the topic of your design.

This is your very first program, so here are some guidelines:

Here are some ideas to get you started:


Readme

Every assignment will have an accompanying readme file that you will fill out and submit. This is a required part of the assignment and it usually takes only a few minutes. Among other things, the readme is where you can give any comments or feedback you have on the homework.


HW0 Gradescope Quiz: Checkpoint, Collaboration, and Style Questions

For this homework, please submit the HW0 quiz on Gradescope in addition to the HW0 assignment.


Submission

All homework will be submitted to Gradescope. You should be already enrolled in Gradescope through Canvas. If you don’t know your login details, go to the Canvas course and click on Gradescope. This should prompt you to create an account linked to your Penn email and you’re all set up to submit. Complete the following steps to submit your HW0 assignment:
