CS 142 Lab 1

Welcome to lab!

Welcome to the lab section of COMP 142-today, we’ll be focusing primarily on a group programming assignment (detailed below!). Go ahead and pair up with a partner and begin working. (If you can’t find a partner, let me know, and I can help you pair up.) This webpage should give you a good breakdown of what to expect from this lab. Remember that both partners need to submit all assignment files and that everything is due by tonight at midnight!

I know you have experience with our half-lab half-lecture class from last week, but this is the first time you’ll be doing graded work as part of your lab! Throughout this lab and this class, please let me know if you have any questions!

Wheel of Fortune

  • Start IntelliJ. In the top-left corner of the screen, click the project dropdown and choose “Get from VCS.” This is the same approach we used earlier for in-class work. We will make a new project to store all of our labs and code that I want to distribute to the whole class. (This will copy my code from online into a new project-I recommend you put this in a directory with the other COMP 142 projects. Intellij should automatically set this to the directory you’ve used most recently.)

  • On the next screen, copy and paste in the following URL in the box that says “URL”:

    https://github.com/ncp38/cs142-s24-inclass

  • In the “Directory” box, double-check that the folder listed is the right place for new projects to be stored (a subfolder of your main cs142 projects). If something is off, you can click the folder icon at the far right of the text area and make a new folder for this class work.

  • In the left-hand panel, expand the src folder to see today’s lab (in the lab1 folder). Double-click on WheelOfFortune (not the md file yet.) If you get a message at the top that says “Project JDK is not defined,” then click on “Setup SDK” and choose the JDK you downloaded earlier.

  • In the left-hand panel, double-click on WheelOfFortune.md. Follow the instructions in this file. This is where you will answer the questions for the lab.

Submitting the lab

At the end of the lab session, upload the two files to canvas. Important! Make sure both you and your partner submit the .java file and the question file. You can find these files by hovering over the file name in the top bar in IntelliJ and right-clicking (or ctrl+click for Macs) and selecting Open in -> Explorer (for Macs, you’ll instead want to select Open in -> Finder).

-Each Java file you upload should include a header with an assignment title, your name, class number/period, and your teammates’ names. (Your names need to be listed in the questions.md file as well!)

-Beneath this header include a short description of what you’ve changed in the file.

For example:

//Lab 1 - Wheel of Fortune
//John Doe, COMP 142 Section 1
//Jane Deere, COMP 142 Section 1
//Changed lines 250-265 to allow the user to bet their earned money on a letter.
