Things to bring to the exam

MUST BRING

• A laptop with Java, BlueJ, and with the password-protected exam downloaded. I will post the URL of the exam the day before the exam. You will get the password when the exam starts
• During the exam, you will see a file, index.html, in the unzipped folder. Open that. But remember that Codecheck does not work with Safari.
• A USB memory stick. If you want it back, put a label with your name on the outside. This is back-up in case there is an Internet problem
• A charger and perhaps an extension cord if your battery will not last for the entire exam.

MAY BRING

• Your textbook downloaded on your laptop
• The Java API installed on your machine (if you want to use it)
• Any Java code - on your laptop
• Notes
• A piece of papaer

MAY NOT

• Connect to the Internet during the exam except for Canvas and Codecheck

WARNINGS

• I recommend that on your Windows system that you disable automatic updates before the exam (or set a metered connection). More than once, Windows has decided it was time to update a student's computer at the beginning of the exam. It can take 30 minutes to update and restart.
• Sometimes when you download the browser thinks the file is suspicious and has a Discard button. Click the arrow next to the button and select "Keep"

Rules for the exam

• I may be able to give you partial credit even if your code fails Codecheck. To be elligible for partial credit, the code must compile.
• You should download the exam file the day before the exam.
• The day of the exam, I will give you the password to upzip the file. (Windows users, be sure to acutally unzip the folder)
• Code in Bluej to reduce the server load.
• The first couple of problems do not have a starter file, so you will not need to access Codecheck until your code is working in Bluej.
• The instructions are in the html file in the exam folder. Double click to open the exam. If Safari is your default browser, right click on index.html and select "Open with" Google Chrome
• You may not connect to any Internet site except Codecheck and Canvas. You may not access any communication software - Facebook, Twitter, email, instant message, etc.
• The exam period ends at 2:25. You have 5 minutes to finish uploading. Use that 5 minutes to upload the files to Canvas. Do not keep coding. Do not use Codecheck. The exam will close at 2:30. If you do not upload your files, you must talk to me promptly after the exam.
• You may not submit anything after the exam is over and you leave the room.
• You may not leave the room until the exam is over.
• The instructions are in the html file in the exam folder. Double click to open the exam
• You may use your textbook and material on your computer
• You may NOT communicate with anyone during the exam.
• You may NOT use the work of anyone else without attribution. This means if you have copied code from an Internet site like stackoverload.com, you must put the URL of the page with the code in a comment in your file.
• You may NOT use any web sites except Canvas and Codecheck
• When you are finished, upload signed.zip files you created, all at the same time,
• If you can not upload to Canvas, put your signed.zip files on your USB and turn that in. Put your files in a folder named lastName_firstName. If you want the USB back, put your name on the drive itself.

• You must stay in the room until the end of the final period. If you anticipate finishing early, bring something to do. You may not surf the net nor use your cell phone.
• You may not leave to go the the bathroom or for any other reason. Go to the bathroom before the exam and tell your friends you will return cell phone calls and text messages after the exam.
• If your battery does not last the entire class, be sure to bring a power strip
• If you are able to upload, do not worry if your submission is marked late. No points will be deducted.
• As you finish each problem, submit to Codecheck and download the report.
• Upload all the report files at once.

• You will upload 7 signed.zip files. signed.zip files files are what you download from Codecheck.
• If you have to give me a USB, put the files in a folder named yourLastName_yourFirstName

Warning message

For some reason, Chrome sometimes give you this warning when you download the report from Codecheck.

  • use nextLine() to read a multi-word line
  • Use hasNextInt or hasNextDouble to avoid exceptions
• Use an if statement to determine which alternative to execute
  • To determine is a number is positive negative or zero, you should use if / else if / else and not if / if / if
• Use nested ifs
  • example on page 201 in textbook
• Be able to write a class
  • instance variables
  • constructors
  • methods
  • Examples in Chapter 3 and Udacity videos

  • substring,
  • contains,
  • replace.

• Implement an interface, especially the Comparable interface
  • Example: hw11
  • Example: page 477 in the textbook
  • Udacity videos
• Create a subclass
