Repetition, files, and Colors

Learning Objective(s)

  1. Reinforce repetition
  2. Learn to use for statement
  3. Learn to read from a file

Overview of the Program

The program is to allow the user to guess colors in a file. The file contains numbers representing colors with 4 per row. The program is to allow the user to guess each color and output the number correct.

Details

  1. Your colors are to be read, blue, green, and yellow.
  2. You must use constants for the colors and the number of colors per line in the file.
  3. Reject any invalid numbers (out of range)
  4. Use a for loop to the colors in one row
  5. Program should be called CheckColors

Example program dialogue:

These are not meant to be sufficient testing. Nor must you follow the exact wording. They are just to demonstrate what an acceptable program might do for certain input
An example of the data file is:
1 1 1 1
2 2 2 1
1 2 3 4
An example of an acceptable dialogue:
What is the name of file? datafile

Submission

  1. create an empty zip folder
  2. place your java file into it
  3. create a pdf document that contains your Software Development Report for this program and place the pdf file into the zip folder
  4. submit the zip folder on canvas

Hints

  1. Program design
  2. I feel overwhelmed. How should I start?
  3. Hint for file problems
  4. Once the user gets 4 colors right, the row is always guessed correctly
  5. I get too many lines of output

Optional improvements

Optional improvements should ONLY be worked on once the program is completing working. In addition, the work is to be done on your own with little if any help for lab assistants or the instructor.
  1. Allow the user to input the colors as a string and the code not be case sensitive.
