Repetition Lab: Factoring: Fall 2026

Learning Objective(s)

• Learn about event controlled loops (and use a priming read)
• Statement coverage for testing
• Enhance overall programming skills

Overview of the Program

Specifics

• The program is to be called Factoring
• The prime factors should be displayed in increasing order
• A priming read must be used

Sample dialogue

What number do you wish to have factored? 120
The prime factorization of 120 is:
2 2 2 3 5 
What number do you wish to have factored? 13

The prime factorization of 13 is:
13 

Lab Hints

• Hint 1: a flowchart that you can use
• Hint 2: See class examples for priming reads
• Hint 3: When to quit
• Hint 4: When to update

Submission

• Create a software development report
  • For the system design, you may use my flowchart if it is the design of your program. Otherwise, you need to make your own.
  • For testing report,
    • make sure your tests ensure that each statement is executed at least one.
    • your expected output CANNOT be pasted from the dialogue of a running. Only the actual output may be pasted
    • It should contain two different inputs that are "errors"
  • For the improvement section, specify how many points were lost from the last lab that you should not lose points for on this lab because you corrected the problem
  • create a pdf document from your software development report
  • create an empty zip folder
  • place only Factoring.java and your pdf document into it
  • submit the zip folder on canvas

Optional improvements

1. Allow the user to type in 2 numbers and print out the prime factors that are shared by both
2. Call this program Factoring2 add it to the zip folder that contains the original solution.
3. Add a section to the software development report entitled Extra Credit and explain the logic of your improvement and 2 sets of testing data
