Hello. I've hit a brick wall on an assignment for class. I've included the instructions and what I have gotten so far. My major problem is converting the number for days of the week to the actual day. Any help will be greatly appreciated. Thanks!
Insert code into the Clock class to enable it to perform the necessary functions. You may add as many additional methods and/or attributes you deem necessary. The driver class ClockDriver is already provided - test the performance (and output) of the Clock class using the ClockDriver class.
The following is a sample output based on the numeric values used in main() in the attached sample ClockDriver class. Please check your program's output by using different numeric values in main():
run:
Thursday, 12:00 pm
Thursday, 2:30 pm
Friday, 12:15 am
Friday, 12:15 am
Thursday, 2:30 pm
Saturday, 2:30 pm
BUILD SUCCESSFUL (total time: 0 seconds)
