Question

Okay, can someone please tell me what I am doing wrong??

I will show the code I submitted for the assignment. However, according to my instructor I did it incorrectly but I am not understanding why. I will show the instructor's comment after providing my original code for the assignment. Thank you in advance.

* * * * * What needs corrected based on the following comment by instructor * * * * *

For this assignment, you were supposed to create a constructor that that accepts those instance variables and performs some input validation and then prints an error message. Then, the HourlyTest class checks the weeklyPaycheck amount and, if it's 0, prompts the user for input again.

Please help!
