**Could someone please fix my code**

I'm having issues with actually parsing through the txt file. If you run the code and run the loadEvents() method, you will see that it can NOT parse the data correctely and I'm unsure if it is because of the way I have my txt file written or the code itself. Please fix and help. If you do change the loadEvents() method, I need it to be able to read a file that is in the form

name of event

day(s) start date end date start time end time

As seen here:

MW 12:00 13:15 1/25/23 5/20/23

M = monday

T = tuesday

W = wednesday

R = thrusday

F = Friday

A = Satruday

S = sunday

**There can be recurring events just FYI** Thats why its MW in the example

Thank you in advance
