Please someone please fix my code

I'm having issues with the [ private static void load() throws FileNotFoundException ] method. I can't get this method to properly parse through my txt file. I have asked people on chegg so many times but it never works so please copy this code and test it yourself before answering so that I can get the right answer.

This is my events.txt file that I'm using when running this code:

**AGAIN PLEASE RUN THE CODE YOURSELF BEFORE ANSWERING TO ENSURE CORRECTNESS**
