How to ensure that the hashset of Solutions behaves correctly?I'm failing the 2nd last requirement, but I am not sure why. The task description says that the main method isn't tested, so I don't know how to go about passing this test. I'm getting the correct answer as far as I can tell. I'm just spinning in circles trying to solve this.

Just clarifying: The purpose of the method is to add up EACH new apple_object price, and not to display the price of the last apple_object. It wasn't difficult for me to reference the Class's variable, and to assign it the variable passed as argument. My difficulty was to understand what it was asked of me to do with it from the description statement. I mistakenly thought it was to print the last known price, not to accumulate all the p
