Can someone walk me through why the remove button isn't working properly? It's suppose to remove the users input from the list (so if they list was made from Lisa Simpson, Harry Potter, and Clary Fray and the user input Harry Potter the list would then become Lisa Simpson, Clary Fray) but it is only asking for the input (Please enter first name: and Please enter last name:) and not removing it. I'm using Java Netbeans

Output example:

First Name Last Name Priority

Kathryn Quirk 1

Tom S 2

Lisa Blackburn 3

and if I wanted to remove someone it should ask for there name (lets say Tom S)and output:

First Name Last Name Priority

Kathryn Quirk 1

Lisa Blackburn 2
