[Solved] How to delete item from array list Java eclipse

Question

I advise you re write your code. One mistake to note, you are attempting to create objects of type List. List is not a class and cannot be instantiated, it is an interface that contains methods to be implemented but these methods contain no bodies. To use java.util.List, you must implement it and then implement the methods in the interface providing the bodies for them. If you need a list of some sort, you need to use an java.util.ArrayList or java.util.LinkedList depending upon your needs.

Other than that, the code you have posted on here is too long, youre best to find which block of code the error is in, and tell us what exceptions or error messages you get.
