Question

this needs to be in Java:

use a comparator class which is passed into the sort method that is available on the ArrayList.

Problem Description In this assignment, you will modify a solution to Assignment 1 with two modifications. You may start with your solution or my posted solution for Assignment 1. You must also submit a test plan for the functionality created in this assignment. You must add to your test plan from assignment 1 to include testing the new functionality. 1. Friendly Input: You will modify your Scanner object to use a delimiter of "\n", this will allow for spaces in our input. 2. Efficiency: You will update the Library Resource Checkout data structure in two ways: oChange the resourcesBorrowed declaration in Library class to be an object of ArrayList. o Change the insert into the resourcesBorrowed data structure so that the Resource objects are in alphabetic order from smallest to largest (as in the dictionary) by title in the most efficient way possible. (So the following titles would be in this order: A Bridge Too Far, Mamma Mia, To Kill A Mockingbird, Underworld). Once the resourcesBorrowed structure is sorted, modify your other methods to also make them as efficient as possible. (Note Generic Collection methods yet we will learn to do the coding ourselves first) Add a menu selection to display a particular resource based on input from the user of its title. The resource title should match ignoring differences in upper/lower case letters between input value being searched and stored title value. do NOT use 3. Saving data: You will add two menu selections to your assignment: file to the Library resourcesBorrowed Array List. (i.e. read). This should add to any The first will read the contents of resources which are already in the ArrayList. And the second will save the current contents of the Library resourcesBorrowed ArrayList to a file (i.e. write) File format is one data item per piece of data, depending on what kind of resource the file is describing, various numbers of lines are required. Many types of resources can be included in the same file. Each resource will be in the following formats: O Magazine Book DVD d m title of resource title of resource title of resource name of borrower due date month due date day due date year overdue cost name of borrower due date month due date day due date year overdue cost author name of borrower due date month due date day due date year overdue cost dvd type month еа edition year 4. Search: You will add the ability to view a resource given the title.
