Modify the library program as follows:
Create a method in the LibraryMaterial class that accepts a
string s as a parameter and returns true if the title of the string
is equal to s.
Create the same method for your library material copies. Note that
it will need to be abstract in the LibraryMaterialCopy class

FOR JAVA: Summary: Create a program that adds students to the class list (see below). The solution should be named Roster402_v2.java. Allow the user to control the number of students added to the roster. Ask if the user would like to see their new roster to confirm additions. If yes, then display contents of the file, if no, end the program. ------------------------------------------------------------------------------------- List of student names and IDs for class (this will be your separate text file): Jones, Jim,45 Hicks,...

this needs to be in Java:
use a comparator class which
is passed into the sort method that is available on the
ArrayList.
import java.util.Scanner;
public class Assign1{
public static
void main(String[] args){
Scanner reader = new Scanner (System.in);
MyDate todayDate = new MyDate();
int choice = 0;
Library library = new Library();
while (choice != 6){
displayMainMenu();
if (reader.hasNextInt()){
choice = reader.nextInt();
switch(choice){
case 1:
library.inputResource(reader, todayDate);
break;
case 2:
System.out.println(library.resourcesOverDue(todayDate));
break;
case 3:
System.out.println(library.toString());

case 4:
