Trouble with a problem in Java called FirstnameLastname I replaced Firstname wit

Question

Trouble with a problem in Java called FirstnameLastname I replaced Firstname with my first name and Lastname with my last name). Now I just need to figure out an ArrayList called BookList. It should display a menu to allow the user to choose from the following options:

Enter 1 to add a book
Enter 2 to edit a book
Enter 3 to remove a book from the list: Enter 4 to display the list of books: Enter 5 to quit:

The program should use a case/switch statement and switch on the users choice. The program should continue until the user enters 5 to quit. Case 1 should use BookList.add to add books to the ArrayList. Case 2 should use BookList.set to edit books to the ArrayList. Case 3 should use BookList.remove to remove a name from the list (Ask the user to enter the index number of the book to delete from ArrayList). Case 4 should use a for loop to display all books in the ArrayList along with their index number. Any help would be appreciated . display should be a menu list output of what the user types in . Thanks Jason :)

Explanation / Answer

BookList.java

import java.util.ArrayList;
import java.util.List;
import java.util.Scanner;

public class BookList {

   /**
   * @param args
   */
   public static void main(String[] args) {
       // TODO Auto-generated method stub
       java.util.Scanner in = new java.util.Scanner(System.in);
       List list = new ArrayList();
       while(true){
           System.out.println("Choose your Option: 1) Add a Book 2) Edit a Book 3) Remove a Book 4) Display the list of Books 5) Quit");
           int choice = in.nextInt();
           switch(choice){
           case 1: addBook(list, in); break;
           case 2: editBook(list, in); break;
           case 3: removeBook(list, in); break;
           case 4: displayBooks(list, in); break;
           case 5: System.exit(0); break;
           }
       }
   }
   public static void addBook(List list, Scanner in){
       System.out.println("Please enter book name");
       String name = in.next();
       list.add(name);
       System.out.println("Given book added ");
   }
   public static void editBook(List list, Scanner in){
       System.out.println("Please enter book name");
       String name = in.next();
       System.out.println("Please enter the index where this book to be inserted");
       int n = in.nextInt();
       if(n > list.size()-1){
           System.out.println("Given index is too high. The size f book list is "+list.size());
       }
       else{
       list.set(n, name);
       }
       System.out.println("Given book updated with the index");
       }
   public static void removeBook(List list, Scanner in){
       if(list!=null && list.size() > 0){
       System.out.println("Please enter book name");
       String name = in.next();
       list.remove(name);
       System.out.println("Given Book removed from the list");
       }
       else{
           System.out.println("No books Avalable");
       }

   }
   public static void displayBooks(List list, Scanner in){
       System.out.println("-------------List of Books Display-----------------");
       for(int i=0; i<list.size(); i++){
           System.out.println(list.get(i));
       }
   }  

}
