3. Write a program that simulates a telephone that records missed incoming calls. For each missed call, store the time of the call, telephone number of origin, and name of the caller if the name is available. For unlisted numbers, set the name to “private caller”. Choose or extend the most appropriate collection class and provide the following features:

   • a. Numbers are recalled in the order they arrive.
   • b. After each number display, the user can select:
     • i. To delete the call.
     • ii. To display the call details (number, caller name, and time). Delete the number if the user specifies a number to delete.
   • Write a helper class to represent an incoming call with fields to hold the number, name of the caller, and time of the call. Write a tester class that stores several numbers, simulates the user pressing the missed-calls button, and finally prints the entire collection of stored calls.

4. Write a Java program using user-defined storage classes to create a book database and store it in a Collection List:

   • a. The book collection should include title, author, publisher, and price.
   • b. Write a method to sort the books in ascending order of price and store them in another list. Maintain the book details with respect to a unique book ID.
   • c. Prompt for an author name and list all the books with the same author name.

5. Write a Java program using user-defined storage classes to create a book database and store it in a Collection List:

   • a. The book collection should include title, author, publisher, and price.
   • b. Maintain the book details with respect to a unique book ID. Create a new list holding all the book details with a price greater than a user-specified price.
