Programming Exercises

Please complete the following Programming Exercises. All programs must be formatted for easy readability, and commented with both a description at the top of each file and ample in-code comments. (1)(Points – 50) Create a class named LibraryBook that contains fields to hold methods for setting and getting a LibraryBook’s title, author, and pageCount. Save the class as LibraryBook.java. Write an application that instantiates five LibraryBook objects and fills in values for the data fields, in non-sorted order. Then continuously prompt the user to enter which field the LibraryBooks should be sorted by – title, author, or pageCount. Perform the requested sort procedure and display the LibraryBook objects. Continuously prompt the user until they indicate they are done sorting. Save the class as LibraryBookSort.java. (2)(Points – 50) Create class SavingsAccount. Use a static variable annualInterestRate to store the annual interest rate for all account holders. Each object of the class contains a private instance variable savingsBalance indicating the amount the saver currently has on deposit. Provide method calculateMonthlyInterest to calculate the monthly interest by multiplying the savingsBalance by annualInterestRate divided by 12—this interest should be added to savings-Balance. Provide a static method modifyInterestRate that sets the annualInterestRate to a new value. Write a program to test class SavingsAccount. Instantiate two savingsAccount objects, saver1 and saver2, with balances of $2000.00 and $3000.00, respectively. Set annualInterestRate to 4%, then calculate the monthly interest for each of 12 months and print the new balances for both savers. Next, set the annualInterestRate to 5%, calculate the next month’s interest and print the new balances for both savers.
