Write a GUI that generates a multiplication or division table. A multiplication or division table is a useful tool for learning simple multiplication and division sums.

The class ExpenseLedger will record all the expenses you make. You record an expense by giving it a serial number, a description (that tells what it is about) and the money you spent on this item. So you need to create a class ExpenseItem with serial, description and amount. Provide constructors, getters and setters. Also provide toString for this class. Now in the ExpenseLedger class you need to build a collection that will hold the instance of ExpenseItem. Provide the following methods in the ExpenseLedger

1.      void addExpense(description, amount): You should be able to figure out the serial of the expense yourself. This method will create an expense item and add it to the ledger. 

In UG Boys Hostel Having 5 floors and each floor having 15 rooms. Consider you have to allocate the hostel room for students of IT department using hashing techniques (Hint: Key=201IT253).

Write a Java program that creates an Account object with an account ID of 1122, a balance of $20,000, and an annual interest rate of 4.5%. Use the withdraw method to withdraw $2,500, use the deposit method to deposit $3,000, and print the balance, the monthly interest, and the date when this account was created.

Demonstration and Viva will be carried out in week 13 during your respective seminar session.

You will be assessed on the working of the code as well as on your ability to explain the code.

Design a class named Account that contains:

 A private int data field named id for the account (default 0).

 A private double data field named balance for the account (default 0).

 A private double data field named annualInterestRate that stores the current

interest rate (default 0). Assume all accounts have the same interest rate.

 A private Date data field named dateCreated that stores the date when the account was created.

 A no-arg constructor that creates a default account.

 A constructor that creates an account with the specified id and initial balance.

 The accessor and mutator methods for id, balance, and annualInterestRate.

 The accessor method for dateCreated.

 A method named getMonthlyInterestRate() that returns the monthly interest rate.

 A method named withdraw that withdraws a specified amount from the account.

 A method named deposit that deposits a specified amount to the account.

 Draw the UML diagram for the class.

 Implement the class.
