It is possible to deposit and withdraw funds, to add interest, and to find out the current balance.

A method deposit it for depositing a specified amount. A method withdraw for withdrawing a specified amount. A method addInterest for adding interest to the account. The addInterest method takes the interest rate as a parameter and changes the balance in the account to balanced* 1+rate). The UML diagram for the Account class is shown in the following UML diagram.
