Q2. Write a program that creates a class named BankAccount and contains: • Private attributes: • • ° ° id int), balance double and annual InterestRate (double). These attributes must never take a negative value. beneficiaries String [] ) to store the names of people who may receive the balance of funds when the account owner passes away. count static int ) to keep a record of the number of created objects. Constructors: 。 A 3-argument constructor that creates an account with given annual InterestRate), balance, and list of beneficiaries passed to the constructor as a series of names, e.g. BankAccount(3300, 6.7, "John", "Lili"). The constructor must increment count by 1, and then stores the new count into id. 。 A no-argument constructor that invokes the above 3-arg constructor and sets both balance and annual Interest Rate to 0, and beneficiaries to a new empty (String array of the size 3. Methods: ° Getter methods for all attributes. ° Setter methods for balance, annual Interest Rate ° ° ° ° Setter method for beneficiaries using the header: public void setBeneficiaries(String list) getMonthly Interest() : returns the monthly interest (not the interest rate). Monthly interest is calculated as balance * annualInterestRate / 12. Note: the interest rate is a percentage, e.g. 4.5%. You need to divide it by 100. getNumberOfBenefitieries (): returns the number of beneficiaries on this account. withdraw(double amount): withdraws a specified amount from the account. deposit (double amount): deposits a specified amount to the account. displayInfo(): displays the information of a bank account as shown in the sample run. Write a test program that creates an object of BankAccount with a balance of $33,000, and an annual interest rate of 6.7% with two beneficiaries named: John and Lili. Use withdraw to withdraw $1,500, use deposit to deposit $1,000, then use displayInfo to display the account information. Sample run: Account ID: 1 Current balance: $32500.0 Annual interest rate: 6.700 % Monthly interest rate: 0.558 % Monthly interest: $181.458 2 beneficiaries: [John, Lily]
