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 currentinterest rate (default 0). Assume that all accounts have the same interest rate.■■ A private Date data field named dateCreated that stores the date when theaccount 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 monthlyinterest rate.■■ A method named getMonthlyInterest() that returns the monthly interest.■■ A method named withdraw that withdraws a specified amount from theaccount.■■ A method named deposit that deposits a specified amount to the account.Draw the UML diagram for the class then implement the class. (Hint: The methodgetMonthlyInterest() is to return monthly interest, not the interest rate.Monthly interest is balance * monthlyInterestRate. monthlyInterestRateis annualInterestRate / 12. Note annualInterestRate is a percentage,for example 4.5%. You need to divide it by 100.)Write a test program that creates an Account object with an account ID of 1122, abalance of $20,000, and an annual interest rate of 4.5%. Use the withdraw methodto 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.

Draw the UML diagram for the class then implement the class. (Hint: The method
getMonthlyInterest() is to return monthly interest, not the interest rate.
Monthly interest is balance * monthlyInterestRate. monthlyInterestRate
is annualInterestRate / 12. Note annualInterestRate is a percentage,
for example 4.5%. You need to divide it by 100.)
Write a test 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.
