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. Page 10 of 8 • 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. 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.
OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
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. 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.
