Explanation / Answer

AccountDriver.java

// class
public class AccountDriver {
   public static void main(String[] args)
   {
       // create object of class Account
        Account myAccount = new Account(127892, 2000, 0.2);
      
       // call function
       myAccount.withdraw(2500);
       myAccount.deposit(3000);
      
       // display result
       System.out.println("The balance of the account is $" +myAccount.getBalance());
       System.out.println("The monthly interest rate is " +myAccount.getMonthlyInterestRate()+ "%");
       System.out.println("The account was created " +myAccount.getDateCreated());
   }

}

Account.java
import java.util.Date;

public class Account {
   // declare variables
   private int id;
   private double balance;
   private double annualInterestRate;
   Date dateCreated;
  
   // constructor
   public Account()
   {
       id = 0101;
       balance = 100;
       annualInterestRate = .15;
       dateCreated = new Date();
   }
  
   // con with parameter
   public Account(int id, double balance, double annualInterestRate)
   {
       this.id = id;
       this.balance = balance;
       this.annualInterestRate = annualInterestRate;
       dateCreated = new Date();
   }
  
   // getting id
   public double getId()
   {
       return id;
   }
  
   // getting balance
   public double getBalance()
   {
       return balance;
   }
  
   //get interest rate
   public double getAnnualInterestRate()
   {
       return annualInterestRate;
   }
  
   // set id
   public void setId(int id)
   {
       this.id = id;
   }
  
   // set balance
   public void setBalance(double balance)
   {
       this.balance = balance;
   }
   public void setAnnualInterestRate(double annualInterestRate)
   {
       this.annualInterestRate = annualInterestRate;
   }
  
   // created date
   public Date getDateCreated()
   {
       return new Date();
   }
  
   public double getMonthlyInterestRate()
   {
       return annualInterestRate/12;
   }
  
   public void withdraw(double balance)
   {
       this.balance -= balance;
   }
  
   public void deposit(double balance)
   {
       this.balance += balance;
   }
}

output

                                                                                                                   
The balance of the account is $2500.0
