Chapter 6, Problem 2PC
Car Class
Write a class named Car that has the following fields:
- yearModel. The yearModel field is an int that holds the car’s year model.
- make. The make field references a String object that holds the make of the car.
- speed. The speed field is an int that holds the car’s current speed.
In addition, the class should have the following constructor and other methods.
- Constructor. The constructor should accept the car’s year model and make as arguments. These values should be assigned to the object’s yearModel and make fields. The constructor should also assign 0 to the speed field.
- Accessors. Appropriate accessor methods should get the values stored in an object’s yearModel, make, and speed fields.
- accelerate. The accelerate method should add 5 to the speed field each time it is called.
- brake. The brake method should subtract 5 from the speed field each time it is called.

Question 1:
E-Hailing Bicycle Management System
Case Study:An e-hailing company that rents out bicycles needs a system to manage its bicycles, users, and borrowing process. Each user can borrow up to 2 bicycles at a time, specifically for families with children 18 years or below. The system must track the bicycles (name, make, type, and availability) and users (name, ID, and borrowed bicycles).
The company also wants to ensure that the system uses a multidimensional array to store information about the bicycles.
Requirements:
Add and View Bicycles:
Borrow Bicycles:
Return Bicycles
Display Borrowed Bicycles and Search for a bicycle
Create a menu-driven program to implement the above.
Sample Output:
Add Bicycle
View All Bicycles
Borrow Bicycle
Return...
Add a method called transfer () to the BankAccount class, that takes in an amount and
destinationAccount as input and transfer the funds from current account to destination
account.
This method should return the balance of the current account after the transfer, also should
check for the sufficient balance in current account before proceeding the transfer and if there is
insufficient balance return an error message "Insufficient balance".
Modify the BankAccount Test class, so that it calls the transfer () method and prints the
balance after transfer.
Make sure that the transfer() method updates the balance of both the current account
and the destination account.
• Create a public method called deposit() that takes in an amount of type double as input
and adds the amount to the current balance. This method should also return the updated
balance.
• Create another public method called withdraw() that takes in an amount of type double as
input, checks if the withdrawal amount is less than the current balance, and if so, subtracts
the amount from the balance. If the withdrawal amount is greater than the current balance,
the method should return an error message "Insufficient balance".
• Create a public method getAccountInfo() that returns the account information in the format
"Account Number: xxxxx, Account Holder: John Doe, Account Type: SAVINGS/CHECKING,
Balance: $xxxX.XX".
• Finally, create a constructor method that takes in the account number, account holder name,
initial balance and account type as input and initializes the corresponding instance variables.
In the BankAccount class, make sure to use the private access modifier for the
instance...

- Create a BankAccount Test class that contains a main() method that instantiates an object of type BankAccount, with account number of 12345, account holder name of "John Doe", initial balance of 1000ドル and account type as SAVINGS . Then use the deposit() and withdraw() methods of the object to deposit 500ドル and withdraw 300ドル. Finally, use the getAccountInfo() method to print the current account information. Use the getAccountInfo() method to verify that the deposit and withdrawal actions are performed correctly and that the account information is updated accordingly.arrow_forwardAdd a new class checkingAccount that inherits from the BankAccount class, and has a double instance variable overdraft Limit in addition to the variables inherited from the superclass. • Create a constructor for the checking Account class that takes in the account number, account holder name, initial balance, account type and overdraft limit as input, and uses the super keyword to call the constructor of the superclass, passing in the account number, account holder name and initial balance, account type. • Re-write the withdraw() method in the checkingAccount class so that it first checks if the withdrawal amount is less than the current balance plus the overdraft limit. If it is, the withdrawal is allowed and the balance is updated.
