Program Description Answer
The method that is used to make the text field readable is “setEditable”.
Hence, correct answer is option “D”.
Expert Solution & Answer
Explanation of Solution
Read-only text field:
- The text that can be changed only with the application code is called as read-only text field.
- The read-only text field will not allow the user to edit its contents.
- The usage of the “JTextField” component is made in a different way such that the text field cannot be edited by the user, instead it can be modified using the code of the application and it is made through the method “setEditable”
Format of defining the “setEditable” method:
The general format for defining “setEditable” method is given below:
setEditable(boolean editable)
Example:
The usage of the method “setEditable” for the text field that is generated is given below:
//create a new text field
JTextField Total=new JTextField(10);
//set the text field read only
Total.setEditable(false);
Hence, the method that is used to make the text field readable is “setEditable”.

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…
