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”.

Travel Tickets Company sells tickets for airlines, tours, and other travel-related services. Because ticket agents frequently mistype long ticket numbers, Travel Tickets has asked you to write an application that indicates invalid ticket number entries. The class prompts a ticket agent to enter a six-digit ticket number. Ticket numbers are designed so that if you drop the last digit of the number, then divide the number by 7, the remainder of the division will be identical to the last dropped digit.
Accept the ticket number from the agent and verify whether it is a valid number.
Test the application with the following ticket numbers:
. 123454; the comparison should evaluate to true
. 147103; the comparison should evaluate to true
. 154123; the comparison should evaluate to false
Save the program as TicketNumber.java.
In the class String, the substring method inserts a String into another String.
-True
or
-False

1. Write an application that throws and catches an ArithmeticException when you attempt to take the
square root of a negative value. Prompt the user for an input value and try the Math.sqrt() method on
it. The application either displays the square root or catches the thrown Exception and displays an
appropriate message.
2. Create a program that allows a user to input customer records (ID number, first name, last name,

- handler: This method retrieves whatever the user has typed into the upper entry, converts it into an integer, calls the method getAge() to determine the equivalent cat age for the specified number of years, and places the cats's age into the lower entry. If the user enters something into the upper entry that cannot be evaluated as an integer or can be evaluated as an integer and is negative (e.g., less than zero), the handler displays a showinfo box with an appropriate message (title="Ooops!", message="The number of years is invalid.") and then clear() upper entry and lower entry instead of duplicating the code.

- switch_player(): we will allow the players to choose their own names, but for our purposes, it is easier to think of them as number (0 and 1, for indexing purposes). We will display their names to them on the screen, but in the background, we will keep track of them based on their number. This function should take 1 argument, an integer (either 0 or 1) representing the player and should return the opposite integer (1 if 0 is entered and 0 if 1 is entered). This is a simple function, but it will make our code cleaner later. Use your constants!
