Question

Identify the false statement.

a. You can create an input dialog box using the showInputDialog() method; the method returns a String that represents a user's response.
b. You can use methods from the Java classes Integer and Double when you want to convert a dialog box's returned values to numbers.
c. A confirm dialog box can be created using the showConfirmDialog() method in the JOptionPane class; a confirm dialog box displays the options Accept, Reject, and Escape.

Answer 1

The false statement is option 'c', which inaccurately describes the options of a confirm dialog box. The correct options are Yes, No, and Cancel, not Accept, Reject, and Escape.

Step-by-step explanation:

To identify the false statement among the options provided, let's examine each one:

• a. You can create an input dialog box using the showInputDialog() method; the method returns a String that represents a user's response. This statement is true. In Java, the JOptionPane.showInputDialog() method is used to create a simple dialog box for user input. The user's input is returned as a String value.
• b. You can use methods from the Java classes Integer and Double when you want to convert a dialog box's returned values to numbers. This statement is also true. You can use the Integer.parseInt() method to convert the input String to an int, and the Double.parseDouble() method to convert it to a double.
• c. A confirm dialog box can be created using the showConfirmDialog() method in the JOptionPane class; a confirm dialog box displays the options Accept, Reject, and Escape. This statement is false. The correct options provided by a confirm dialog using JOptionPane.showConfirmDialog() are Yes, No, and Cancel, not Accept, Reject, and Escape.

Therefore, the false statement is option 'c'.
