help me with a practice test question ? there is no answer

[stephanie904]

Which of the following statements is false ?

a) you must create an object of class JOptionPane to use its static method showMessageDialog.

b) JOptionPane method showInputdialog displays an input dialog containing a prompt and a field (known as a text field) in which a user can enter text.

c) String method format works like method System.out.printf, except that format returns the formatted String rather than dislpaying it in a command window.

D) An input dialog allows the user to enter data into a program.

Why don't you write a few lines of code to test that?
