Mastering Java: The Ultimate Quiz for 'Thinking in Java'

A JTextArea allows you to display and edit text with multiple lines. It is specifically designed for displaying large amounts of text and allows the user to scroll through the text if it exceeds the visible area. Option A is incorrect because a JTextArea allows for text editing, not just displaying. Option C is incorrect because JTextAreas are not designed for displaying images; you would use a JLabel for that purpose. Option D is incorrect because JTextAreas are not used for creating interactive buttons; you would use a JButton for that purpose.
