What is the primary purpose of the method setDefaultCloseOperation() in a JFrame?

To close the application when a user performs a shutdown maneuver
To set the frame's layout
To determine the frame's size
To make the frame visible

The correct answer is: To close the application when a user performs a shutdown maneuver

The primary purpose of method setDefaultCloseOperation() in a JFrame is to specify how the application should behave when the user clicks on the 'close' button or performs a shutdown maneuver. It does not affect the layout, size, or visibility of the frame. While these options can be altered with other methods, they are not the primary purpose of setDefaultCloseOperation(). Therefore, options B, C, and D are incorrect.
