Java

You have several JRadioButtons on your GUI to allow the user to select the color of the item they are ordering. Unfortunately, the program currently allows the user to select more than one JRadioButton at a time. What do you need to do in order to get the normal (only one selected a time) behavior?

Question 11 options:

	use JCheckBoxes instead of JRadioButtons
	set the selection mode of the JRadioButtons to SINGLE_SELECTION
	write code to manually deselect the other radio buttons when a new one is selected
	add the JRadioButtons to a ButtonGroup
