Hello.
Excuse my poor English.
I have a stupid program that has a three JRadioButton named R, G, and B.
When it is launched, no button is selected. Window is made of one JPanel.
First time, the JPanel's background color is default.
Next, when R button is selected, the background color of the JPanel turns into
red, when G is selected the color turns into green, and when Y, Yellow.
For such a program, normal requirements are that one JRadioButton is selected
when it is launched and that there is at least one another feedback of button
selection (e.g. background color).
My stupid program does not meet these requirement. But if there is a way to
emulate JRadioButton's clicking from code, I can meet them.
Is there such a way?
Am I thinking in a wrong way?
Thank you in advance.

See AbstractButton.setSelected() or AbstractButton.doClick() in the
javadoc. (Note that JRadioButton extends AbstractButton.)
