From CRPC Lectures on Java Language Applets Graphics CRPC Annual Meeting Tutorial -- May 14,1996. by Geoffrey C. Fox
Radiobuttons are identical to Checkbox's but grouped so that only one in a group can be on at a time. They use same class for buttons but add CheckboxGroup class
CheckboxGroup cbg = new CheckboxGroup(); // cbg is group for one set of radiobuttons
add(new Checkbox("Red", cbg, false)); // cbg is second argument!!
add(new Checkbox("Green", cbg, false));
add(new Checkbox("Blue", cbg, true)); // Only one in group cbg can be true
