Foil 44 AWT Components -- Checkbox

From Java Tutorial - Spring 1997 Part 3:Graphics and the Abstract Windowing Toolkit Peking Tutorial, Web Certificate -- Spring-Summer 1997. by Nancy J. McCracken,Geoffrey C. Fox
Checkbox's are on-off toggles implemented as
add(new Checkbox("Red"));
add(new Checkbox("Green"));
add(new Checkbox("Blue"),null, true);
The first two are initially set to "false" as the optional third argument is not given. The last one is initially set to "true".
The state of a checkbox, i.e. whether it is checked, is given by the method, getState:
Checkbox cb = new Checkbox("Red");
add (cb);
. . .
if (cb.getState()) . . .;
