Task 1
Create a Panel instance and add three components to it:
- The label "Java is: "
- A checkbox labeled "Powerful"
- A checkbox labeled "Elegant"
The two Checkbox objects should be under the control of a
CheckboxGroup object.
Add the panel to the applet.
Add a Label instance
first. Then, create a CheckboxGroup object and add the two Checkbox
objects, both associated with the CheckboxGroup object.
Task 2
Register and listen for events in the RadioButtons applet in
order to display the label of the activated checkbox in the TextField
object (already provided). (RadioButtons should implement the ItemListener
interface.)
Fill in method itemStateChanged() so that it sets the text of
the TextField with the method setText(). Use getSelectedObjects()
to get the text of a checkbox's label.
