Help is available for each task.
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.
