Question
CHECK BOXES PROJECT
LANGUAGE: JAVA
Write a program with two checkboxes, one labeled BLUE and the other labeled ORANGE. When no checkbox is selected, the panel’s background color should be gray and its foreground color should be black. When only the BLUE checkbox is selected, the panel’s background color should be blue and its foreground color should be yellow. When only the ORANGE checkbox is selected, the panel’s background color should be orange and its foreground color should be white. When both checkboxes are selected, the panel’s background color should be blue and its foreground color should be orange.
Please note that checkboxes require the use of the ItemListener, as opposed to the ActionListener.
