Radio buttons are used to specify mutually exclusive options. Check boxes are similar to radio buttons, but are used to specify options that not mutually exclusive. Any combination of check boxes can be checked at one time. A check box is created from the JCheckBox class. Add two check boxes to the Cl8h5. java (acopy of GUI5 in Fig. 18.7) program, one on each panel, that control the background color of its panel. When a checkbox on a panel is checked, the background color on that panel should go white. When unchecked, the background color should revert to its original color (yellow for panel1 or green for panel2).

Explanation / Answer

the condition wich is used for radio buttons can be used for the check boxes if true than set bg color is white other wise take the bsic color of panel 1 or 2
