Write the ideal weight calculator so that height in inches is entered by using a slider. Use the approximate formula:
W = H2 / 30 , for female
W = H2 / 28 , for male
where W is the ideal weight in pounds,
H is the height in inches
Set an action command for each radio button using [FONT="]setActionCommand(String)[/FONT].
Add an action listener for each button using [FONT="]addActionListener()[/FONT].
Add a change listener for the slider using [FONT="]addChangeListener()[/FONT].
The ideal weight should be displayed in a text field when the user changes either a radio button or the slider.
Pick initial settings for the buttons and slider. When the program starts up display the ideal weight for those settings.
