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 setActionCommand(String) just as for push buttons. Add an action listener for each button using addActionListener(). Add a change listener for the slider using addChangeListener(). 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.
