Question:
Write the ideal weight calculator so that height in inches is entered by using a slider. Use the approximate formula:
W = H2 / 30 , for femalehttp://1.bp.blogspot.com/-yJ1RMAmiHSA/TrJ-hXrPHJI/AAAAAAAAATg/GjWP77wAyMg/s1600/cs504.jpg

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).
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.

Note: Your code must justify enough for 15 marks.
