create an application that converts a temperature from Fahrenheit to Celsius or from Celsius to Fahrenheit. The application should have a GUI interface as described in Chapter 15 that permits the user to enter a temperature in either Fahrenheit or Celsius and displays the corresponding temperature in the opposite scale. The user should be able to enter a temperature in either scale. At minimum, the interface should include options to refresh (clear) the form, calculate and display the corresponding temperature, and Exit. To keep things compatible create all required classes in one file.
