* I have to create a GUI class based on JFrame called Assn3.
* Assn4 (My program) should do the following
o be based on a NULL layout
o has 2 JTextFields, one named inputField, the another outputField,
o has a JLabel beside each JTextField holding the names of the fields for the user
o Buttons
+ Clear - empties each JTextField ( hint use setText("") ; )***DONE***
+ Feet to Meters - converts the value in the input field (feet) to meters and displays in the output field. Calls the method ConvertFeetToMeters.
+ Fahrenheit, to Celsius converts the value in the input field (degrees fahrenheit) to degrees celsius and displays in the output field. Calls the method ConvertFarenheitToCelsius
+ Miles to Kilometers, converts the value in the input field (miles) to kilometers and displays in the output field. Calls the method ConvertMilesToKilometers
+ Mach to Miles per hour.
+ Exit - exits the program***DONE***
o Methods
+ convertFeetToMeters, this method should accept one double value as input and return a double value. meters = .305 * feet
+ convertFahrenheitToCelsius, this method should accept one double value as input and return a double value. celsius = (fahrenheit - 32)*5/9.0
+ convertMilesToKilometers, this method should accept one double value as input and return a double value. kilometers = 1.609*miles
+ convertMachToMPH, this method should accept one double value as input and return a double value. mph = mach*770.
