C. When user clicks Distance Converter, an input dialog will pop up where user can type value and click OK: Welcome to Converter Input X X ? Input miles distance to convert 3.1 OK Cancel Exit Converter d. Once user clicks OK, message dialog will pop up: vert() + Welc Message + X 3.1 Miles equals 4.9879 Kilometers OK e. When user clicks on Temperature button, an input dialog will pop up to input value and then when clicks OK, the message dialog with pop up with converted result: Welcome to Converter Input X ? Input fahrenheit temperature to convert 32 Converter OK Cancel Welcome to Converter Exit Message 32 F equals 0.0 C OK Exit X re Converter f. SUGGESTIONS: For the input dialog you can use JOptionPane.showInputDialog The ActionListener for each Converter button should create the appropriate Converter child instance, set the input, and call its convert() method For the pop up with converted value you can use JOptionPane.showMessageDialog 1/4 | - 100% + Design and implement Java program as follows: 1) Implement converter class hierarchy as follows: a. Converter class which includes: Private attribute for input of data type double Default constructor with no parameter which sets input to Double.NaN Overloaded constructor with input for parameter Get and set methods for input attribute Method convert() which returns input value b. TemperatureConverter class which is a child of Converter and includes: Constructors which call parent constructors Overridden convert() method to convert input (Fahrenheit temperature) to Celsius and returns the value. If the instance has no input value, it should return Double.NaN Use the following formula for conversion: C = ((F-32)*5)/9 c. DistanceConverter class which is a child of Converter and includes: Constructors which call parent constructors Overridden convert() method to convert input (distance in miles) to distance in kilometers and returns the value. If the instance has no input value, it should return Double.NaN d. Use the following formula for conversion: KM = M * 1.609 2) Implement GUIConverter class using JFrame and JPanel as follows: a. GUI will have 3 buttons: "Distance Converter", "Temperature Converter", and "Exit". Welcome to Converter Distance Converter Temperature Converter Exit b. When user clicks Exit, the program will terminate Style and Documentation: Make sure your Java program is using the recommended style such as: Javadoc comment up front with your name as author, date, and brief purpose of the program Comments for variables and blocks of code to describe major functionality Meaningful variable names and prompts Class names are written in upper CamelCase Constants are written in All Capitals Use proper spacing and empty lines to make code human readable Capture execution: You should capture and label screen captures associated with compiling your code, and running a passing and failing scenario for each functionality Submission requirements Deliverables include Java program (.java) and a single Word (or PDF) document. The Java files should be named appropriately, and the Word/PDF file should be named as Assignment3. The word (or PDF) devel
