You are a car manufacturer assembling a new car model for the US market. Your speedometer supplier, a company in Italy, has shipped a bunch of speedometers to use for the car. Speedometers measure and return the precise speed of the vehicle in km/h. The speedometers have a driver called Speedo that implements the following interface:

public interface SpeedInterface { float getSpeed(); }

The problem is that your digital display, controlled by the DisplayUnit class, is designed to read and display the speed in miles/hour. So you need to convert the reading from km/h to miles/h. The conversion formula is S(miles/h)=S(km/h)*0.62137. Can you use the FULL Adapter Pattern in order to allow this conversion without any change to Speedo and SpeedInterface, and with minimal change in DisplayUnit?

Specifically Implement the solution in Java, by updating and augmenting the starter implementation below. A Converter class is added for your convenience, to be used from within your adapter.

/**

* Interface for speedometer objects

*/

public interface SpeedInterface {

/**

* @return The speed of the vehicle in km/h

*/

float getSpeed();

}

/**

* A stub implementation.

* [Always returns 60 km/h]

* DO NOT CHANGE

*/

public class Speedo implements SpeedInterface {

public float getSpeed() {

return 60;

}

}

/**

* The Client Implementation

* Change as necessary

*/

public class DisplayUnit {

public static void main(String[] args) {

SpeedInterface t = new Speedo();

System.out.println("Current Speed: " + t.getSpeed() + " miles/h");

}

}

/**

* Speed converter for your convenience.

* NOT to be used within DisplayUnit

* @param The speed in km/h

* @return The speed in miles/h

*/

public class Converter {

public double fromKMToMiles(double sp){

return(sp*0.62137);

}

}
