Adapter Design Pattern – Implementation [Mobile Charger] - Class Diagram




























Volt.java

public class Volt
{
private int volts;

public Volt( int v )
{
this.volts = v;
}

public int getVolts()
{
return volts;
}

public void setVolts( int volts )
{
this.volts = volts;
}
}


ElectricSocket.java

public class ElectricSocket
{
public Volt getVolt()
{
return new Volt(120);
}
}


ITarget.java

public interface ITarget
{
public Volt get9Volt();
}


MobilePhoneCharger.java

public class MobilePhoneCharger implements ITarget
{

private ElectricSocket electricSocket = new ElectricSocket();

@Override
public Volt get9Volt()
{
Volt volt = electricSocket.getVolt();
System.out.println("From ElectricSocket MobilePhoneCharger got :" +volt.getVolts() + "v");
Volt convertedVolt=convertVolt(volt,13);
System.out.println("\nMobilePhoneCharger converterd "+volt.getVolts()+"v to "+convertedVolt.getVolts()+"v\n");
return convertedVolt;
}
private Volt convertVolt(Volt v, int i) 
  {
       return new Volt(v.getVolts()/i);
}

}


MobilePhone.java

public class MobilePhone
{

public static void main(String args[])
{
new MobilePhone().chargeMe();
}
public void chargeMe()
{
ITarget target = new MobilePhoneCharger();
Volt volt=target.get9Volt();
System.out.println("Mobile phone is charging using : "+volt.getVolts() + "v");
}
}


Output

From ElectricSocket MobilePhoneCharger got :120v

MobilePhoneCharger converterd 120v to 9v

Mobile phone is charging using : 9v
