}

@Override
public void switchOff()
{
System.out.println("Turning Off.. Samsung TV.");

}

@Override
public void setChannel( int channelNumber )
{
System.out.println("Setting channel Number " + channelNumber + ".. on Samsung TV");

}

}

SonyLedTv.java

public class SonyLedTv implements LEDTV
{

@Override
public void switchOn()
{
System.out.println("Turning ON.. Sony TV.");
}

@Override
public void switchOff()
{

}

@Override
public void setChannel( int channelNumber )
{
System.out.println("Setting channel Number " + channelNumber + ".. on Sony TV");

}

}

AbstractRemoteControl.java

abstract class AbstractRemoteControl
{

protected LEDTV ledTv;

protected AbstractRemoteControl( LEDTV ledTv )
{
this.ledTv = ledTv;
}

public abstract void switchOn();

public abstract void switchOff();

public abstract void setChannel( int channelNumber );

}

SamsungRemoteControl.java

public class SamsungRemoteControl extends AbstractRemoteControl

{

public SamsungRemoteControl( LEDTV ledtv )

{

super(ledtv);

}

@Override

public void switchOn()

{

ledTv.switchOn();

}

@Override

public void switchOff()

{

ledTv.switchOff();

}

@Override

public void setChannel( int channelNumber )

{

}

}

SonyRemoteControl.java

Client.java

public class Client

{

public static void main( String[] args )

{

SonyRemoteControl sonyRemoteControl = new SonyRemoteControl(new SonyLedTv());
