}

class Bear extends Mammel
{


}

class Elephant extends Mammel implements Vhicle
{
public void drive()
{
System.out.println("Elephant Called");
}

}

class Horse extends Mammel implements Vhicle
{
public void drive()
{
System.out.println("Horses Called");
}
}

class Lion extends Mammel
{

}

class TestMammel
{
public static void main( String args[] )
{

Horse h = new Horse();
Elephant e = new Elephant();

h.drive();
e.drive();

}
