this ();

System.out.print(“FourWheelDrive(int),”);

}

FourWheelDrive(){

System.out.print(“FourWheelDrive(),”);

}

FourWheelDrive(int wheels, String make){

this(wheels);

System.out.print(“FourWheelDrive(int,String),”);

}

public static void main (String args[]){

Vehicle v = new FourWheelDrive(2,“Beetle”);
