Lab Magic Parking Tower

A parking tower is out of order someday. If you park a Benz, you will end up with a Torben. Write a program to simulate this scenario. First create a class called CarParked which has a static method called outOfOrder. Name an object called yourCar, which happens to be a Benz. Your program should contain a class called CarParked and a test program called CarParkedDemo which test the method by CarParked.outOfOrder(yourCar).

Hint: You may study Display 5.14 to get some ideas.

public class CarParked {

private String car;  //p275 3 name改car

public CarParked( String car )

{

this.car = car;

}

public CarParked()

{

car = " No car yet. ";

}

void setCar(String car)

{

this.car = car;

}

public static CarParked outOfOrder( CarParked car )

{

car.setCar( "Torben" ) ;

return car ;

}

public String toString()

{

return car;

}

}

public class CarParkedDemo {

public static void main (String args[]) {

CarParked car = new CarParked( "Benz" ) ;

 

System.out.println("進入停車場的車為" + car);

 

CarParked.outOfOrder( car );

 

System.out.println("離開時的車為" + car);

}
