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.
