CSI 311L Lab 9, Spring 2012

American University of Science & Technology Department of Computer Science CSI 311L – Java Programming Lab Spring 2011/2012 Lab Work 9 Problem1: Write the classes implementations for the following class specifications. Registered_Vehicle Attribute s  Year: an integer to indicate the registration year.  Plnum: A String to indicate the license_plate number.  type: an integer that can have the value 1(private) or 2(public). Methods  Constructor .  toString: to return the information about a Registered vehicle as follows: (08)-(123456) was registered in 1994 and is a private vehicle.  Get_type: returns the type of a registered vehicle. Remark All attributes should be declared private 1 Write an application to test your classes’ implementations. 2 Car Note that all cars are registered vehicles. Attributes  Brand: a string of characters to store the car brand name.  Color: a string of characters.  Model: an integer to specify the car model number.  Cost: a number to indicate the car basic cost.  Totalprice: It should accumulate the value of all cars’ prices. Methods  Constructor.  Calculate_price: return the price of a car using the following Formula: Price = cost + 300$ if the type = 1. Price = cost + 200$ if type =2.  Get_totalprice: returns the value of Totalprice.  display: to print the information about a car as follows: Mercedes-red-300 (08)-(123456) was registered in 1994 and is a private vehicle. Price = $12500. Problem 2: A. Implement, in Java, the following classes: Bicycle Attributes gear: an integer (from 1 to 5) to specify the gear of the bicycle cost: an integer to specify the basic cost of the bicycle count: to count the number of bicycles Methods Constructor set and get methods toString: to return information about a bicycle computePrice: returns the price of the bicycle by adding to the cost:  $10 for each level of gear MountainBike (a bicycle) Attributes suspension: a String that has the value “Front” if the bike has a front shock absorber or “Dual” if the bike has a front and back shock absorber. Methods Constructor set and get methods toString: to return information about a bike computePrice: returns the price of the bike by adding to price of a bicycle:  $100 if the bike has “Front” suspension  $150 if the bike has “Dual” suspension B. Write a java application to do the following (Use JOptionPane methods):  Create N objects of class MountainBike and let the user initialize them  Display the total number of all bicycles  Display information about all mountain bikes with dual suspension 3
