Description:
PROBLEM STATEMENT:
In the last programming assignment, we broke the bank of the Low Rollers Casino. This time, we will expand on the Slot Machine idea but use a more realistic model, in terms of the slot machineoperation and the cost to payoff averages. In this assignment, you will use class inheritance to define two different types of slot machines. The overall design is shown below in a UML diagram:
SlotMachine(-name-cost-payoff+ pull+getName+getCost)
<-Slot2Wheel Slot3Wheel
InputReader
Assign5(+main)
Note that the SlotMachine class is an abstract class, and its pull() method is an abstract method. You will define two subclasses, the Slot2Wheel and the Slot3Wheel classes, as extensions of the abstract class. Some of the attributes and methods for the abstract class, SlotMachine, are shown in the UML diagram above. You may add more if desired, and you can decide which attributes and methods should be included in the other classes. The only class that will contain a main method is the Assign5 class. All other classes must have constructors. The InputReader class is our old favorite from assignments #3 and #4 and will be provided as before. The name of the input file will be provided as a command line argument.
Deliverables:
*See attached zip file For the detailed description of program. The document is using Microsoft Works -word processor.
Concepts used:
Class inheritance, superclasses and subclasses, creating a new class from an existing class, abstract classes, using the keyword super, understanding polymorphism, casting objects and the instanceof operator, interfaces, arrays (declaring, creating,
initializing and processing them), sorting algorithms, the bubble sort algorithm
Platform:
Java Program (using Windows 98 & Blue J v 1.3.1)Use InputReader.java as follows:
import java.io.*;
/**************************************
* This class opens a file for reading.
* Usage Examples:
*
* // open a file named input.txt
* InputReader myFile = new InputReader("input.txt");
*
* // read a line from the file
* String nextLine = myFile.readLine();
**************************************/
public class InputReader {
static BufferedReader file; public InputReader(String fileName) { try {
file = new BufferedReader(new FileReader(fileName));
}
catch(FileNotFoundException e) {
System.out.println("Error! File not found!");
System.exit(0);
}
}
public static String readLine() {
try {return(file.readLine());}
catch(IOException e){return null;}
}
}

Hello Aaron,
As a Sun certified programmer I can do this assignment very quick after you choose my bid. I will provide a fully commented code.
Best regards,
