CDA4101, Assignment 3

Due 10/28 at the start of class

Write a Java program for problem 43 in the Chapter 3 exercises. Make the following adjustments

• You may work in teams of two for this project. If you decide to do this, please notify me via e-mail of who the team members are.
• This is a perfect example for using OO design.
  • All pins look the same. They can be set, and they contain a list of other pins that they are connected to.
  • All gates have an output pin and at least one input pin. All gates could be derived from such a class. All two-input gates could be derived from a class that has an additional input pin. There could be a heirarchy of gates: Gate - Two Input Gate - Three Input Gate - etc.
  • You need three types of gates for this assignment: input, output, nand.
• Read the number of rows, columns, input and output from the wire specification file.
• Create a GUI interface. Use a Canvas to draw the truth table for the circuit. Use a Choice to list all the files in the default directory. Do not hard code the name of the directory.
• Create wire spcifications for the following:
  • NAND gate
  • AND gate
  • OR gate
  • Majority function
  • The PLA question from HW1.
• Create a package named GateArray. Place all your .java and .wspc files in this package. Upload a zip archive of the complete package.
• Create JavaDoc documentation for your project. In the documentation, indicate who was the author of each method that you create.
• Each method cannot exceed 25 lines of code. The only exception is the paint method.
