Lab 2

Due Friday, 9/2 - 11:59pm

  1. Write a for loop to print the multiples of 3 from 300 down to 3.
  2. Implement a class Square.  A Square represents the information about a single square of a Sudoku board.  A Square has the following data members, and get/set methods for each data member:
    1. original - a variable of type boolean to indicate whether the value was set in the original puzzle
    2. set - a variable of type boolean to indicate whether the value has been set by the user, or was set in the original puzzle
    3. value - a variable of type int to indicate the value stored in the square.  if the square has not been set, the value will be 0.
  3. Implement a class Board that has a 9x9 array of Squares as its data member.  Implement a method checkRows in the Board class.  checkRows returns true if every row in the array contains a square with each value 1-9.  For testing, statically set the values stored in each Square of the array.  The signature of the checkRows method is as follows:
    • public boolean checkRows();
        I have created the following skeleton for the Board class to get you started:  This contains two helper methods to initialize the board with some test data.        

Please submit your work in an SVN directory:<username>/cs112/lab2
