**Checker Board**

Make a checkerboard


Write a graphical application that displays a checkerboard with 64 squares, alternating white and black.

Use nested loops.  Hint:  You can add the row and column, and if it is odd make it one color, and if it is even, you can made it the other color.


<code java CheckerBoard.java>
import java.awt.Graphics2D;
import java.awt.Rectangle;

/**
   This class displays a checkerboard with squares,
   alternating between white and black.
*/
public class CheckerBoard
{
   /**
      Creates a CheckerBoard object with a given number of squares.
      @param aNumSquares the number of squares in each row
      @param aSize the size of each square
   */
   public CheckerBoard(int aNumSquares, int aSize)
   {
      numSquares = aNumSquares;
      size = aSize;
   }

   /**
      Method used to draw the checkerboard.
      @param g2 the graphics content
   */
   public void draw(Graphics2D g2)
   {
      // your code here
   }

   private int numSquares;
   private int size;
}

<code java CheckerBoardComponent.java>
import javax.swing.JComponent;
import java.awt.Graphics;
import java.awt.Graphics2D;

public class CheckerBoardComponent extends JComponent
{
   public void paintComponent(Graphics g)
   {
      Graphics2D g2 = (Graphics2D) g;

      final int NSQUARES = 8;

      int size = Math.min(getWidth(), getHeight()) / NSQUARES;
      CheckerBoard cb = new CheckerBoard(NSQUARES, size);

      cb.draw(g2);
   }
}

<code java CheckerBoardViewer.java>
import javax.swing.JFrame;

/**
   This program displays a checkerboard.

public class CheckerBoardViewer

   public static void main(String[] args)
   {
      JFrame frame = new JFrame();

      final int FRAME_WIDTH = 330;

      frame.setSize(FRAME_WIDTH, FRAME_HEIGHT);
      frame.setTitle("CheckerBoardViewer");
      frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
