This is a warm-up assignment that uses 2 dimensional arrays to print a Magic Square to the screen of a given size. A Magic Square is a box of numbers where the rows, columns, and diagonals all add to the same sum. You will be given the code for the applet below:

import java.applet.Applet;
import java.awt.*;

public class MSquare1 extends Applet
{

String board[][];
int size;
Label sizeLab;
TextField sizeTxt;

public void init()
{
board = new String[15][15];
sizeLab = new Label("Size?"); add(sizeLab);
sizeTxt = new TextField(); add(sizeTxt);

}

public void paint(Graphics g)
{
for (int r=0; r<size; r++)
{
for (int c=0; c<size; c++)
{
g.drawString(board[r][c],c*15+10,r*15+40);
}
}
}

public boolean action(Event e, Object o)
{
if (e.target == sizeTxt)
{
size = Integer.parseInt(sizeTxt.getText());

for (int x=0; x<size*size; x++)
boardStr(x);

repaint();
}
return true;
}

public void boardStr(int pos)
{
board[pos/size][pos % size] = String.valueOf(pos);
}

}

  Your task is to write a magic square program, which will be an adaptation of the above code. We will go over the rules in class. This is what your finished Applet should run like:
