HOW TO include button below sudoku puzzle? please help

-----------------------------------

I have my basic sudoku program here (it hasnt been able to solve yet). After the user presses level 1, they will be taken to the puzzle itself. 

I want to include a button below the puzzle. But everytime I try doing so, it messes up the order of the rows and columns. Can someone please help me create a JButton below the puzzle?

thanks

[code]import java.awt.Button;

public class practice extends JApplet implements Runnable, ActionListener{

	JButton num0 = new JButton("Start Level 1");
	JButton num1 = new JButton ("start level 2");
	JPanel p = new JPanel();
	

	Font firstFont = new Font("Times New Romans", Font.PLAIN, 20);


	public static final Component dialog = null;


	/** declares the array for the three different levels */
	public int level1[][] ;
	public int level2[][];
	public int level3[][];

RE:HOW TO include button below sudoku puzzle? please help

-----------------------------------

Didn't read most of your code, but if you want a button at the bottom, try this:


public void init()
{
  p.setLayout(new BorderLayout());
  p.add(num0, BorderLayout.SOUTH);
  num0.addActionListener(this);             
}


You didn't put p.add(num0); Try adding the button to the panel p, you just put add, but no p.add...

You could also try p = (JPanel) frame.getContentPane();

^ For your frame, whatever it may be.



You could also try setting the frame visible to true At the end of the constructor, if nothing else works.

I know a few people in my class who copied my code after I pasted it, so in case my teacher checks this website, R.W. (intiails) wrote this...
