Can't call paint() method from another class

Hi, so I'm planning to create a basic game with levels which are each painted from their own seperate level classes. I've made a class called 'Level1' which has the paint method which I want to use in and then also a class which I want to call the method in. When I try to call 'paint(g)' it gives the error g cannot be resolved as a variable.

Here's my code, any help will be much appreciated.

Level1

Code :

---

package maze;
 
import java.awt.*;
 
 
 
import javax.swing.ImageIcon;
import javax.swing.JPanel;
 
 
 
public class Level1 extends JPanel {
 
	private Image wall;
 
	public Level1(){
 
 
	ImageIcon ii = new ImageIcon(this.getClass().getResource("wall.png"));
    	wall = ii.getImage();
 
 
	}
 
 
	public void paint(Graphics g) 
	{
		super.paint(g);			
		Graphics2D g2 = ( Graphics2D )g;   
 
		for(int i = 0; i <= 18; i++){
 
    		g2.drawImage(wall, i*30, 0, this);
    		g2.drawImage(wall, i*30, 540, this);
    		g2.drawImage(wall, 0, i*30, this);
    		g2.drawImage(wall, 570, i*30, this);
    		g2.drawImage(wall, 120, i*30, this);
 
    }
  }
 
 
}

Board

Code :

---

package maze;
 
import java.awt.*;
 
import java.util.ArrayList;
 
import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.Timer;
 
 
import maze.Level1;
 
 
 
public class Board extends JPanel {
 
 
	Level1 level1 = new Level1();
 
	 public Board() {
 
	        setFocusable(true);
	        setBackground(Color.DARK_GRAY);
	        setDoubleBuffered(true);
 
 
	        setSize(400, 300);
 
	        level1.paint(g);
 
	 }
 
 
 
 
}

First, you should override paintComponent, and not paint. Second, you should not call this method directly. Rather, add each component to its parent. This alone when added to a top level component hierarchy is often all that is needed. If you wish to repaint the component, then call repaint(). If you are still having problems, then I suggest posting an SSCCE and describe exactly what the problem is.

Sorry to sound really stupid, but how would I do all that?

The first place I'd start looking would be the Swing Custom Painting Tutorials. I think that most of us learned our Swing graphics starting at this site.

Had a quick look at that and looks very helpful, I'll go through it properly afterschool, thankyou very much!
