    Question Whats wrong with my code? I tried several things but it still won't work!

    Whats wrong with this code?

    I Tried everything but " super.paintComponent(g); " part still gives the same error

    " - The method paintComponent(Graphics) is undefinedfor the type KeyAdapter "

    import javax.swing.JPanel;
    import java.awt.*;
    import java.awt.event.KeyAdapter;
    import java.awt.event.KeyEvent;
     
    public class Keying extends JPanel{
     
    	public Rectangle character;
     
    	public int charW= 24;
    	public int charH = 36;
     
    	public boolean right = false;
    	public boolean left = false;
    	public Keying(Display f, Images i){ 
    		character = new Rectangle(180, 180, charW, charH);
    		f.addKeyListener(new KeyAdapter() {
    			public void keyPressed(KeyEvent e){
    				if(e.getKeyCode() == KeyEvent.VK_D){
    					right = true;
    					character.x +=1;
    			}
    			if(e.getKeyCode() == KeyEvent.VK_A){
    				left = true;
    				character.x -= 1;
    			}
    		}	
    		 public void keyReleased(KeyEvent e){
    			 if(e.getKeyCode() == KeyEvent.VK_D);
    			     right = false;
    		     if(e.getKeyCode() == KeyEvent.VK_A){
    			     right = false;
    		 }
    		};
    	public void paintComponent(Graphics g){
    		 super.paintComponent(g); 
    		this.setBackground(Color.DARK_GRAY);
    		g.setColor(Color.WHITE);
    		g.fillRect(character.x, character.y, character.width, character.height);
     
    		if(right){
    			character.x +=1;
    		}
    		if(left){
    			character.x -=1;
    		}
    		repaint();
    	}
     
    	private void setBackground(Color darkGray) {
     
    	}
     
     
    	{
    }
    });
    	}}

    Default Re: Whats wrong with my code? I tried several things but it still won't work!

    he method paintComponent(Graphics) is undefinedfor the type KeyAdapter
    The compiler is saying that the super class for the KeyAdapter class does not have a paintComponent() method.

    Is the paintComponent() method in the code defined in the correct class?

    To be sure that the class has a method that can be overridden, add a @Override statement on the line just before the method definition. That asks the compiler to check if the class that the method is in has a method with that name and args.


    One big problem with the code is its poor formatting. The { and }s are not properly positioned to show nested code. Fixing that will show you what the problem is.
    If you don't understand my answer, don't ignore it, ask a question.
