import javax.microedition.midlet.MIDlet;
import javax.microedition.midlet.MIDletStateChangeException;
import javax.microedition.lcdui.*;

public class ImageEX extends MIDlet implements CommandListener{
  private Command cmdExit;
  private ImageCanvas canvas;
  public ImageEX(){
    cmdExit=new Command("Exit",Command.SCREEN,2);
    canvas=new ImageCanvas();
  }
  protected void startApp() throws MIDletStateChangeException {
    canvas.addCommand(cmdExit);
    canvas.setCommandListener(this);
    Display.getDisplay(this).setCurrent(canvas);
      }


  protected void pauseApp() {
    // TODO Auto-generated method stub

  }

    protected void destroyApp(boolean arg0) throws MIDletStateChangeException {
      }
  public void commandAction(Command command,Displayable screen){
    if (command==cmdExit){
      notifyDestroyed();
      }
    }

}
class ImageCanvas extends Canvas{
  public void paint(Graphics g){
    try{
      Image image=Image.createImage("/ys3.PNG");

      g.drawImage(image,0,0,g.TOP|g.LEFT);}
  catch(Exception e){System.out.println(e.getMessage());}


  }
}
为什么图片不能显示,图片应放在哪里?
还有在编译时出现:
The static field Graphics.TOP should be accessed in a static way
The static field Graphics.LEFT should be accessed in a static way
