loops - Java drawimage in gameloop -

i'm trying learn program first game , understand correctly every step make. i'll face double buffering , other things later. i'm trying load image in game loop. have 2 classes. first it's jframe calling start method. wonder if there ugly code, in here (i think so). so, why images not showing up?

public class mypanel extends jpanel implements runnable{  //fields public static int width = 1024; public static int height = width / 16 * 9; private bufferedimage bg; private bufferedimage charac; private boolean running; private thread t1; private int startposx = width / 2; private int startposy = height / 2; private int cordx = startposx; private int cordy = startposy; int speed = 50;   //methods    public synchronized void start (){     running = true;     t1 = new thread (this);     t1.start(); }  public synchronized void stop (){     running  = false;     try {         t1.join();         system.out.println("the game stopped");     } catch (interruptedexception e) {         // todo auto-generated catch block         e.printstacktrace();               }  }   //init  public mypanel(){     setpreferredsize(new dimension(width, height));    setfocusable(true);    requestfocus();    addkeylistener(this);  }   //main run method   public void run(){            while (running){            load();            system.out.println("the game runs");            repaint();           }  }     //paint graphics method   public void paint (graphics g){     super.paint(g);     g.drawimage(bg, 0, 0, this);     g.drawimage(charac, 110, 280, this);  }  //load images in memory public void load (){             try {         string path1 = "res/bg.png";         bg = imageio.read(new file (path1));         string path2 = "res/charac.png";         charac = imageio.read(new file (path2));     } catch (ioexception e) {          e.printstacktrace();     }  } 

so, did testing paint vs paintcomponent , saw first draws on top of jpanel background. anyway, can't still see changing lines to

    public void run(){     while (running){     load();     system.out.println("the game runs");      } }        //paint graphics method      public void paintcomponent (graphics g){     super.paint(g);     g.drawimage(bg, 0, 0, null);     g.drawimage(charac, 110, 280, null);     } //load images method above 

and yes, i've added panel frame, here other class

public class game {

public static void main (string [] args){  jframe frame = new jframe(); frame.setignorerepaint(true); frame.setdefaultcloseoperation(jframe.exit_on_close); frame.setcontentpane(new mypanel()); frame.pack(); frame.setlocationrelativeto(null); frame.setvisible(true);  mypanel game = new mypanel(); game.start();  }
