java - How to stop an applet from blinking? -


i have been trying convert 1 of games applet since first time using applet ran problem. whenever open game screen start blinking. i'm pretty sure due not having bufferstrategy whenever try create 1 "bufferstrategy bg = this.getbufferstrategy()" doesn't work. can help?

package main;  import java.awt.color; import java.awt.graphics;  import javax.swing.japplet;  import handling.handler; import other.hud; import other.keyinput;   public class game  extends japplet implements runnable{      private static final long serialversionuid = 9021342660060318393l;      public static final int width = 640;     public static final int height = width / 12 * 9;      private thread thread;     private boolean running = false;      private handler handler;     private hud hud;     private spawner spawner;     private menu menu;      public enum state{         menu(),         help(),         settings(),         deathscreen(),         game();     };      public enum difficulty{         easy(),         mediuŠ¼(),         hard();     };      public state gamestate = state.menu;     public difficulty difficulty = difficulty.easy;            private void tick(){         handler.tick();         if(gamestate == state.game){             hud.tick();             spawner.tick();         }else if(gamestate == state.menu){             menu.tick();         }     }      public void paint(graphics g){          //draw here         g.setcolor(color.black);         g.fillrect(0, 0, width, height);          handler.paint(g);          if(gamestate == state.game){             hud.paint(g);         }else if(gamestate == state.menu || gamestate == state.help || gamestate == state.settings || gamestate == state.deathscreen){             menu.paint(g);         }         //stop drawing          g.dispose();     }             public void init(){         setsize(width,height);          handler = new handler();         menu = new menu(this, handler);         this.requestfocusinwindow(true);         this.setfocusable(true);         this.addkeylistener(new keyinput(handler));         this.addmouselistener(menu);         hud = new hud();         spawner = new spawner(handler, hud, this);     }      public void start(){         thread = new thread(this);         thread.start();         running = true;     }      public void destroy(){}      public void stop(){         try {             system.exit(1);             thread.join();             running = false;         } catch (interruptedexception e) {             e.printstacktrace();         }      }      public void run() {         this.requestfocus();         long lasttime = system.nanotime();         double amountofticks = 60.0;         double ns = 1000000000 / amountofticks;         double delta = 0;         long timer = system.currenttimemillis();         int frames = 0;         while(running){             long = system.nanotime();             delta += (now - lasttime) / ns;             lasttime = now;             while(delta >= 1){                 tick();                 repaint();                 delta--;             }             frames++;              if(system.currenttimemillis() - timer > 1000){                 timer += 1000;                 system.out.println("fps: " + frames);                 frames = 0;             }             try {                 thread.sleep(20);             } catch (interruptedexception e) {                 e.printstacktrace();             }         }         stop();     }  }

instead of calling repaint(), try call 

paint(getgraphics()).

another thing, add method applet: 

public void update(java.awt.graphics g) {}
