스레드로 다시 그네 넣기

Question

2 개의 jcomponents, animation 및 gardenpanel이 있습니다. jlayeredpane에 포함 시켰지만 애니메이션 클래스는 항상 움직이는 캐릭터입니다. 주된 방법으로 다시 그리기를 호출 할 때마다 매우 고르지 않고 느립니다. 그래서 Runnable을 구현하고 animation.repaint() 만 호출하는 새 스레드를 시작하는 Update라는 새 클래스를 만들었습니다. 그러나 그것은 아직도 칙칙하고 고르지. 어떤 도움?

public class Driver { 

    public static void main(String[] args) { 
     EventQueue.invokeLater(new Runnable() { 
      @Override 
      public void run(){ 

       JFrame frame = new JFrame(); 
        JLayeredPane pane = new JLayeredPane(); 
        Animation animation = new Animation(); 

       GardenPanel gPanel = new GardenPanel(6,4,600,800); 



       frame.setSize(800,600); 
       frame.add(pane); 
       // establish transparent background 
       //Color transparent = new Color(0,0,0,0); 

       // Initilize jcomponents 
       //Garden garden = new Garden(6,4); 

       //making jcomponents visible 
       animation.setSize(frame.getSize()); 
       gPanel.setSize(frame.getSize()); 


       animation.setOpaque(true); 
       pane.add(animation); 
       pane.add(gPanel); 
       frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
        frame.setVisible(true); 


      } 

     });

    protected class Background implements Runnable{ 

     @Override

Answer 1

Thread background = new Thread(new Background()); 
    //background.setDaemon(true); 
    background.start(); 

하고 Background() 실행 가능한 코드 :

protected class Background implements Runnable{ 

     @Override 
     public void run() { 
      while(true){ <-- it is true, true and true, who is changing it? 

       repaint(); 


      } 
     } 

영원히 repaint() 요청을 호출 , 종료 없음, 아니 sleep 통제. 프로세서에서 몇 사이클이 발생합니까? 귀하의 프로세서는 언제 다른 계산 유닛과 이야기하기 위해 어느 정도 휴식을 취할 것입니까?
