wie zu öffnen, ein Jframe von der main-Methode aufrufen

Ich heruntergeladen habe eine Schlange Spiel-Projekt in java und versuchen, es zu ändern. Zunächst wird das Projekt enthält drei java-Dateien
ich.e "Engine.javeine" , "Snake.java", "GameBoard.java". Und Engine.java haben die main() Methode, und wenn ich diese ausführe Engine.java Klasse Spiel beginnt running.

Zur Verbesserung der user iteractivity gegenüber dem Projekt, die ich geschaffen habe zwei JFrames :"PlayGame.java", Rules.java

Nun dieses Projekt mit fünf java-Klassen -

Engine.java(containing main() method) 
Snake.java
GameBoard.java
PlayGame.java(is a JFrame)
Rules.java(is a JFrame)

PlayGame.java have three buttons

Play - i want when play button get clicked snake game start/run.
Rules - when clicked Rules.java Jframe should be opened 
Exit - exits the application

Nun, was ich will, ist auf den ersten "PlayGame.java" JFrame angezeigt werden sollte(und das erscheint als das wichtigste Ergebnis des Spiel-Projekt) und werfen dieses Spiel sollte starten ich.e wenn ich auf play button von PlayGame JFrame Spiel sollte starten
Das problem, das ich bin vor ist, wenn ich auf play - Taste, dann gamescreen erscheint das Fenster aber snake is not moving.

Hier ist der code, den ich in actionPerformed() Methode der Play button

        private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {                                         

            JFrame frame = new JFrame("SnakeGame");
    frame.setVisible(true); 
            frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
    frame.setResizable(true);
    Canvas canvas = new Canvas();
    canvas.setBackground(Color.black);
            canvas.setPreferredSize(new Dimension(GameBoard.MAP_SIZE * GameBoard.TILE_SIZE, GameBoard.MAP_SIZE * GameBoard.TILE_SIZE));
            frame.getContentPane().add(canvas); 
            frame.pack();
            frame.setLocationRelativeTo(null);
            frame.setVisible(true);
            new Engine(canvas).startGame();
}

und auch ich bin anzeigen-code startGame() Methode, die in Engine.java Klasse

public void startGame() {
    canvas.createBufferStrategy(2);

    Graphics2D g = (Graphics2D)canvas.getBufferStrategy().getDrawGraphics();
    g.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);

    long start = 0L;
    long sleepDuration = 0L;
    while(true) {
        start = System.currentTimeMillis();

        update();
        render(g);

        canvas.getBufferStrategy().show();

        g.clearRect(0, 0, canvas.getWidth(), canvas.getHeight());

        sleepDuration = (1500L / UPDATES_PER_SECOND) - (System.currentTimeMillis() - start);

        if(sleepDuration > 0) {
            try {
                Thread.sleep(sleepDuration);
            } catch(Exception e) {
                e.printStackTrace();
            }
        }
    }
}

Hier bin ich auch der Befestigung der Engine.java Klasse und PlayGame.java in meiner Frage zur besseren Verständnis des Problems

möglich, Duplikat der wenn ich auf JButton ich will das Spiel sollte starten

Taht geschieht, weil Sie call
```
new PlayGame().setVisible(true);
```
und
```
frame.setVisible(true); 
```
Zeigen nur den ersten frame und auf den button klicken Sie auf den zweiten.

Der empfohlene Ansatz ist die Verwendung von nur einem frame immer aber mehrere Platten 1. wo das Spiel gerendert wird, und 2. Bereich "Optionen". Tauschen Sie z.B. durch die Verwendung von CardLayout.

Auch nicht verwenden Canvas verwenden JPanel statt überschreiben paintComponent() Methode.
- das ist ok. nun weiter zu mir sagen, wenn ich wollen, um den gameframe auf dem Bildschirm, wenn die play-Taste geklickt wird. für diesen Zweck, welchen code muss ich hinzufügen in der actionPerformed () - Methode der play-Taste ..Ist der gleiche code, den ich.e in main () - Methode Engine.java Klasse oder anderes
- Es könnte der gleiche code. Oder wenn Sie möchten wiederverwenden Rahmen (einmal), dann können Sie halten eine fererence zu den Rahmen-und-machen Sie sichtbar, klicken Sie auf
- genau, ich bin mit dem gleichen code in der actionPerformed () - Methode, aber problem ist, dass die Schlange nicht bewegt und auch die gameframe-Ausgang hängt

Versuchen Sie Folgendes:

JFrameAdd ja = new JFrameAdd();
ja.setVisible(true);
ja.setLocationRelativeTo(null);

Hoffe, es wird helfen!
