Question

我有一个问题，我的JFrame不断闪烁白色和黑色，但我只将颜色设置为黑色。我认为这与while（running）{}位有关。

它永远变成白色和黑色，直到我关闭它。我真的不知道发生了什么..我刚刚开始使用JFrame所以我确定我刚刚放了一些错误的代码。

public class Game extends Canvas implements Runnable {

    private static final long serialVersionUID = 1L;

    public static int width = 300;
    public static int height = width / 16 * 9;
    public static int scale = 3;
    public static boolean running = false;

    private Thread thread;

    private JFrame frame;

    public Game() {
        Dimension window = new Dimension(width * scale, height * scale);
        setPreferredSize(window);
        frame = new JFrame();
    }

    public synchronized void start() {
        running = true;
        thread = new Thread(this, "Display");
        thread.start();
    }

    public synchronized void stop() {
        try {
            running = false;
            thread.join();
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }

    public void run() {
        while (running) {
            render();
        }
    }

    public void update() {

    }

    public void render() {
        BufferStrategy buffer = getBufferStrategy();

        if (buffer == null) {
            createBufferStrategy(3);
            return;
        }

        Graphics g = buffer.getDrawGraphics();

        g.setColor(Color.BLACK);
        g.drawRect(0, 0, getWidth(), getHeight());

        g.dispose();
        buffer.show();
    }

    public static void main(String[] args) {
        Game game = new Game();

        game.frame.setResizable(false);
        game.frame.setTitle("Game");
        game.frame.add(game);
        game.frame.pack();
        game.frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
        game.frame.setLocationRelativeTo(null);
        game.frame.setVisible(true);

        game.start();
    }
}

我自己解决了......我使用了方法drawRect（）我阅读了文档页面，它说它只绘制了矩形的轮廓..所以我只是做了drawRect（）我还将缓冲区更改为2.

抱歉浪费你的时间。
