打开java applet时更改showStatus消息

Question

我正在使用applet编写Java游戏突破。但是当小程序打开时，我想要文本：＆＃34;按下以启动＆＃34;而不是自动＆＃34;小程序已启动＆＃34;。

我知道我可以使用showStatus将消息放入我的代码中（＆＃34;按下以启动＆＃34;）。但我也希望文本立即消失，以便其他文本可以放在那里（例如游戏结束时）。

但是，我不清楚在我的代码中将它放在哪里。这是我的代码。

public class Breakout extends Applet implements Runnable {
    // all the properties are stated here but this is not important for my question and saves a lot of space

    public void init() {
        hitsound = getAudioClip(getDocumentBase(), sound);
        hitsound.play();
        buffer = createImage(FieldWidth, FieldHeight);
        gContext = buffer.getGraphics();
        gContext.setColor(FieldColor);
        brick = new Field();
        paddle = new Paddle();
        ball = new Ball(brick, hitsound);
        gContext.fillRect(0, 0, FieldWidth, FieldHeight);
        paddle.draw(gContext);
        ball.draw(gContext);
        brick.draw(gContext);
    }

    public void start() {
        if(animate == null) {
            animate = new Thread(this);
            animate.start();
        }
    }
    public void restart() { }   

    public void stop() {
        if(animate != null) {
            animate = null;
        }
    }

    public void paint(Graphics g) {
        try {
            g.drawImage(buffer, 0, 0, this);
        }
        catch(Exception e) {}

// In the bottom of the screen the number of lives left is displayed
        g.drawString("Number of lives left: " + (ExtraLives- numberlost), 0, FieldHeight-22);
    }

    public void run() {
        while(true) {
            paddle.clear(gContext);
            ball.clear(gContext);

            if(leftArrow) {
                paddle.move(-PaddleSpeed);
                if(ballready && paddle.moved)
                    ball.move(-PaddleSpeed,0,gContext);
            }if(rightArrow) {
                paddle.move(PaddleSpeed);
                if(ballready && paddle.moved)

            }if(!ballready) {
                ball.moves(gContext,paddle,this);
            }if(brick.bricksLeft()==0)
                win();

            paddle.draw(gContext);
            ball.draw(gContext);

    public boolean getRightArrow() {

有人知道答案吗？
