Restarting the while loop
<p>I'm trying to restart the while loop. I've declared variable keepGoing of boolean type. If int variable x is off the window, keepGoing changes to false. Then the reset() method have to keepGoing=true. It works but the while loop isn't working.</p>

<p>Class with reset() and checkWin():</p>

<pre><code>private void reset() {
    b.x = 250;
    b.y = 100;
    b.keepRunning = true;
    a.keepGoing = true;
    System.out.println(a.keepGoing);
}

public void checkWin() {
    if (b.keepRunning) {
        if (b.getX() &lt; -10) {
            a.score++;

            JOptionPane.showMessageDialog(okno, "Player " + p.getScore()
                    + " - Computer " + a.getScore(), "Oh, well...",
                    JOptionPane.INFORMATION_MESSAGE);
            b.keepRunning = false;
            a.keepGoing = false;
            System.out.println(a.keepGoing);
            reset();
        } else if (b.getX() &gt; 599) {
            p.score++;
            JOptionPane.showMessageDialog(okno, "Player " + p.getScore()
                    + " - Computer " + a.getScore(), "Good!",
                    JOptionPane.INFORMATION_MESSAGE);
            b.keepRunning = false;
            a.keepGoing = false;
            System.out.println(a.keepGoing);
            reset();
        }
    }
}

<p>Second class with thread, keepGoing and the while loop:</p>

<pre><code>Runnable intel = new Runnable() {
    public void run() {
        while (keepGoing) {
            while (getY() &lt; board.ball.getY()) {
                System.out.println(keepGoing + " " + getY());
                try {
                    if (y == 220) {
                    } else {
                        y += 1;
                        Thread.sleep(10);
                    }
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }
            while (getY() &gt; board.ball.getY()) {
                System.out.println(keepGoing + " " + getY());
                try {
                    if (y == 0) {
                    } else {
                        y -= 1;
                        Thread.sleep(10);
                    }
                } catch (InterruptedException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
            }
        }
    }
};
