使用Java擺動從一個點移動到另一個

Question

我為對象創建了一個代碼，可以從一個點移動到另一個點。 現在我需要一件事的幫助。 條件是程序應該提示用戶輸入問題，如果用戶正確回答了該問題，則該點應該移動，否則該點應該不移動，並且應該顯示下一個問題，直到所有10個問題都結束為止。 如果用戶到達另一端，則他贏了，否則他輸了。 這是點到點移動的代碼。

                    pointOnTimeLine.y = (int) (startPoint.y + ((endPoint.y - startPoint.y) * i));


                    repaint();

            timer.start();

        @Override

        @Override

            super.paintComponent(g);
            Graphics2D g2d = (Graphics2D) g.create();
            g2d.setColor(Color.RED);
            g2d.fill(new Ellipse2D.Double(startPoint.x, startPoint.y, 10, 10));
            g2d.fill(new Ellipse2D.Double(endPoint.x, endPoint.y, 10, 10));
            g2d.setColor(Color.GREEN);
            g2d.fill(new Ellipse2D.Double(pointOnTimeLine.x, pointOnTimeLine.y, 10, 10));
            g2d.dispose();
        }

    }

}

這是我用來獲取用戶輸入的代碼

import javax.swing.*;
public class input1
{
  public static void main(String args[])
  {
    String str1 = JOptionPane.showInputDialog("france has how many varieties of cheese ? a: 100 b: 200 c: 250");
if(str1.equals("c"))
{
JOptionPane.showMessageDialog( null, "good job ", "answer", JOptionPane.INFORMATION_MESSAGE);
}
else
{
JOptionPane.showMessageDialog( null, "sorry try again ", "answer", JOptionPane.INFORMATION_MESSAGE);
}
}
}

請幫幫我。 提前致謝

 }

    public void paintComponent(Graphics g) {

        int w = getWidth();

        int trainW = 100;

        int x = lastX + trainSpeed;

        gg.setColor(Color.BLACK);
        gg.fillRect(x, h/2 + trainH, trainW, trainH);

      lastX = x;
    }

}

還是謝謝你的幫助...
