如何解决在我点击 JOptionPane 上的 OK 按钮后，我不知道如何重置第二帧中的所有功能该怎么办？

我使用 JCreator 作为我的 IDE，这个程序有两帧，第一帧是启动帧，你只需按开始，我的问题是在第二帧，我想在我点击时重置该帧中的所有功能JOptionPane 上的 OK 或您有什么建议。它在第 135 行。

                rNumpanel.add(rNum2);   
                scorePanel.add(rScore);
                scorePanel.add(nScore);
                scorePanel.add(time);
                rNumpanel.add(timeBar);
                
         //------------------FRAME----------------------------  
                                        
                dispose();
            }
            i++;
            p.setValue(i);      
        }
}

解决方法

我完成了代码，现在运行良好，我所做的是重置计时器的计数器，然后停止它。

if (timerCounter == 200 ){ 
    JOptionPane.showMessageDialog(this,"Your score is: "+ score +" / "+ count); 
    count = 0; 
    score = 0; 
    rScore.setText(""); 
    randomNum = r.nextInt(1000); 
    rNum2.setText(String.valueOf(randomNum)); 
    timerCounter = 0; 
    t1.stop();
}

最后在第 135 行。我不需要重置 JFrame，只需重置计时器。
