Question

我正在尝试将JTextfield（tenSecs）的值增加一，以便我的其他JTextfield（oneSecs）达到0的每个实例。我很难尝试增加我的值tenSecs JTextfield，因为它总是为0.当手动更改数字时，只要oneSecs达到0，tenSecs就会恢复为0。

javax.swing.Timer tm = new javax.swing.Timer(1000, new ActionListener() {
    public void actionPerformed(ActionEvent evt) {
        AddOneActionPerformed(evt);
    } 
});

private void StartStopTimerActionPerformed(java.awt.event.ActionEvent evt) {                                               

    if (!tm.isRunning()) {
        tm.start();
    } else {
        tm.stop();
    }

    ScheduledExecutorService e= Executors.newSingleThreadScheduledExecutor(); //Start new scheduled executor service to invoke a timer that start wehn button is pressed
    e.scheduleAtFixedRate(new Runnable() {

        @Override
        public void run() {
            //Follow this Override to do task
            SwingUtilities.invokeLater(new Runnable() {
                //Override will let the task run                

                @Override
                public void run() {
                    oneSecsDisplay.setIcon(new ImageIcon("images\\" + TextGrabber() + ".png"));
                    oneSecs.setText( DigitValue.getText());

                    int i = 0;

                    if (Integer.parseInt(oneSecs.getText()) == i) {
                        tenSecs.setText(Integer.toString(i++));
                    }
                }
            });
        }
    }, 0, 100, TimeUnit.MILLISECONDS); //Update will be for every 100 milliseconds concurrent to system time
} 

// Variables declaration - do not modify   
private javax.swing.JTextField oneSecs;
private javax.swing.JTextField tenSecs;
// End of variables declaration

我确信错误发生在int i = 0;行周围。我也相信，如果有人能够指出我正确的方向，我增加价值的方式并不是最好的方法

Answer 1

如果我理解正确，请尝试tenSecs.setText(String.valueOf(Integer.parseInt(tenSecs.getText()) + 1));

将JTextField中的整数递增1
