java - 将 JTextField 中的整数加一

Question

每当我的另一个 JTextfield (oneSecs) 达到 0 时，我都会尝试将 JTextfield (tenSecs) 的值增加 1。我在尝试时遇到困难增加我的 tenSecs JTextfield 的值，因为它始终为 0。手动更改数字时，一旦 oneSecs 达到 0，tenSecs 就会恢复到 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

我确定错误发生在 int i = 0; 行附近。我也确信我增加值(value)的方法并不是最好的方法，如果有人能指出我正确的方向

Answer 1

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