[英]Increment an integer in a JTextField by one
我想增加一个JTextField(价值tenSecs
一一为每个实例),我的其他的JTextField( oneSecs
)达到0。我有困难想提高我的价值tenSecs
,因为它始终为0时手动更改了JTextField数字,一旦oneSecs
达到0, tenSecs
还原为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;
线附近int i = 0;
。 我也可以肯定,如果有人可以朝正确的方向指点我,那么增加价值的方法并不是最好的方法
如果我对您的理解正确,请尝试tenSecs.setText(String.valueOf(Integer.parseInt(tenSecs.getText()) + 1));
