How can I set the initial Delay after pressing the start Button to a specific time (HH:mm:ss) format

this will help Using a JTextField to parse a date format doesn't sound great because the risk of a parse exception will be high. I suggest you to use another component(s), or try to find some external date/time pickers. However, nothing stops you from using java.time API in order to parse the date, calculate the delay and create the timer.
I have created an example:
public class Example extends JFrame {
    private static final long serialVersionUID = 1L;
    private static final DateTimeFormatter formatter = DateTimeFormatter.ofPattern("HH:mm:ss");
    private Timer timer;

    public Example() {
        setLayout(new FlowLayout());

        JTextField field = new JTextField(10);

        JButton startTimer = new JButton("Start");
        startTimer.addActionListener(e -> {
            try {
                LocalTime selectedTime = LocalTime.parse(field.getText(), formatter);
                LocalDateTime selectedDate = LocalDateTime.now().toLocalDate().atStartOfDay();
                selectedDate = selectedDate.plusHours(selectedTime.getHour()).plusMinutes(selectedTime.getMinute())
                // Check if time has passed and should be scheduled for tomorrow
                if (selectedDate.isBefore(LocalDateTime.now())) {
                    selectedDate = selectedDate.plusDays(1);
                long date = Timestamp.valueOf(selectedDate).getTime();
                long delay = date - System.currentTimeMillis();
                timer = new Timer((int) delay, e1 -> {
                    JOptionPane.showMessageDialog(null, "Time passed.");
                System.out.println("Timer started and scheduled at: " + selectedDate);
            } catch (DateTimeParseException e1) {
                JOptionPane.showMessageDialog(null, "Cannot parse date.");

        setSize(300, 300);

    public static void main(String[] args) {
        SwingUtilities.invokeLater(() -> {
            new Example().setVisible(true);

How to start a different activity with some delay after pressing a button in android?

Tag : android , By : Tom D
Date : March 29 2020, 07:55 AM
fixed the issue. Will look into that further You could call a Runnable using the Handler postDelayed() method.
Here's an example (http://developer.android.com/resources/articles/timed-ui-updates.html):
private Handler mHandler = new Handler();


OnClickListener mStartListener = new OnClickListener() {
   public void onClick(View v) {
            mHandler.postDelayed(mUpdateTimeTask, 100);

private Runnable mUpdateTimeTask = new Runnable() {
   public void run() {
       // do what you need to do here after the delay

around this issue Use AsyncTask or Handler for network operations. Do never put "long time" operations into the UI thread

Adding a timed delay after pressing a button to prevent button spam

To fix the issue you can do Say I have 4 buttons , You can use this javascript code:
var btns = document.getElementsByTagName('button');
for(var i=0;i<btns.length;i++){
    btns[i].addEventListener('click', function(){
        setTimeout(function(){disableButtons(false);}, 600);
function disableButtons(state){
    for(var i=0;i<btns.length;i++){
        btns[i].disabled = !!state;    

Start with empty dtPicker Value, then change format after pressing sumbit button

it helps some times When I understand you right, you just need the date in the form "yyyy-MM-dd". Then you could also just read DateFrom.Value and convert it with Format$, like this:
Dim s as string
s = Format$(DateFrom.Value, "yyyy-MM-dd")
MsgBox s

Tag : java , By : Richard Laksana

it fixes the issue There is a Observable.timer(long delay, TimeUnit unit, Scheduler scheduler) in RxJava 2. You can try using that.
