I have made a small java swing application. And i am showing a count and date.
I want this to refresh after 5 sec.
i have used thread for this.

But it happens that thread sleep and did not invoke again. Can any one please suggest me the way.

Code :

Thread t = new Thread(new DBCount(), "thread 1");
t.start();
for (;;) {
Date date = new Date();
DateFormat nyDf = DateFormat.getDateTimeInstance(DateFormat.FULL, DateFormat.FULL);
DateFormat.getDateInstance();
TimeZone tz = TimeZone.getTimeZone("America/New_York");         
	       
String finaldate = (nyDf.format(date).replace("EDT", "EST"));
System.out.println(DateFormat.getDateTimeInstance(DateFormat.FULL, DateFormat.FULL ).format(date));
id = new DBCount().readQuery(con);
prcs = new DBCount().workerprocess(con);
logger.info(finaldate + ": count - " + id);
labelchange(id, prcs,finaldate, con);
t.sleep(5000);			
}

the reason is your thread has been executed, and you didn't specify any code block inside. If you want to make the thread sleep, you should write code like:

Java

Thread thread = new Thread(new Runnable(){

    @Override
    public void run() {
        // TODO Auto-generated method stub
        for (;;) {
                Date date = new Date();
                DateFormat nyDf = DateFormat.getDateTimeInstance(DateFormat.FULL, DateFormat.FULL);
                DateFormat.getDateInstance();
                TimeZone tz = TimeZone.getTimeZone("America/New_York");

                String finaldate = (nyDf.format(date).replace("EDT", "EST"));
                System.out.println(DateFormat.getDateTimeInstance(DateFormat.FULL, DateFormat.FULL ).format(date));
                id = new DBCount().readQuery(con);
                prcs = new DBCount().workerprocess(con);
                logger.info(finaldate + ": count - " + id);
                labelchange(id, prcs,finaldate, con);
                t.sleep(5000);
                }
    }

});
thread.start();
