I'm currently writing a program that acts as an application for a store manager, sorting, searching, reading in, etc. products. This program has two classes: one to handle the GUI and another to handle the actual calculations. I am completely done coding this, save for one requirement: I need to have the time displayed, and updated every minute. I already have the time displayed; the only problem I have is with having a new time displayed every minute.

I have tried using Thread.sleep(), but this causes my compiler to try and load it, but never succeed in actually bringing up the JFrame.
Right now the code I have for updating the time is as follows:

public void run()
            catch(InterruptedException e){}

and the code I have for getting the time and formatting it for display is as follows:

public String time()
    GregorianCalendar calendar=new GregorianCalendar();
    Date date=calendar.getTime();
    DateFormat type=DateFormat.getDateTimeInstance(DateFormat.SHORT, DateFormat.SHORT);
    String time=type.format(date);
    return time;

I would be very grateful for any help that anyone would be willing to offer. I have searched for how to do this throughout the Internet and have not been able to find it.
