okey, you know how to get the time from the system, good!

Now you need to do it every 1 sec or what?

then you just make the program "sleep" a while:

try {
  Thread.sleep(1000);
} catch (InterruptedException e) {
   e.printStackTrace();  
}

You can put this into a while(true) block.
like this:

while (true) {
  //Your code to get the time and display it
  try {
    Thread.sleep(1000);
  } catch (InterruptedException e) {
     e.printStackTrace();  
  }
}

At any time, you can just use:

new Date ().getTime ()

to get the time in milliseconds from Jan 1, 1970, right then. So why do you need to keep your object ticking? Whenever you need the time, just make a new object and use the method.

Yes he can, but he could be creating an applet wich displays time, then he needs to update the Applet's clock every second, won't he, so he could use this code to do it:

while (true) {
 //Your code to get the time and display it
 try {
   Thread.sleep(1000);
 } catch (InterruptedException e) {
    e.printStackTrace();  
 }
}
