I want to loop something according to time.

I.e. suppose if time right now is 12:00 AM

I want the loop to run every 1 minute till the time is 12:30 AM  for
instance.

Pseudo-code below

While(Time != 12:30 AM)                                    /// <-----
But I want this loop for run every minute
{  System.out.println("Time right now is " + time);
}

How would I code something like that in Java
?
