Thread: Timer Class (How to reschedule)

I have the following code that works in that I can enter the hour, min and sec and it will wait until this time to run the code.

What I need is to be able to run this permanently and for it to run at 7am every morning (except saturday and sunday).

How can I alter this code to achieve the following, I also need to have this in its own thread due to other objects running their own code within the same package

import java.util.Timer;
import java.util.TimerTask;
import java.util.Calendar;
import java.util.TimeZone;
 
 
public class MyTimer 
{
    Timer timer;
    Calendar startTime;
 
    public MyTimer(int seconds) 
    {
        startTime = Calendar.getInstance(TimeZone.getDefault());
        startTime.set(Calendar.HOUR_OF_DAY, 20);
        startTime.set(Calendar.MINUTE, 56);
        startTime.set(Calendar.SECOND, 00);
        timer = new Timer();
        timer.schedule(new RunTask(), startTime.getTime(), 1000 * 60 * 60 * 24);
    }
 
    class RunTask extends TimerTask 
    {
        public void run() 
        {
            System.out.println("It's Time");
            timer.cancel(); //Terminate the timer thread
        }
    }
 
    public static void main(String args[]) 
    {
        new MyTimer(5);
        System.out.println("Waiting");
    }
}

Thanks, used the calendar class and works fine
