Checking the time before code execution..

Question

public boolean checker(int mins) {
          int minutes = 0;
          while (mins!=minutes) {
               Calendar cal = new GregorianCalendar();
                   minutes = cal.get(Calendar.MINUTE);
          return true;
     }I am building a time-sensitive embargo application which will run in the background and constantly check the time until a certain time is reached when it will automatically update a website by sending a file by ftp.
The above method is the time checker which, when called, will only allow the ftp code to execute when it returns - which is when the required time (in minutes) is reached.
My question is this: Is this the best way to achieve this or will it tie up valuable resources. Can anyone suggest a better way ?
Thanks

Answer 1

import java.util.Timer;
import java.util.TimerTask;
  * Simple demo that uses java.util.Timer to schedule a task to execute
  * once 5 seconds have passed.
public class Reminder {
     Timer timer;
     public Reminder(int seconds) {
         timer = new Timer();
         timer.schedule(new RemindTask(), seconds*1000);
     class RemindTask extends TimerTask {
         public void run() {
             System.out.println("Time's up!");
       timer.cancel(); //Terminate the timer thread
     public static void main(String args[]) {
   System.out.println("About to schedule task.");
         new Reminder(5);
   System.out.println("Task scheduled.");
}
