Using A Timer...
Hello, Ive to use a Timer to indicate on System.out.println when two deadlines (to be inputted by user) have been reached. Ive been reading about it for the past hour but ideas would be appreciated, heres my code...
import java.io.*;
import java.net.*;
import java.text.DecimalFormat;
import java.util.*;

publicstatic Calendar deadlineTwo;

Timer timer;
// what follows is the entry of the deadlines
// that need to be indicated when finished
System.out.printf("\nEnter First Item's finishing bid time");
String timeString = BiddingServer.keyboard.nextLine();
String hourString = timeString.substring(0,2);
int hour = Integer.parseInt(hourString);

BiddingServer.deadlineOne = Calendar.getInstance();//Set up Calendar object to hold deadline time...
BiddingServer.deadlineOne.set(year,month,date,hour,minute,0);
