Elevator Simulation In Event Time Not Clock
Apr 10, 2014I am making a elevator simulator for my class. It needs to be "event time". I am having trouble understanding how I can make an "event time" simulator. Initially I was using a while loop to run a clock time simulation of x seconds for each event, until I ran into a concrete wall and had to call another method which took X seconds, while still needing to execute code.
An example of what I did is:
Spawn person -> person.goToElevator (Takes x seconds) - > person.waitForElevator (Until elevator arrives, x seconds). While this is happening, I needed to create another person and do the same thing, this will add another to the queue if the first person is still waiting. Etc etc, you get the point.
We have not learnt about multi threading, that is the next assignment.
Here is a quote from my lecturer:
"That's right, it requires multi-threading which we're not doing in this paper. Here's a solution that can work:
The person waiting for the lift and then doing lots of other things should do all that in a fraction of a second. So, you don't let the person really wait. Instead, you will set a timestamp in the future in the person object that "he's busy till that time". In all other steps in your simulation you will first check if a person is "busy" (i.e. has a timestamp in the future). If so, you can't use this object, otherwise, you can.
How does it create a bigger queue? Outputs I would have in my final simulation would be, averageQueueLength, numOfPeopleInBuilding etc.
Creating A Clock That Displays Different TIME In Different Capitals
Oct 16, 2014As much as a clock and a calender have to do with date and time, a question arose.
I am creating a clock that displays different TIME in different captials.
Date timestamp = new Date();
timestamp.setTime(timestamp.getTime());
DateFormat time = new SimpleDateFormat("HH:mm:ss");
time.setTimeZone(TimeZone.getTimeZone("UTC"));
System.out.println(time.format(timestamp));
This code, returns the current time in UTC 00:00, the center of the time measuring system. And my program either ADDS an hour to the timestamp or deletes an hour, to make it earlier. My question is: Does Java account for Daylight Savings Time?
On that day, hours shift, and does java shift with them? Is there a changed need to make my code in order to not get the wrong results after the daylight savings time has hit?

Report Employee Time Clock Cannot Find Corresponding Dates In And Out
Mar 8, 2014I have this assignment to build an employee time clock. By using a menu you can enter an employee, enter punch in and out, and report.When I created the punch screen I wrote the in and out records to a file. Because there can be several employees punching in or out the file wrote each occurrence on different lines. Now I am attempting to write the report which you enter an employee Id and loop through the file to find the in and out date and then calculate the time (hours worked). I loaded the file into an Arraylist but now I cannot figure out how to loop through find the In and Out date - calculate the hours worked and then move on to the next day. here is the format of the file - employee id, place holder I or O, date, time, day. and sample

Getting User Input Second Time
Apr 19, 2014I'm working on creating a dice game and getting the users input is giving me a really hard time. I have the main game working but this part I'm stuck on. The problem is that it's not giving me the chance to enter the second input when I ask for the game.
//Create Scanner object
Scanner keys = new Scanner(System.in);
//Get chips
System.out.print("How much money would you like to change? ");
int chips = keys.nextInt();

Java Program That Will Ask A User To Input Grades Until User Inputs Sentinel Value
Apr 9, 2014Write a java program that will ask a user to input grades until the user inputs the sentinel value -1. The program should test each input to determine whether 0<=grade<=100. If the grade entered is within this range, the program should print "Grade accepted;" if not, the program should print "Invalid input".

Create A Countdown In Java
Feb 24, 2014 I'm making a small play in java in which you have a limited time to make as many moves as possible (with the aim of achieving a maximum score), like this: URL...
In the game panel I see the map on which you will perform the moves and a score indicator constantly updated. I have to add the indicator that shows me the passage of time (first 3 minutes), in digital format mm: ss. I thought I will be a useful thread called Countdown because I have to stop this counter if the user presses the pause button in the game. Then wanting to continue the game shall resume the countdown.

Time - Cannot Input Any Value Into Parameter Without It Returning Error

CountDigitx - Take Two Integers As Input And Return How Many Time X Occurs In Number N
Apr 29, 2014Write a recursive Java method countDigitx that takes two integer numbers as input (a number n and digit x) and returns the number of times digits x occurs in number n:
For example if n=23242 and x=2 then the method should return 3 that is the number of times the number 2 found in n.
Thread And Clock Management
Dec 19, 2014I have objects (baddies in a game) that have individual clocks/counters assigned to them (when I make an object, I fill an integer based array list with a new digit entry at a value of one) that all happens in threads. then in another thread, I am checking the whole list of clocks, to see if any are equal to a wanted value , then I am taking an action and reseting the clock at that point on the array list.
now, the problem is:even though my code says " yes, I've taken that action because the value of array position x was >= specified value and I will now reset the clock" it doesn't reset the clock. Here is what it looks like
*these are excerpts taken from a really big program, however they should stand on their own as they are individual classes

public class levelclock extends Thread {

try {
Thread.sleep(100);
} catch (InterruptedException e) {
