How To Implement Clock / Timer In Java

Jun 10, 2015

How do I impliment a clock/timer in Java? The program saves files in memory for future use. I've included part of the program below I'd like to add a timer to check if the file was changed every 10 minutes. I have included part of the program below.
 
static FastDateFormat fastDateFormat = FastDateFormat.getInstance("MM/dd/yy HH:mm:ss"); 
  private static final class FileContentsObject {
  private long cachedTime; // currentTime
  private long lastModifiedTimestamp;
  private List<String> contents;

Timer Conversion On JApplet - Implement 6 Seconds Delay Before Every Loop

Jul 7, 2014

So I'm trying to make an applet and I found that Thread.sleep() to simply delay is a bad idea.

I'm not sure how to use the Timer class to implement a same version of sleep() to delay 6 seconds. I am trying to do this in a for loop to delay before every loop. How can I implement this?

This code is after the init() method. For simplicity I didn't include. Assuming I did:

Timer t = new Timer(6000, null);
public void actionPerformed(ActionEvent e) {
try {
URL rsUrl = new URL("http://rscript.org/lookup.php?type=namecheck&name=" + n1);
BufferedReader br = new BufferedReader(new InputStreamReader(rsUrl.openStream()));
for (count = 0; count < maxCount; count++) {

Using A Timer In Java Quiz

Apr 17, 2014

I am currently making a quiz for a project. I am almost finished, but I need to use a timer.

Here is what I want to happen:

The user to has 15 seconds to answer each question. If they answer, they are given the option to move to the next question, or leave the quiz. If they answer incorrectly, the quiz closes. If they do not answer within the 15 seconds, the program treats this as an incorrect answer, and the quiz closes.

Here is a section of the quiz code which includes the start of the code to the end of the code for the first question:

Java Code:

package quiz;
import java.awt.Graphics;
import java.awt.Image;
import java.awt.image.BufferedImage;
import java.util.Scanner;
import javax.swing.AbstractButton;

Java Timer - GUI Button Not Linking Back To Code

Jan 12, 2014

I have started coding recently and been working on a simple java timer. My problem is that the button does not show any response even though an action has been done via actionlistener.

Example: When I press the "Start Timing" button, it should start timing and output the counter to Static Timer but instead of doing that, it does nothing.

The important bits are under Timer code and Button Start Timing. Is their something that I'm missing?

//--- All imports have been handled ---
public class GUI {
double counter = 1;
double inputA = 1;
int delay = 1000;
Timer timer = new Timer(delay, null);

Swing/AWT/SWT :: Stopwatch - User Select How Timer Format Is On Java Beans

Mar 17, 2014

I am working on a java bean, on a stopwatch

private String displayFormat = "%02d:%02d:%02d";// produces 00:00:00 hour:min:seconds
public void timerHasChanged() {
currentTime = System.currentTimeMillis();
// How long has been taken so far?
long secsTaken = (currentTime - startTime) / 1000;
long minsTaken = secsTaken / 60;
secsTaken %= 60;
long hoursTaken = minsTaken/60;
minsTaken %= 60;

Formatter fmt = new Formatter();
fmt.format(displayFormat, hoursTaken, minsTaken, secsTaken);
timerJbl.setText(fmt.toString());

How would i code the get and set method for format, so in property tab a user can choose if they want the timer shown in seconds, or minutes or hours or seconds&minutes

Thread And Clock Management

Dec 19, 2014

I 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

Java Code:

public class levelclock extends Thread {
public void run() {
while (Run2 == true) {
if (Run == false) {
try {
Thread.sleep(100);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();

Elevator Simulation In Event Time Not Clock

Apr 10, 2014

I 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, 2014

As 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, 2014

I 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

111221111i3/2/145:10 PMSunday
111221111o3/2/145:10 PMSunday
111331111i3/2/145:25 PMSunday
111331111o3/3/1412:47 PMMonday
111221111i3/3/1412:48 PMMonday
111221111o3/3/142:23 PMMonday
111441111i3/4/141:30 PMTuesday

[code]....

here is my code from the main screen.

public static void displayPunches()
throws FileNotFoundException, IOException, ParseException {
boolean isValid = false;
String choice = "y";
String emp = Validator.getLine(sc, "Enter I -Individual or A -All ");

Swing/AWT/SWT :: Implement CSS In Java Via A JEditorPane

Aug 5, 2014

I'm trying to implement CSS in Java via a JEditorPane and an HTMLEditorKit. The CSS is included below. It *should* create a container with one on the left, small, and one on the right, large. It works flawlessly on JSFiddle [URL] ...., but on Java, it won't put the two divs next to each other. Is this a problem in Java/Netbeans or is it my problem? It creates the divs, but beneath each other. The JEditorPane is wide enough for all of them to fit.

Coding:

Java:
private void loadBulletins() {
//<editor-fold defaultstate="collapsed" desc="HTML/CSS Script">
String eBullStyles = "#divMsgs{ "
+ "height: 99px; "
+ "margin: auto; "
+ "background-color: #3399FF; "

Java Interface - Implement Method In Another Class

Sep 17, 2014

So I created an interface which has the method

int getCalls();

I am trying to implement this method in another class but I'm not sure how to do so. My attempt is:

public getCalls(){ return getCalls(); }

When I run the program it sends the following exception:

Exception in thread "main" java.lang.StackOverflowError
at FibonacciForget.getCalls(FibonacciForget.java:14)
and it highlights the [return getCalls();] part.

What is the correct way to implement the getCalls() method?

Java Servlet :: Implement Session Timeout For Users

Dec 7, 2012

Coding a web application using Java 6. Try to implement the session timeout for users.

In the web.xml, I added:

<session-config>
<session-timeout>480</session-timeout> <!-- jsp will expire in 8 hours -->
</session-config>

Now, during the runtime, if a user does not touch the jsp page for 8 hours (after the user has signed in), the session timeout mechanism will kick in. At that point, the server side will automatically execute:

rd = req.getRequestDispatcher("/signin.jsp");

So that the user will have to re-sign in, before continue the work.

How can I achieve this goal?

Java Program To Implement A Single Linked List Structure

Jul 27, 2014

I'm trying to build a program that contains the ability to:

(1) insert new node at head,
(2) print out contents of the list in order,
(3) remove first node from head,
(4) remove last node from tail,
(5) find a target value,
(6) give total number of occurrences of a target value, and
(7) give total number of items in list.

The areas I'm struggling with implementing are: (

- remove from tail - I know how to find the final node but I can't quite figure out how to set it to null since its initial type is an integer.
- find a target value - how to make the parameters quite workout so the user can simply input an integer value.
- The solution is probably really simple but I can't figure out how to print out the results of these methods when I call them.

public class Node
{
private int data;
private Node link;
// Node Constructor 1
public Node()
{
data = 0;
link = null;
