How To Use Timer With JButton
Apr 26, 2015
[attachment=38859:bcourt.jpg]I/m not used to Timers, so this will be my first time using it and I don't know how. I've been searching the internet for an hour but I can't find an answer into it. I'm currently doing a basketball game which has a Buttons (Shoot,Dribble,Hold) and I need those timers for my buttons to work. Her's the code:
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class BasketBall extends JPanel implements ActionListener
{
JButton shootButton = new JButton("SHOOT");
JButton drbblButton = new JButton("DRIBBLE");
JButton holdButton = new JButton("HOLD");
[Code]...

i have a client side program that grabs information about the computer it runs on. I want to have it grab the same info every so often, and check it against the original.
what can be used to do something like that? end game would be having it start up with the pc, then check periodically. if the values are different, send them to the database

One of the classes that i need to serialize includes a few Timers. When I serialize it and then load it up again, the Timers are stopped. How do I start the timers where they left off?I'm using Swing Timers. Should I be using the other kind?
I using the Timers in this case to change something after a countdown, but only once, then the Timers are stopped. I set the Timer tick interval to the time I want it to wait. Should I be using smaller tick intervals, and just waiting for the tenth (or so) tick, or is my way fine?

im making a javabean for stopwatch which works perfectly, but i want in the property descriptor format, so the user can change its format.
currently i have;
private String displayFormat = "MMMM d, yyyy h:mm:ss";
private SimpleDateFormat formatter;
public synchronized void setDisplayFormat(String newFormat) {
String oldFormat = getDisplayFormat();
try {
formatter.applyLocalizedPattern(newFormat);
timerHasPinged();
[code]....
currently the timer works its format is in 00:00 minutes:seconds, but i want it to start as MMMM d, yyyy h:mm:ss, for example March 17 2014 00:00:01, so only one second has passed here. i believe the set and get format method is fine but the timerhaschanged needs to change as this is where the format takes place.

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;
[Code] ....

In my main method I am trying to create a Timer, but when I put new Timer(1000,listener) the constructor is not defined. It is when there is nothing in it. I find this super weird because in all my other programs this does not happen. I looked at the documentation and can't see what I am doing wrong, so I turn here.
ActionClass Java Code: import java.awt.*;
import java.awt.event.KeyEvent;
import java.awt.event.KeyListener;
import java.awt.image.BufferedImage;
import java.io.File;

I am looking for a timer class that can measure how much time has passed since the timer started (like a stopwatch). I don't wan't to use the swing timer because then I would have to create an ActionListener that increments a variable every time an event is created and that seems like too much work for the simple things I want to do. I just want it to have methods for starting the timer, stopping the timer, pausing the timer, restarting the timer, and getting the time.

I'm working on a space invades game and I have a swing timer set up to update the score(number of aliens killed) and for the aliens to shoot. I'm trying to get the score to update at say 100 ms, but the aliens to shoot at 3200ms. I tried to use 2 timers one for the aliens, and one for the score,but the aliens would just use faster score timer.

I'm facing some problem in my EJB setup. I have deployed the ejb setup and it was working fine.
The working conditions are:
1. The timer service is working when i hitted the servlet after starting the server. It must not work when i close the servlet window,but in my case it is still working(timer is performing its opeartion) even i closed the servlet page.
2. When i stopped the server, the timer not gets invoked.
I uninstalled the EJB application, but still the timer service is running.
I'm using WAS 7 server.

I am trying to make a stopwatch using the timer class and JButtons. When I run my program and I hit start the time stays at zero. What I want my stopwatch to do is when I press start it shows the number of seconds that have passed. The start button will then become disabled and the stop button will be the only button able to be pressed. When you hit stop it should enable only the start and restart buttons. Here is my code.
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.*;
public class StopWatchPanel extends JPanel
{private final int DELAY = 1000;

I am making a simple battleship program, you have the menu and click Start to get the board with the bombs (4 buttons as of now) Each button has either a bomb or a defualtbutton. I created my button so it can't be unselected. The problem is I have the button in a Class.java and I want that to close in a period of time. What do you recommend using?

I don't want a tutorial that shows me how to do a util timer with a button, or that prints a message, or that does anything. I want the simplest possible snippet that makes the timer, lets me have it do something, and can be stopped. No bells and whistles, no strings, no sparkles and explosions. Just a timer.
