Apr 17, 2014I 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.

Java Timer - GUI Button Not Linking Back To Code
Jan 12, 2014I 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?

public class GUI {
double counter = 1;
double inputA = 1;
int delay = 1000;

Swing/AWT/SWT :: Stopwatch - User Select How Timer Format Is On Java Beans
Mar 17, 2014I 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
Military Time - Adding Minutes Displaying Correct Time
Feb 9, 2015I am working on an assignment that I can't seem to figure out the final part to. The program takes in course data such as the time the class starts and how long it lasts. The time is in military time (0000 - 2400)
I need the output time to be the time the class started, plus the length of the class, and displayed in military time.
for example,
Start Time = 0930
Length = 50 minutes
Endtime = 1020
I can't for the life of me figure out how to do this. I have gotten a program that works for this time and minutes, and displays the correct 1020. But when I change the information to say
Start time: 0700
Length = 90 minutes
I get:
Endtime = 90
90 is technically correct, the way the formula is setup, but I need it to display 0900 not 90.
Here is the code that I have. Be easy, I'm still learning, and this is just the file I created to get the formula to work. Also, the verbose in here is just for my own debugging to make sure values should be what I'm expecting them to be.
public class calc
{
public static void main(String[] args) {
double hours, minutes, length;
double temp;
int time = 2400;
hours = time / 100;
System.out.println("Hours are: " + hours);

Does Java Extend 2 Classes At One Time
Feb 7, 20141) when you create a class and compile it and open and see the class using javap command .. that class file contains that it extends java.lang.object and a default constructor is created automatically..... But when you extends another class the java.lang.Object class is not appeared as extended why?
Code example:
1St Case ----- Java code:
public class temp(){
}
Javap Code:
public class temp() extends java.lang.Object {
public temp(){
}
}
2nd case --- Java Code:
public class temp() extends dummy{
}
javap Code:
public class temp() extends dummy{
public temp(){
}
}
why for the above scenario it doesn't extends object class .. if it does implicitly then why it did not do in the first case instead why did the compiler extends Object class ?
How To Add Interactive Time Delay In Java
Nov 16, 2014I'm trying to write a program the simulates the time delay of an elevator door and I want to know how I can add an interactive time in delay in Java.
I know that this is how you delay a Java program:
try {
Thread.sleep(60000);
}
catch(InterruptedException ex) {
}
But how can I make it so that the user can make the timer last longer or end faster through user input.
Converting Military Time To Standard Time?
Jan 29, 2014I have two classes. time_runner is used for testing my code.
This is what I'm using to test my code:
class time_runner
{
public static void main(String str[]) throws IOException {
Time time1 = new Time(14, 56);
System.out.println("time1: " + time1);
System.out.println("convert time1 to standard time: " + time1.convert());
System.out.println("time1: " + time1);
System.out.print("increment time1 five times: ");
time1.increment();
[code]....
The two constructors are "Time()", which is the default constructor that sets the time to 1200, and "Time(int h, int m)" Which says If h is between 1 and 23 inclusive, set the hour to h. Otherwise, set the hour to 0. If m is between 0 and 59 inclusive, set the minutes to m. Otherwise, set the minutes to 0. Those are my two constructors that I pretty much have down. The three methods however I'm having trouble with. The "String toString()" Returns the time as a String of length 4. The "String convert()" Returns the time as a String converted from military time to standard time. The "void increment()" Advances the time by one minute.
public class Time {
private int hour;
private int minute;
public Time(int h, int m) {
if(h > 1 && h < 23)
hour = h;

Swing/AWT/SWT :: Calculating Time And Speed In Java GUI
Sep 27, 2014So i'm using Netbeans and have created this template for the program i want to create. Basically what I want to do is enter a time and date in 24hr format including seconds and the date of start and end time and have the program calculate the time difference between Tool launch and tool Receive that takes into factor the Launch and Receive Dates for a total of hh:mm:ss duration. I don't know how to combine both those factors output one number in a total number of hours Duration. I'm also having problems linking the ODO (odometer) which the formula would basically be time/ODO (or distance in feet) = x.x ft/sec format.

Java Time Zone Transition Period From EDT To EST?
Oct 28, 2014Problem statement: Convert "2014-11-02 01:00:15 EST" to GMT.
This seems easy enough. But why is the below code giving the wrong answer?
Background:
* EDT aka GMT-4
* EST aka GMT-5
* 2014-11-02 01:00:15 EST == 2014-11-02 06:00:15 GMT
* If I user the commented out date string it works!!!
* EDT(until Nov 2, 2014 at 2am) -> at 2am we go to 1am EST
* If I use the below commented out from string it work!!! But these are equal (2014-11-02 01:00:15 GMT-05:00 and "2014-11-02 01:00:15 EST)
Code Example:
ZoneId gmt = ZoneId.of("GMT");
//String from = "2014-11-02 01:00:15 GMT-05:00";
String from = "2014-11-02 01:00:15 EST";
final DateTimeFormatter dateTimeFormatterone = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss z");
ZnedDateTime zonedDateTime = ZonedDateTime.parse(from, dateTimeFormatterone);
ZonedDateTime gmtzonedDateTime = zonedDateTime.withZoneSameInstant(gmt);
String result = gmtzonedDateTime.format(dateTimeFormatterone);
This is what the outcome is.
result == "2014-11-02 05:00:15 GMT"
Shouldn't it be
result == "2014-11-02 06:00:15 GMT"

Java Convert String Of XML To Document Object Is Null All The Time
Apr 14, 2014I am trying to parse a XML string into `org.w3c.dom.Document` object.
I have looked at solutions provided [here](xml - How to convert String to DOM Document object in java? - Stack Overflow), [here](How to create a XML object from String in Java? - Stack Overflow) and a few other blogs that give a variation of the same solution. But the `Document` object's #Document variable is always null and nothing gets parsed.
Here is the XML
XMLMappingValidator v = new XMLMappingValidator("<?xml version="1.0" encoding="utf-8"?>
" +
"<mapping>
" +
"<container>
" +
"<source-container>c:stem.csv</source-container>

Java 2D Game - Overcoming Max Of Three Keys At A Time Limitation Of Keyboard
Jan 7, 2014I'm working on a Java 2D game which requires a max of six keys be held down at the same time.
The game is for two players on the same keyboard, playing simultaneously.
However, all three computers I ran the program on only allow a max of three keys held at a time. They all have trouble with reacting to more than three keys being held.
It seems that pressing a new key after three are already held, either cancels some other key-holding or is ignored.
I've been told that this is a hardware issue. Most keyboards can't handle more than three keys held at a time. But a lot of games do require this, and they do not require special gaming-keyboards to run on my computer without problems.
So there has to be a solution that will make the game playable on any standard keyboard.
(I use Key Bindings).
The game's controls:
Player 1
- Rotate sprite and set angle of movement: LEFT arrow
- Rotate sprite and set angle of movement: RIGHT arrow
- Move forward: UP arrow
- Shoot missile: ENTER key
Player 2
- Rotate sprite and set angle of movement: 'A' key
- Rotate sprite and set angle of movement: 'D' key
- Move forward: 'W' key
- Shoot missile: 'T' key
Relevant code:
The Key Bindings part:
Java Code:
// An action for every key-press.
// Each action sets a flag indicating the key is pressed.
leftAction = new AbstractAction(){
public void actionPerformed(ActionEvent e){
keysPressed1[0] = true;
[Code] .....
This is mostly how reacting to key-presses and key-releases works in my program. When a key is pressed or released, a flag is set. The Board class reades the flags every game-loop cycle and reacts accordingly.
As I said, the program doesn't react correctly to more than 3 keys held at a time, probably because of the keyboard. Is there a way to code a solution?
