Using A Timer In Java Quiz
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.
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;

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

Using Count Element Method To Count Occurrence Of Characters In Array
Jun 30, 2014I have an array with the following characters {'E', 'L','E','P','H','A','N','T','P','O'}
now, I need an array that will store the first array such that only the occurence occurs e.g {'E','L','P','H','A','N','T','O'} Notice that the characters 'E' and 'P' occur twice and as a result were not repeated the second time in the new array.
How would one go about this using the counting elements technique?
I tried this but not sure how to use the counting elements technique.
char [] arr = new char{'E', 'L','E','P','H','A','N','T','P','O'};
char[] bucket = new char[(arr[0] * arr.length)];
for (int i = 0; i < len; i++)
bucket[arr[i]]++;
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
How To Count 1st Duplicates Value In Array By Using Java
Apr 12, 2015I have taken array int[] a = {33,33,5,5,9,8,9,9};
In this array so many values are duplicates means 33 comes twice & 5 also comes twice & 9 comes three times. But I want to count the first value which is duplicate means 33 is first value which comes twice so answer would be 2.
I try:
public class FindFirstDuplicate {
public static void main(String[] args) {
int c=0;
int[] a = {33,33,5,5,9,8,9,9};
outerloop:
for(int i = 0; i < a.length; i++) {
[code]....
Output:
33
Count: 1

Efficient XML Parsing For Count Using Java Hashmap?
Aug 20, 2014I am kind of new to Java. I have a query.. look at it. Have an xml like
<ProductList>
<Product Quality='Good' color='Blue'>
<Details ItemID='1001'/>
</Product>
...
..
</ProductList>
The <Product> tags can run into hundreds or thousands. Quality can have values like Good, Bad, Damaged. Color can also have various values (Blue, Red ..)
ItemID can repeat or can be different. So I want group by ItemID->Color->Good count or BadCount and TotalCount as below.
I want to get a sum like
<ProductList>
<ProductType ItemID="1001">
<Product_Detail CountGood="1" CountBad="2" CountTotal="3" Type="Blue"/>
</ProductType>
...
...
</ProductList>
I think using Hashmaps (Hashmap1 for ItemID, Hashmap2 for color, Hashmap3 for quality) may do the work. But I have to parse the xml number of ItemID's multiply-by number of colors multiply by various colors times for this.
Any better algorithm is there in performance perspective using Java.

Serializing A Timer
Jan 5, 2014One 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?
Changing Format For Timer?
Mar 17, 2014im 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.

Timer Class Without ActionEvent
Jul 29, 2014I 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.
