Stopwatch Program In Netbeans
Oct 18, 2014
This is a stopwatch program. Somehow, the run method in the displayUpdater does not get called. Overall, the program should have a start button and when the user clicks start, the button changes into a timer. My timer doesn't count here because the run method is not called.
import java.awt.event.ActionEvent;
import javax.swing.SwingUtilities;
public class StopWatchNew extends javax.swing.JFrame {
/**
* Creates new form StopWatchNew
*/
public StopWatchNew() {
initComponents();
[Code] ....

I am working on splitting a time for a stopwatch and printing it on console,
String splitTimesStr = "";
currentTime = System.currentTimeMillis();
long secsTaken = (currentTime - startTime) / 1000;
long split = secsTaken - startTime;
[Code] ...
it produces
Split time: 00:02
Split time: 00:05
Split time: 00:08
Split time: 00:09
when it should produce
Split time: 00:02
Split time: 00:03
Split time: 00:03
Split time: 00:01
its printing out the time on stopwatch rather than: time on stopwatch - old time, how would i code this?

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

I am trying to run my program through netbeans and I get a message:
...build-impl.xml:1048 the module has not been deployed.
see the server log for details.
The corresponding line in the xml document is:
<nbdeploy clientUrlPart="${client.urlPart}" debugmode="false" forceRedeploy="${forceRedeploy}"/>
And in the server log there is a long list of comments, the first which looks to be of significance to this issue is:
WARNING [http-apr-8080-exec-57] org.apache.catalina.deploy.NamingResourcesImpl.cle anUp Failed to retrieve JNDI naming context for container [StandardEngine[Catalina].StandardHost[localhost].StandardContext[/transBoard]] so no cleanup was performed for that container
javax.naming.NameNotFoundException: Name [comp/env] is not bound in this Context. Unable to find [comp].
There are others further down the list which might also be significant such as:
SEVERE [http-apr-8080-exec-59] org.apache.catalina.core.ContainerBase.addChildInt ernal ContainerBase.addChild: start:
org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext[/transBoard]]
The corresponding line of code for the first warning that I listed is for the DataSource object and I wrote it as follows:
dataSource = (DataSource)
ic.lookup("java:/comp/env/jdbc/trans_board");
I'm pretty sure the issue has something to do with connecting to the database since it ran fine before I added the database related code.

It has no errors in it, but when it runs, it just doesn't show any output at all. Here's my code.
Fuel Class:
public class FuelGauge {
// Setting the gallons and the total amount of gallons
private int gallons;
final static int TotalGallons=15;
public FuelGauge(){
gallons=0;
}
// Initiate the number of gallons
public FuelGauge(int gallons){
[Code] .....

I am trying to create a program in NetBeans GUI builder and I am having trouble creating the 2D array. Here is what I have come up with so far:
private void enterButtonActionPerformed(java.awt.event.ActionEvent evt) {
// TODO add your handling code here:
double time = 0;
try{
time = Double.parseDouble(timeText.getText());
[Code] ....
Right now it is printing what i need but I need to separate columns, not rows.

Currently the while near the end is not working in netbeans. It is saying illegal start of type. This whole section was working before when it was within the public static void method. I moved it to a separate class to try and clear up a, static variable problem. My question is can i fix it to keep it structured this way. Or do I have to put it back into the main method and try to work out the static variable problem a different way.
public class InventoryProgram {
double[] dvdprice; // defines variables
int[] dvdnum;
int[] dvdstock;
String[] dvdnames;
int count;
double total;

I'm working on a University project creating a simple game using Netbeans but I'm totally stuck. I've created a number of classes to perform various methods, such as throwing back formatted text but I can't get them to work from within a Swing GUI created in Netbeans.
The Main method simply creates an instance of another class called Game which then itself creates instances of a number of other classes (textEngine, timer) and also a Swing GUI Class. The GUI appears on screen ok and I've been able to get methods working inside the GUI such as changing pictures and text when clicking a button. But I CANT get the GUI class to recognise the instances of the other classes or access their methods. I've created an instance of the TextEngine class called tEng. So I type this code in the GUI class:
textField.setText(tEng.getPhrase(2));
getPhrase() returns a String based on the number passed in the argument. But Netbeans reports an error that tEng is not recognised as a symbol despit it being a member of the same package. Creating the instance of the class within the GUI class likewise fails:
TextEngine tEng = new TextEngine();
Again the class is not recognised.

find a way to make all my clases in one single tab and not like this: URL....
because at the end of the exam, we have to paste the whole code (as one) in a specified web page, which instantly shows us the result. We need the whole code to be in just one page (like back in C++).

I'm running Netbeans 8.0 and attempting to use Apache POI to read various .xlsx files.
Currently, I'm getting a java.io.FileNotFoundException.
I'm using a Mac. What is the correct way to list the file path for my files in Netbeans? Also, is it possible to add the files to my actual project and access them inside the project?

I'm trying to create a GUI interface in Netbeans that calculates a phone bill.
I created a GUI interface that input:
- Account Name.
- Account Number.
- Number of Minutes the phone was used. (with a textarea so the user input the minutes)
- 2 JRadioButtoms so the user can chose the regular or premium service.
- Amount Due (+10% taxes) (also with a textarea)
- Clear/Enter/Result/Done Buttoms
And I need to output:
- Account Name.
- Account Number.
- Number of Minutes.
- Taxes
- Total Amount Due.
I have a couple of math formulas I have to add them to output the above however I'm new to java so I don't know which code to use.
The math formulas are:
-Regular charges = 20 + ( No. Minutes - 50 ) * 0.20
-Premium charges = 50 + ( No. Minutes - 75 ) * 0.50
-Taxes = ( Regular charges + Premium charges ) * 0.10
-Amount Due = Regular charges + Premium charges + Taxes

When I click on "Clean and Build" NetBeans generates a .jar file and inside the folder "dist" it add a directory called "lib" with all the java libraries used to implement the program. I would like to achieve with this IDE an unique .jar file that includes everything you need such as Eclipse does by default. Is it possible?

I'm just a java beginner. I've spent a lot of time installing and configuring software. I'm using Netbeans 7.3 on Windows 7, 64 bit. Recently, I downloaded opencsv from sourceforge.
With no previous experience adding libraries, I read a blog post on adding the library. I think that I then:
Start a new project.
Right click on libraries
Add jar/folder
Gave the temporary path to the .jar file
After, I read the blog post again, and realized I'd missed it. This time I did:
Right click library, Add library, Create library
However, I kept getting a message that the same library already existed. If I do the first process above, I will find the same library.
However, I see no way in Netbeans to remove it. I've deleted the test projects. And started a new one. But the library now exists for all projects it seems.
I've grepped all the files under the Netbean directory, searching for "opencsv", but found nothing. The only things in the Windows registry were locations of files.
How can I delete this library permanently from Netbeans? Short of, uninstall, then reinstall? Is there a way to list all the libraries that Netbeans has?

I have dragged and dropped a jTextArea from netbeans palette onto my form. But when I right clicked for Event > action > actionPerformed for implementation, I realized such was not there, unlike the jTextField component. For example, I have tried this but it didn't work:
//{
Import java.swing.*;
JTextArea txa = new JTextArea();
txa.getText(jTextArea1);
txa.setText(jTextArea1);
txa.setTextWrap(true);
