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 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.
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:
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();
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 want to connect netbeans to netlogo. I have a class: NetLogoConnection I want to call the class when I click on OK btn in my GUI. The codes are as following:
XML Code: import org.nlogo.app.App; public class NetLogoConnection { public static void main(String[] argv) { App.main(argv); try { java.awt.EventQueue.invokeAndWait( new Runnable() { public void run() {
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 are having some trouble with our quiz that we made in NetBeans. The problem we have is that when we press play the question opens in a new window ( if we klick this button imgur: the simple image sharer this happens imgur: the simple image sharer but we want it to look like this imgur: the simple image sharer when we press the button). the code we are using for the button is imgur: the simple image sharer.
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.
package javaapplication3; public class JavaApplication3 { public class robot { int xlocation; int ylocation; String name; static int ccount = 0;

I want to know that how can i use break points in net beans 8. I'm able to put break point by clicking at the line but don't know how to use it..Actually i'm getting wrong output of my code and i want to know my line by line execution of the code so i can get better idea of where is my code going from one line to other. I have used break point in micro soft visual studio2010 and that was easy after puting break point run the project then f11 to get line by line execution...I want to know any method exist in java net beans (i'm doing GUI swing controls)...
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?
my IDE doesn't seem to recognize that my program is a Swing app.I get the following error message when I run the app: "jtabledemo.JTableDemo class wasn't found in JTableDemo project."It compiles successfully though.Here is the code verbatim:
ActionPerformed and ActionListener on Netbeans...If I create a ComboBox on Netbeans using GUI design, then I right click over the Combobox I can find Events - Action - ActionPerformed... but I can't find ActionListener...
Are ActionPerformed and ActionListener the same?
or...
where is ActionListener on GUI Netbeans? Do I need to manualy write the ActionListener part?
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:
I make a coding a subject system for my internship project, I use JComboBox to choose name of faculty. I want to call selected item of faculty from another class to choose subject under the selected faculty.
How can I call selected item from another class?
This is my coding for select faculty.
public class lectInterface(){ private void saveDataActionPerformed(java.awt.event.ActionEvent evt) { String staff_id=staffID.getText(); int staff_Id=Integer.parseInt(staff_id); String Name=staffName.getText();
[Code] ....
and below is coding for another class
try{ LectInterface lI = new LectInterface(); String host = "jdbc:derby://localhost:1527/STUDLECDB"; String uName = "studlecdb"; String uPass = "studlecdb"; Connection con = DriverManager.getConnection( host, uName, uPass );
I am trying to create an application in java with jframe form and i am also running certain code in for loop. Here is the trick. I want to stop the operation in the middle of for loop by click a button and start it again by click another button if we want.
My problem i can't do anything while the for loop is running.
I want to follow this tutorial on YouTube but I cant seem to find the JRE System Library on NetBeans? So I decided to just get Eclipse but when I unzip the download and click either .exe files(I only see two .exe files) it gives me this message:
"The Eclipse executable launcher was unable to locate it's companion shared library."
Which ultimately prevents me from using the software completely.
Create a Java Application in NetBeans with the following two classes.
1. A Java class College o Use the following data fields: College Name College City Number of Tracks Number of Students Number of Faculty Number of Staff o Implement an empty constructor o Implement a full constructor o Implement Setters and Getters (Mutators and Accessors) o Implement SetAll() method with all data members as parameters
2. Another Java class called CollegeDemo with the main() method: o In the main(): o Read the values of the fields of 3 colleges from a text file and for each create a College object. Filename: colleges.txt IT Dubai 7 200 50 20 ENG Abudhabi 4 400 60 20 SCIENCE Sharjah 3 300 40 20 First with empty constructor then uses setters. Second with full constructor (no need to use setters). Last one with empty constructor and SetAll() setter. o Display the average number of students for all the 3 colleges. o Change the value of ‘Number of Students’ in the SCIENCE College to 500, and display the average number of students again.
here my code :
public class Demo { private String name ; private String city; private String cname ;
Now I want to store the image displayed in the jlabel into the database(oracle).From the above code I dont know how to get the absolute path of the images.
I would like a small box to be able to enter a contacts information and I started with building it thru netbeans. Now I am thinking I should start from scratch so I understand everything. What should I do? I am having trouble making the buttons at the bottom work. All I would like to be able to do is setFrameVisible(false); but I can't seem to be able to do that without loosing the whole project not just the frame I am working on.
The buttons I am referencing are the Cancel & Accept
public class pa4GUI extends javax.swing.JFrame { String ph; String ln; String fn; String em; String or;
I am having issue with jmenu popup in netbeans. It only sometimes works. Sometimes I don't get a java popup at all. Sometimes my File and Edit options are completely missing. This is what my code looks like.
import javax.swing.*; public class menu { /** * @param args the command line arguments */ public static void main(String[] args) { // TODO code application logic here JFrame f = new JFrame(); f.setVisible(true);
