End Is Not Working In Netbeans

Jun 2, 2014

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;

Other Classes Not Recognised By NetBeans GUI

Jan 21, 2014

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.

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.

Netbeans - Calculation In GUI Interface

May 12, 2014

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

Netbeans - How To Remove Added Library

Feb 13, 2014

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?

txa.setText(jTextArea1);
