Hello all,
I have the bluej source code in eclipse, and it compiles fine, but when I try to run it BlueJ starts fine, and then pops up an error window that says that bluej couldn't create a VM.
...

thanks for the suggestion, I actually already have the bluej source, but I haven't been able to run it out of Eclipse, I get a very strange error, but I will definitely look in those packages now....

What exactly is your question?

I didn't run into any problems with your code, I added the necessary imports to run it, and commented out the five lines of code that deal with classes that you did not include:

We can only help if we can see the code, otherwise there is no way for us to know what is wrong, it could be something simple your overlooking.

Hello all,
As you may know by now, from my previous posts recently, I am working on a Paint application. My question, then, surprisingly does not involve Graphics or Swing.

So my question...

Thanks for the reply, I will look into that, it probably would be more efficient that way.

Well, as an update, I'm using this as a temporary solution,

I didn't want to post my code before because it's long and dididn't have any comments, now that I've commented it I suppose I'll post it. I have the JList displaying exactly what I wanted to,...

Hello All, it's been a while since I've had a question for you all.
I'm trying to write a paint app, I've done so before, but this time I decided to add Layers, and I wanted a JList of the layers, I...

I think I can shed some light on why people have stopped replying... People don't like that sort of application, so not many people are willing to help create one.

if I were to give a fast guess,...

Thanks, perhaps I'll just make it for only one type. The reason I wanted this is because I wanted to have a position in an array as a vector which has to be an int, but I also wanted to be able to...

Look at the java tutorial on collections there is an entire trail there, here is a link: Collections trail (http://java.sun.com/docs/books/tutorial/collections/index.html)

What do you mean by "fake Java"? Do you mean Processing (http://processing.org/reference/environment/)? if that is the case than you can simply download it as it is free.

If it is not processing,...

what i mean by "cannot do that" is that because of the generic within the class trying to take the component x of type <T> and add it to another Java won't accept that as correct.
here is the code...

Hello all, it's been a while since I've had a question, but I'm back.

I'm trying to write a Vector class which can be any type. The problem I have is that generics can only hold objects, so when I...

Thanks for the information, I didn't realize that there were more posts here, because I didn't get the normal e-mail from daniweb. thanks i'll use that Ezzaral.

thanks for the reply (and welcome to daniweb first post I see) I ended up doing that already, I figured it could be a temporary solution, until someone here might come up with something else, maybe...

I have a new suggestion for you.

Make a new JPanel, or JComponent instance in your constructor, then rather than adding your listeners to this add them to the JPanel/JComponent and add the...

unable to edit last post, sorry about the double post and the bump, but I thought about something else that I could use some advice on.

Hello, this is related to the last thread I posted (http://www.daniweb.com/forums/thread177461.html), but it is also different. I found something about ImageObserver with a google search and can't...

I'm not sure, usually the component in question has to have focus. The only way I have been able to get a key listener to work is to derive from JComponent rather than JFrame then add the derived...

Hello,
I think I may have found a reason, but I also have a few questions, the first of which is why are you using a window listener, the same action could be done with:...

So, I got this idea that I could make a simple game in Java, with animated GIFs for the running animations, but I have a problem, although Java will display the animation on a JLabel when made into...

I know, but, i've tested out some random stuff, and my way makes a better spread.

may i suggest that you look at the first thread i started after my joining Daniweb? it has a solution to the problem that i got from a book (the art of java, search it on amazon), but i do suggest...

The Art Of Java (http://www.amazon.com/Art-Java-One-Off/dp/0072229713) has an example of a web crawler, but it doesn't go into mySQL.
