Excellent, thank you very much!

Hi guys,

I am using boolean variables as flags in a program and i want to be able to invert the value.

for example if the current value is true, then it must be changed to false; doesn't matter...

Thanks very much poeticinsanity. I wasn't sure if it would work, but it does. Thank you.

Hi guys,

I want to paint multiple layers of images onto one image. I'm going to be using BufferedImage for this.

How would I go about painting these multiple images onto one (in essence...

so i should use multiple glass panes and then paint the various layers to a specific glasspane?

Hey guys

I'm using JLayeredPane because i want three distinct layers in my program. terrain, buildings and then characters.

I thought that JLayeredPane was easily the best choice for this...

Hi guys

I want to take an image and cut it into blocks, then store each block in an array of bufferedimages.

I have tried many things

public void splitImage(int cols, int rows)
{

Hi, i'm making a class which runs on a different thread to the main class. I want this thread class to listen for keyboard events and then I will have specific action from there.

The thing is, I...

Ta DAHH! I get 500 every time. Thanks a lot, I was leaving room for error in my original code, but when it returned differences below what i was sleeping the thread for, i got worried.

Thanks a...

I threw together a quick program to test if sleep works



and the difference between the 2 values was either 16 or 31 (give or take one or two milliseconds) and as far as I'm concerned this...

Oh, my bad. It was more of an example.

But basically, can you make a thread sleep even if you haven't declared a Thread anywhere.

For example Thread.sleep(20);

I was wondering do all programs have a unnamed thread by default?

For example, if i have a very basic program, can i put Thread.sleep(int) anywhere in it and it will make the program sleep for a...

Hi

I am having problems with BufferedImage. What i would like to do is create a bufferedimage from an image stored on the hard disk. For example, i create a new file pointing to this image file....

If nobody is replying because I haven't tried, i have. I just don't have any idea how to do it

Hi, I just wanted to ask for some help considering images.

What I would like to do is take an image and then split it up into blocks of a certain dimension (say, 20x20). Then I would like to put...

Ok cool, thanks very much.

Well firstly, does the method I listed work?

Thanks,

Another question about arrays is whether I can take all the values from one array and put them in another one. In the same order obviously.

So can I say


Is there another way to do...

Thanks alot, 5 is the max number anyway, thats why I chose it originally.

Thanks very much

Ok, i've managed to get it working by referencing it with globalVariable.variable_in_question

For some reason i had to set the variables in globalVariables to static. Anyone care to explain this?

I create an object of the type globalVariables, this has the variables needed in it.

When I create the object in one of my methods (in another class) i get an error saying that it can't find the...

Yeah, thanks.

I have already started doing this. I just thought that there was perhaps a keyword or statement for this or something.

Thanks for the help!

Thanks, will read through that. Another problem, which i have checked the internet for, is a global variable.

I have a couple of class files which are their own JFrames; I have a variable called...

Hi

I'd like to use an array to store values of particular things. I would like names to correspond to each value in the array. What I was thinking was, should I perhaps create 2 arrays: String[]...

I collect my data from JTextFields.

Im using a JFrame.

LOL nice,

I thought you were going to ask wtf I was talking about.

:)

I'l rather cut my losses on the incrementing value field thing.

But, what I need to ask is how I would go about creating something dynamic.

I have 3 text fields, I want the values you put into...

Oh.....

Hmm, how should I go about that?
So there is no java equivalent?

Maybe?

No, it isn't that. its one of those things where there are numbers and pressing the arrow up on the side, increases the value by one inside.

well, im not sure, but your code says

and you declared income as a double.

And provincial also relies on income for its value, so thats why it doesn't work.

Hi again

What is the name of the component in programs where there is:

a 2 character text field and on the side there are up and down arrows to increase or decrease the value in the text field....

Ok, thanks very much.

And thanks for helping with my petty questions.

Thread solved.

Thanks so very much, I keep on making these stupid errors.

Just on the side, is there any way to edit the title of the showMessageDialog? and possibly the icon?

Thanks again.

EDIT: Are the...

Hi guys

I can't seem to get a new line in a JOptionPane.showMessageDialog(null, " "); statement. I try the /n command, but it still doesn't seem to work.

Is there any way I can get a paragraph...

Thanks very much man, I never would have found such an annoying error.

Thanks!

Hi guys

I am trying to build a program which scans data from a text file, but I keep getting an error when trying to compile it.

The code

import javax.swing.*;
import java.awt.*;
import...

Well, add a method in the program which runs a batch file which can then compile for you.

nobody is going to do this for you, don't demand us to do the project.

The else provides a fallback condition. Just a single if is there for one condition only.

for example, if you put just an if in the code, it goes through one condition then continues with the...

Hi, do any of you know any good resources for (2d) game development in java? I want to build a game but need a good tutorial/resource for such a thing. Can you help?
