Two quick (and simple) questions

[Astralogic]

Hello, how do I import a class into a project? I know I could just re-create the empty class and paste the code into it, but I've already done that and I think it's time to learn how to do it properly :)

Also, if I want to refer to an image file without any sort of path to it, where do I put the image file? In other words I'd like to refer to it by filename alone.

Thanks

Where is the class you want to import located?
Look into how API's and class libraries are built and how you import them.

Where are you going to include the path to the image you want to use (where in the code)?

Please go through the Forum Rules -- particularly the third paragraph.

Where is the class you want to import located?

Workspace\ImageLoader\ImageLoader.java <- that's the class I want to import.

Where are you going to include the path to the image you want to use (where in the code)?

It will be in the ImageLoader class. I have a loadImageFromFile(String) method and a loadImageFromInternet(String) method. I want to call the loadImageFromFile() method and send it just the filename of the image rather than the whole path.

How do I make my project refer to another project? "import Imageloader.ImageLoader;" does not work.

Does anyone know of a more active Java forum?

extends or implement

I've used the extends keyword several times to extend Frame and Canvas objects. I don't know how to use "implement" if that's a keyword.

This just MAY be too complex for me to do at this level, I just though it would have been quite a simple thing to do.

But extending a class or implementing an interface is not how you import a class.

What do you mean by "does not work"? Do you receive any errors? If so, please post the full error messages.

Is ImageLoader.java inside a package called ImageLoader? Do you include the directory where the ImageLoader package is located within your classpath when compiling the class that utilizes ImageLoader?

I thought I replied to you ages ago, good job I came back to this thread. I have solved my first problem, I didn't add the project to the classpath, doing so solved it.

But could someone tell me where I should put an image file if I want the below method to work if the "filename" String variable passed into it is just a filename with no path.

public Image loadImageFromFile(String filename) {
		Image image = null;
		Toolkit tk = Toolkit.getDefaultToolkit();
		image = tk.getImage(filename);
		waitForImage(image);
		return(image);
	}

Thanks, I'm now learning how to use Swing.
