Accessing additional source-folders in JAVA

Question

I'm just starting to learn how to work with a res folder in Java... res and src are both in the buildpath however when I try to use ResourceLoader from my programDriver in src, it isn't able to resolve into a type. How do you ''import'' from additional source folders?

This is the resource loader class, if at all relevant:

public class ResourceLoader {
private static ResourceLoader rl = new ResourceLoader();
public static Image getImage(String fileName)
{
    return Toolkit.getDefaultToolkit().getImage(rl.getClass().getResource("images/"+fileName));
}

}

I'll add it but I don't see how it will help, the code itself isn't the source of my problem as much as ignorance on how to import a Class from an additional src folder named "res" — Batman, Apr 11 '16 at 03:27
More relevant might be the `ProgramDriver` code, since it is what is not able to find the `ResourceLoader` class. Anyone who is inclined to help you can't copy/paste the (ideally [mcve]) into their own IDE to attempt to debug the issue. — AJNeufeld, Apr 11 '16 at 03:37
agreed, said code has been added, but the image is mostly for the file-structure of the project. I know *why* ResourceLoader can't be resolved into a type... it hasn't been imported. If it were in another package, ez, no problem, regular import statement... My problem is it's in another *source* folder (called "res") and I have no idea how to import it within this context. — Batman, Apr 11 '16 at 03:40
The image of the file structure is useful, yes. But with a short snippets of both a main program (`ProgramDriver`) attempting to access `ResourceLoader` and a short `ResourceLoader` class, someone attempting to help could copy-paste into their IDE, setup similarly thanks to the project image, could immediately start to diagnose the issue, which is there is no way to ask Eclipse to import a `class` from a `package` with no name. Without it, the helper has to spend a minute or three creating both classes. You got an answer an hour after asking the question; it might have been a few minutes. — AJNeufeld, Apr 11 '16 at 03:53

You cannot import classes from the "default" package. There is no import default.ResourceLoader statement. The use of the "default package" is discouraged for a reason; this is it (or one of them, anyway).

Move your ResourceLoader into it's own package, and then you can use an import statement in your ProgramDriver java file.

package resPkg;

public class ResourceLoader {
    // ...
}

package program;

import resPkg.ResourceLoader;

class ProgramDriver {
    // ...
}
