I thought when Java classes are in the same directory, you don't need to import another class when you use it inside another. I have this class that will initiate Cloudinary uploading of files back to the cloud, but when I call it inside another class and run build I get this error 'cannot access CloudinaryUpload'

The Cloudinary class

import java.io.IOException;
import java.util.HashMap;
import java.util.Map;

import com.cloudinary.Cloudinary;
import com.cloudinary.utils.ObjectUtils;

public class CloudinaryUpload {

    public static void main(String arg[])throws Exception{
        Map config = ObjectUtils.asMap(
            "cloud_name", "name",
            "api_key", "api_key",
            "api_secret", "api_secret",
            "secure", true
        );
        Cloudinary cloudinary = new Cloudinary(config);
    }
}

Just a snippet of code of another class where I am calling it

public class ClientManagerServices {

    private static final int BYTES_DOWNLOAD = 1024;
    
    //The Cloudinary class
    private CloudinaryUpload cloudinaryUpload = CloudinaryUpload();
    public static String getMessageBody(Delegator delegator, String requester, String subject, String registryFileId, String clientId) {

        GenericValue fileData = null;
        GenericValue userData = null;
        GenericValue clientData = null;
        String bodyToReturn = "";

        try {
            fileData = delegator.findOne("RegistryFile", UtilMisc.toMap("registryFileId", registryFileId), false);
        } catch (GenericEntityException e) {
            e.printStackTrace();
        }
}

This line:

private CloudinaryUpload cloudinaryUpload = CloudinaryUpload();

If that is supposed to creating new instance it should be

private CloudinaryUpload cloudinaryUpload = new CloudinaryUpload();

Note ... new. If you leave out the new, then that is a call to a method named CloudinaryUpload ... and no such method exists in your code.
