[More Java help?]

I mostly work in C# but here's my attempt working with what you posted.

 

public boolean operate_on_file(java.util.ArrayList<java.io.File> files,File current_dir)   {
        try{
            for (File file : files) {
                BufferedImage image = ImageIO.read(file);
                File output = new File(current_dir+"/"+file.getName());            
                ImageIO.write(image, "png", output);
            }
        }
        catch(Exception e){
            return false;
        }
        return true;
    }
}

[[Suggestion] OPFOR Players]

Me too, maybe something like reinforcements with a troop count after a spawn it would subtract from the count and eventually allow Blufor to take the AO.
