Currently on the "File Handling" part of my java journey and came across a tutorial which showed how to copy a file with a single line of code as an alternative to using the core java classes. This involved using classes from the Apache Commons site, but so far I have not had any success in using it properly outside of Eclipse, which I'm staying away from for the time being (I'm using Notepad++).
I'm wanting to add the "Commons IO" library, but I'm guessing there's more to it than simply pasting it the jre/lib or jer/lib/ext folder, because so far my program keeps throwing the same error at compile time. I searched, but couldn't really find anything. Thank you in advance for your help and time.
