Checking For Directory Existance

Im using some code to list the contents of a directory as a string, and Im wanting to add in some fail safes.

How would I go about checking if the directory exists first of all? If it doesnt exist, I want to output a message saying it doesnt exist.

Similarly, if the directory is empty I want to ouput that too.

check the API docs for File. Everything you need is in there, it's only a few lines of code.

That's See the "exists" method.
