Introduction

In Java, working with files and directories is rather common. We are also often interested in the contents of those files and directories.

Depending on the contents of the file, we might want to behave differently. We might be writing some data into a file and we first want to check if it already contains some information before overwriting it. Similarly, we might be wanting to delete a directory if it’s empty. The knowledge of whether it’s empty or not can, in such cases, be of vital importance.

In this tutorial, we’ll go over some examples of how to check if a file or directory is empty in Java.
