In programming, it’s often necessary to check if a directory exists before performing certain operations. In Java, there are several ways to accomplish this task. One common approach is to use the `Files.exists()` method, which takes a `Path` object representing the directory in question. If the directory exists, the method returns `true`; otherwise, it returns `false`.
Another option is to use the `isDirectory()` method, which is part of the `File` class. This method also takes a `Path` object as input, but it returns `true` if the specified path represents a directory and `false` if it represents a file or does not exist.
