Java 8+ version:
import java.nio.file.Paths;
import java.nio.file.Files;
Files.createDirectories(Paths.get("/Your/Path/Here"));
The Files.createDirectories() creates a new directory and parent directories that do not exist. This method does not throw an exception if the directory already exists.

January 27, 2024 - Then we can pass that Path to the Files.exists(Path) method: Path path = Paths.get("does-not-exist.txt"); assertFalse(Files.exists(path)); Since the file doesn’t exist, it returns false.

Using java.nio.file.Files:
Path path = ...;
if (Files.exists(path)) {
// ...
}
You can optionally pass this method LinkOption values:
if (Files.exists(path, LinkOption.NOFOLLOW_LINKS)) {
There's also a method notExists:
if (Files.notExists(path)) {

Quite simple:
new File("/Path/To/File/or/Directory").exists();
And if you want to be certain it is a directory:
File f = new File("/Path/To/File/or/Directory");
if (f.exists() && f.isDirectory()) {
...
}

April 2, 2019 - If you create a File object for the directory you want to create you can use the isDirectory() and exists() methods to determine if a directory (or file) with that name already exists and if it doesn't use the mkDir() or mkDirs() method to create the directory.

April 13, 2022 - Once the folder has been created, we are going to use ‘exists‘ and ‘isDirectory’ method of Java-IO library. They will test whether the folder is present or not and if it’s a directory or not, based on the output, it will throw ‘pass‘ or ‘fail‘ in return. ... Now, by using below line of code, we are deleting the created folder and performing the folder existence check again.

Checking a File or Directory (The Java™ Tutorials > Essential Java Classes > Basic I/O)
The file is verified to not exist. The file's status is unknown. This result can occur when the program does not have access to the file. If both exists and notExists return false, the existence of the file cannot be verified.

!Files.exists() returns:
trueif the file does not exist or its existence cannot be determinedfalseif the file exists
Files.notExists() returns:
trueif the file does not existfalseif the file exists or its existence cannot be determined

As we see from Files.exists the return result is:
TRUE if the file exists;
FALSE if the file does not exist or its existence cannot be determined.
And from Files.notExists the return result is:
TRUE if the file does not exist;
FALSE if the file exists or its existence cannot be determined
So if !Files.exists(path) return TRUE means it not exists or the existence cannot be determined (2 possibilities) and for Files.notExists(path) return TRUE means it not exists (just 1 possibility).
The conclusion !Files.exists(path) != Files.notExists(path) or 2 possibilities not equals to 1 possibility (see the explanation above about the possibilities).

String fileName = "/home/janbodnar/tmp/newdir"; Path path = Paths.get(fileName); A Path is created from the file name. A Path is a Java object used to locate a file in a file system. if (!Files.exists(path)) { We first check if the directory does not already exist with Files.exists.
