You’ll find two examples demonstrating how to check if a File or Directory exists at a given path in Java.

Check if a File/Directory exists using Java IO’s File.exists()

package com.example.java.programming.file;
import java.io.File;
/**
 * @author code.factory
 *
 */
public class CheckFileExists {
	public static void main(String args[]) {
		File file = new File("test.txt");
		if (file.exists()) {
			System.out.printf("File %s exists%n", file);
		} else {
			System.out.printf("File %s doesn't exist%n", file);
		}
	}
}

Output :

File test.txt exists

Check if a File/Directory exists using Java NIO’s Files.exists() or Files.notExists()

package com.example.java.programming.file;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
/**
 * @author code.factory
 *
 */
public class CheckFileExists {
	public static void main(String args[]) {
		Path filePath = Paths.get("test.txt");
		// Checking existence using Files.exists
		if (Files.exists(filePath)) {
			System.out.printf("File %s exists%n", filePath);
		} else {
			System.out.printf("File %s doesn't exist%n", filePath);
		}
		// Checking existence using Files.notExists
		if (Files.notExists(filePath)) {
			System.out.printf("File %s doesn't exist%n", filePath);
		} else {
			System.out.printf("File %s exists%n", filePath);
		}
	}
}

Output :

File test.txt exists
File test.txt exists
