To check whether the file exists or not, we have to import io package. And from this package, we have to import File Class.

import java.io.File;

File f = new File(filePathString); //filepath will be the directory path where you want to search a file
if(f.exists() && !f.isDirectory()) {
    System.out.println("File exists");
}

Instead of using exists(), we can use isFile() because, will return true but will not allow you to open and read from it as a file.

new File("path/to/file.txt").isFile();

Using nio we can check whether file exists or not.

import java.nio.file.*;

Path path = Paths.get(filePathString);

if (Files.exists(path)) {
  // file exist
}

if (Files.notExists(path)) {
  // file is not exist
}
