1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 | package com.karlsangabriel.io; import java.io.File; public class FileOrDirectoryExample { public static void main(String[] args) { File aFile = new File("C:/somewhere/FileOrDirectoryExampleTestData/file.txt"); File aDirectory = new File("C:/somewhere/FileOrDirectoryExampleTestData/directory"); System.out.println("aFile is a file? " + aFile.isFile()); System.out.println("aDirectory is a direcory? " + aDirectory.isDirectory()); } } |
This outputs
