January 8, 2024 - First, we used listFiles() to get all the contents of the folder. Then we used DirectoryStream to lazy load the directory’s content. We also used the list() method introduced with Java 8.

April 28, 2025 - ... // Java program list all files ... an object for specific directory File directory = new File(directoryPath); // Using listFiles method we get all the files of a directory // return type of listFiles is array File[] files = ...

October 1, 2022 - Collect all filtered entries into a List. //The source directory String directory = "C:/temp"; // Reading only files in the directory try { List<File> files = Files.list(Paths.get(directory)) .map(Path::toFile) .filter(File::isFile) .collect(Collectors.toList()); files.forEach(System.out::println); } catch (IOException e) { e.printStackTrace(); } DirectoryStream is part of Java 7 and is used to iterate over the entries in a directory in for-each loop style.

February 5, 2019 - They are – Files.walk() and Files.list(). The main difference between these two methods is, Files.walk() recursively traverses the given directory and it’s sub-directories to get list of all the files and folders in the hierarchy.

June 10, 2018 - List All Files in Directory and SubdirectoriesFiles.walk Return a Stream that is lazily populated with Path by walking the file tree rooted at a given starting file. Files.list Method Return a lazily

September 12, 2023 - The following is an another example to display all the files in a directory. import java.io.File; public class ReadFiles { public static File folder = new File("C:\\Apache24\\htdocs"); static String temp = ""; public static void main(String[] args) { System.out.println("Reading files under the folder "+ folder.getAbsolutePath()); listFilesForFolder(folder); } public static void listFilesForFolder(final File folder) { for (final File fileEntry : folder.listFiles()) { if (fileEntry.isDirectory()) { listFilesForFolder(fileEntry); } else { if (fileEntry.isFile()) { temp = fileEntry.getName(); if ((temp.substring(temp.lastIndexOf('.') + 1, temp.length()).toLowerCase()).equals("txt"))System.out.println( "File = " + folder.getAbsolutePath()+ "\\" + fileEntry.getName()); } } } } } The above code sample will produce the following result.

August 21, 2022 - The Files.list() static method from NIO API provides the simplest way to list the names of all files and folders in a given directory: try (Stream<Path> paths = Files.list(Paths.get("~/java-runner"))) { // print all files and folders ...

September 12, 2019 - In Java 8 and later we can use the java.nio.file.Files class to populate a Stream and use that to go through files and directories, and at the same time recursively walk all subdirectories. Note that in this example we will be using Lambda Expressions: public class FilesWalk { public static void main(String[] args) { try (Stream<Path> walk = Files.walk(Paths.get("D:/Programming"))) { // We want to find only regular files List<String> result = walk.filter(Files::isRegularFile) .map(x -> x.toString()).collect(Collectors.toList()); result.forEach(System.out::println); } catch (IOException e) { e.printStackTrace(); } } }

December 25, 2018 - try (Stream<Path> walk = Files.walk(Paths.get("C:\\projects"))) { List<String> result = walk.map(x -> x.toString()) .filter(f -> f.endsWith(".java")).collect(Collectors.toList()); result.forEach(System.out::println); } catch (IOException e) { e.printStackTrace(); }

July 23, 2025 - For main directory files, we use foreach loop. ... // Recursive Java program to print all files // in a folder(and sub-folders) import java.io.File; public class GFG { static void RecursivePrint(File[] arr, int level) { // for-each loop for main directory files for (File f : arr) { // tabs for internal levels for (int i = 0; i < level; i++) System.out.print("\t"); if (f.isFile()) System.out.println(f.getName()); else if (f.isDirectory()) { System.out.println("[" + f.getName() + "]"); // recursion for sub-directories RecursivePrint(f.listFiles(), level + 1); } } } // Driver Method public static

import java.io.File; import java.util.Arrays; public class DirectoryTestMain { public static void main(String[] args) { // create a file that is really a directory File aDirectory = new File("C:/temp"); // get a listing of all files in the directory String[] filesInDir = aDirectory.list(); // sort the list of files (optional) // Arrays.sort(filesInDir); // have everything i need, just print it now for ( int i=0; i<filesInDir.length; i++ ) { System.out.println( "file: " + filesInDir[i] ); } } }

July 29, 2019 - import java.io.File; /** * * @author www.codejava.net * */ public class ListDirectoryRecurisve { public void listDirectory(String dirPath, int level) { File dir = new File(dirPath); File[] firstLevelFiles = dir.listFiles(); if (firstLevelFiles != null && firstLevelFiles.length > 0) { for (File aFile : firstLevelFiles) { for (int i = 0; i < level; i++) { System.out.print("\t"); } if (aFile.isDirectory()) { System.out.println("[" + aFile.getName() + "]"); listDirectory(aFile.getAbsolutePath(), level + 1); } else { System.out.println(aFile.getName()); } } } } public static void main(String[] args
