Read Text File in Java using Scanner Class

 Previously I have posted about reading text file using FileInputStream and BufferedReader. This post shows how to read text files in java using the Scanner class.


This is a sample text file


and this is the java code to read text files using the Scanner class

  1. package client;
  2. import java.io.File;
  3. import java.io.FileNotFoundException;
  4. import java.util.Scanner;
  5. public class ReadFileScn {
  6. public ReadFileScn() {
  7. super();
  8. }
  9. public static void main(String[] args) {
  10. // Absolute path of file that you want to read
  11. File f = new File("D:/sampleFile.txt");
  12. Scanner s = null;
  13. try {
  14. s = new Scanner(f);
  15. } catch (FileNotFoundException e) {
  16. }
  17. //Iterate over file content
  18. while (s.hasNextLine())
  19. System.out.println(s.nextLine());
  20. }
  21. }

Execute this java code

Output is


Cheers 🙂 Happy Learning
