Hi,

Following example code reads the data from data.txt file and then prints on the console:

package my.code;

import java.io.File;
import java.io.FileNotFoundException;
import java.util.Scanner;

public class ScannerReadFile {

    public static void main(String[] args) throws FileNotFoundException {
        // File to read
        String fileName = "data.txt";
        // Read file with Scanner class
        try (Scanner scanner = new Scanner(new File(fileName))) {
            // Print all data
            while (scanner.hasNext()) {
                String line = scanner.nextLine();
                System.out.println(line);
            }
        }

    }

}

Thanks
