How to read a file using scanner type Scanner?

Question

I have a file and I am extracting some data from it using key one by one.After a successful match, I want to reset the scanner object to start from the first line of the file again.

Answer 1

Use following codes to read the file
import java.io.File;
import java.util.Scanner;

 public class ReadFile {
    public static void main(String[] args) {
     File file = new File("input.txt");
     try {
        Scanner sc = new Scanner(file);
        while (sc.hasNextLine()) {
            int i = sc.nextInt();
            System.out.println(i);
         }
        sc.close();
      } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (Exception ex) {
        ex.printStackTrace();
    }
}

}
