How to create multiple text file names in a for loop in java?

Question

This program creates 10 files on my desktop. The issue I am having is with the file names. The first one created is called "SecretFile1". The second is "SecretFile12". The third is "SecretFile123". What changes should I make so that the file names are "SecretFile1", "SecretFile2", and "SecretFile3" respectively?

import java.io.*;

public class TextFiles {

    public static void main(String[] args) throws IOException {
        String doc = "SecretFile";
        int number = 0;
        for(i = 1; i <= 10;i++){

            number++;

            doc = doc + number;
            String name = "C:\\Users\\Soumil\\Desktop\\" + doc + ".txt";

            BufferedWriter bw = new BufferedWriter(new FileWriter("" + name + ""));
            bw.write("There's no secret.");
            bw.close();
       }
   }
}

It's import java.util.Scanner;. util not io. Voting to close as a trivial typographical error. — Hovercraft Full Of Eels

How can you even make that typo? Did you really type the import by hand? — Tunaki

@Tunaki, I guess they are just using a text editor rather than an IDE? — Gavin

Try to use this import for Scanner class not import java.io.Scanner;: java.util.Scanner — Abdelhak

@user3370908 That's a different error. Please, take your time to think this through, read your code again, read the documentation. — Tunaki

Use this code, it will work!

String doc = "SecretFile";
        String dump="";
           int number = 0;
           for(int i = 1; i <= 10;i++){

               number++;

               dump = doc + number;
               String name = "F:/src/" + dump + ".txt";

               BufferedWriter bw = new BufferedWriter(new FileWriter("" + name + ""));
               bw.write("There's no secret.");
               bw.close();
          }

For reading data from file, you can use this code

import java.io.BufferedReader;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.InputStreamReader;

public class TextFiles {

    public static void main(String[] args) throws FileNotFoundException {
        FileInputStream fis = new FileInputStream("F:/input.txt");
        InputStreamReader input = new InputStreamReader(fis);
        BufferedReader br = new BufferedReader(input);
        String data;
        String result = new String();

        try {
            while ((data = br.readLine()) != null) {
                result = result.concat(data + " ");
            }
        } catch (IOException e) {
            e.printStackTrace();
        }

        System.out.println(result);
    }
}

Very poor code-only answer without any explanation.

I am an optimistic man. I have just tried to give him some quell, nothing else. Senior Bosses are already make this question as silly. :) When I was writing the answer, I know all people will give me curse...@Tunaki

I have some words in my text.txt , but when I try to print n or h nothing comes out.

You would help him better by explaining what the code does, how it does it and what he needs to change and why.
