Answer:

Step 1

Step 2

Code:

 

import java.io.*;

import java.util.*;

public class Sample {

  //file handeling class to read and write text file

  public static class FileHandling {

    public static final String bookPath = "Data\book.txt";

    public static final String authorPath = "Data\author.txt";

    //function to write text file with given data

    public static void WriteFile(String data, String path) {

      try {

        BufferedWriter fileObj = new BufferedWriter(new FileWriter(path, true));

        fileObj.write(data);

        fileObj.close();

      } catch (IOException e) {

        System.out.println("Error while writing file." + e);

      }

    }

    //function to read text file and return all the data

    public static String ReadFile(String path) {

      String output = "";

      try {

        BufferedReader fileObj = new BufferedReader(new FileReader(path));

        String mystring;

        while ((mystring = fileObj.readLine()) != null) {

          output += mystring;

          output += "\n";

        }

      } catch (IOException e) {

        System.out.println("Exception Occurred" + e);

      }

      return output;

    }

  }

  public static void main(String[] args) {

    for (int i = 1; i <= 5; i++) {

      FileHandling.WriteFile(

        "Hello this is sample data #" + i + "\n",

        "data.txt"

      );

    }

    System.out.println(

      "Reading Data From text file:\n" + FileHandling.ReadFile("data.txt")

    );

  }

}
