Hi Friend,

Try the following code:

import java.io.*;
import java.util.*;

 public class BookBank{
    public static void main(String[]args)throws Exception{
        File f=new File("C:/books.txt");
        BufferedWriter bw=new BufferedWriter(new FileWriter(f,true));
        Book b=new Book();
        Scanner input=new Scanner(System.in);
        System.out.println("Book ID: ");
        String id=input.nextLine();
        System.out.println("Title: ");
        String  title=input.nextLine();
        System.out.println("Author: ");
        String  author=input.nextLine();
        System.out.println("Price: ");
        double  price=input.nextDouble();
        bw.write(id+" "+title+" "+author+" "+Double.toString(price));
        bw.newLine();
        bw.close();
        BufferedReader br=new BufferedReader(new FileReader(f));
        String line="";
        ArrayList list = new ArrayList();
           while((line = br.readLine()) != null){
           list.add(line);
           }
           Iterator itr;
           for (itr = list.iterator(); itr.hasNext();) {
           String str = itr.next().toString();
           String[] splitSt = str.split(" ");
           String ide = "", tit = "",aut="",p="";
           for (int i = 0; i < splitSt.length; i++) {
           ide = splitSt[0];
           tit = splitSt[1];
           aut = splitSt[2];
           p = splitSt[3];
           }
           System.out.println(ide+"    "+tit+"     "+aut+"    "+p);
           }
    }   
}

Hope that it will be helpful for you.

Thanks
