Practical 11

Aim:- Create a class called Student. Write a student manager program to manipulate the student information from files by using FileInputStream and FileOutputStream.

JAVA Code :-

import java.lang.*;

import java.io.*;

public class pra11

{

    public static void main(String[] args)

    {

        System.out.println("\n-------Writing Data in File-------");

            try {

                   FileOutputStream fout = new FileOutputStream("a.txt");

                  String str = "Nmae : Ayush, Stream : IT Engineering, Sem : 5th Sem";

                  byte b[] = str.getBytes();

                  fout.write(b);

                  fout.close();

                  System.out.println("successful write.");

           }  

            catch (Exception e) {

                  System.out.println(e);

             }

            System.out.println("\n-------Retrive Data From File-------");

            try {

            FileInputStream fin = new FileInputStream("a.txt");

            int i = 0;

            while ((i = fin.read()) != -1) {

                System.out.print((char) i);

            }

            fin.close();

        }

            catch (Exception e) {

            System.out.println(e);

        }

    }

} 

Output:-
