Practical 11 : Create a class called Student. Write a student manager program to manipulate the student information from files by using FileInputStream and FileOutputStream

Program :

import java.io.FileInputStream;

import java.io.FileOutputStream;

public class practical11 {

    public static void main(String[] args) {

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

        try {

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

            String str = "Nmae : Pruthviraj, Stream : INFORMATION TECHNOLOGY, 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("-------Retrive Data From File-------");

        try {

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

            int i = 0;

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

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

            }

            fin.close();

        } catch (Exception e) {

            System.out.println(e);

        }

    }

}
