Question

Create a student class object array of size four having attributes name, designation and salary. Let the student class have appropriate getter/setters methods for accessing these attributes. Initialize these attributes through the setter methods. Store this object into a file "OutObject.txt". Read the objects from the same file and display the attributes of object through getter methods where name is equal to “rajiv” (ignoring case) else display the following message “The required information is not found in file”.

Answer:

package com.w3epic.wiprotraining.assignment1;

import java.io.FileInputStream;

import java.io.FileOutputStream;

import java.io.IOException;

import java.io.ObjectInputStream;

import java.io.ObjectOutputStream;

import java.util.Scanner;

import com.w3epic.wiprotraining.assignment1.bean.Employee;

public class Assignment1 {

public static void main(String[] args) throws IOException, ClassNotFoundException {

 Scanner sc = new Scanner(System.in);

 Employee emp = new Employee();

 

 System.out.print("Enter name: ");

 emp.setName(sc.nextLine());

 System.out.print("Enter D.O.B.: ");

 emp.setDob(sc.nextLine());

 System.out.print("Enter department: ");

 emp.setDepartment(sc.nextLine());

 System.out.print("Enter designation: ");

 emp.setDesignation(sc.nextLine());

 System.out.print("Enter salary: ");

 emp.setSalary(sc.nextDouble());

 sc.nextLine();

 

 FileOutputStream fos = new FileOutputStream("OutObject.txt");

 ObjectOutputStream oos = new ObjectOutputStream(fos);

 oos.writeObject(emp);

 

 FileInputStream fis = new FileInputStream("OutObject.txt");

 ObjectInputStream ois = new ObjectInputStream(fis);

 Employee emp2 = (Employee) ois.readObject();

 

 System.out.println("Name: " + emp2.getName());

 System.out.println("D.O.B.: " + emp2.getDob());

 System.out.println("Department: " + emp2.getDepartment());

 System.out.println("Designation: " + emp2.getDesignation());

 System.out.println("Salary: " + emp2.getSalary());

 

 fos.close();

 oos.close();

 fis.close();

 ois.close();

 sc.close();

}

 

}
