Question

Create an employee object having properties name, date of birth, department, designation and salary. Let the employee class have appropriate getter/setters methods for accessing these properties. Initialize these properties through the setter methods. Store this object into a file "OutObject.txt". Read the same object from the same file and display its properties through getter methods.

import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
import java.io.IOException;


public class Main
{
	public static void main(String[] args) {
		Employee e = new Employee();
		e.setName("Anne");
		e.setDateOfBirth("12/09/1999");
		e.setDepartment("Computer Science");
		e.setDesignation("Lecturer");
		e.setSalary(20000);
		
		FileOutputStream f1 = new FileOutputStream("OutObject.txt");
		ObjectOutputStream f2 = new ObjectOutputStream(f1);
		f2.writeObject(e);
		FileInputStream f3 = new FileInputStream("OutObject.txt");
		ObjectInputStream f4 = new ObjectInputStream(f3);
		Employee e2 = (Employee) f4.readObject();
		System.out.println("Name: " + e2.getName());
		System.out.println("Date of Birth: " + e2.getDateOfBirth());
		System.out.println("Department: " + e2.getDepartment());
		System.out.println("Designation: " + e2.getDesignation());
		System.out.println("Salary: " + e2.getSalary());
		f1.close();
		f2.close();
		f3.close();
		f4.close();
