Java - Serialization - Using Serializable read and write object data to file

CODE

import java.util.*; import java.io.*; public class Main { public static void main(String[] args) { try{ Student s1 = new Student("Pedro", 30); String fileName = "student.txt"; //write the object to the file ObjectOutputStream output = new ObjectOutputStream(new FileOutputStream(fileName)); output.writeObject(s1); output.flush(); output.close(); //read the data from the file and assign it to the object ObjectInputStream input = new ObjectInputStream(new FileInputStream(fileName)); Student s2 = (Student)input.readObject(); input.close(); //display the details System.out.println(s2.toString()); } catch(Exception e) { System.out.println(e); } } } class Student implements Serializable { public String Name; public int Age; public Student(String name, int age) { this.Name = name; this.Age = age; } @Override public String toString() { String result = "Name: " + Name + "\n"; result += "Age: " + Age; return result; } }
