Only object that implements Serializable interface can be saved and restored by the serialization facilities.
Serializable interface defines no operations.
Why? Because the Serializable interface only indicates that a class may be serialized.
import java.util.*; import java.io.*; class Person implements Serializable{ private String name; public Person() { } public Person( String n ){ System.out.println("In Person ctr"); name = n; } String getName() { return name; } }
