import java.io.FileInputStream;
import java.io.ObjectInputStream;
import java.io.Serializable;
public class Main {
public static void main(String[] args) throws Exception {
ObjectInputStream inputStream = new ObjectInputStream(new FileInputStream("yourFile.dat"));
Object obj = null;
while ((obj = inputStream.readObject()) != null) {
if (obj instanceof Person) {
System.out.println(((Person) obj).toString());
}
}
inputStream.close();
}
}
class Person implements Serializable {
private String firstName;
private String lastName;
private int age;
public Person() {
}
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public String toString() {
StringBuffer buffer = new StringBuffer();
buffer.append(firstName);
buffer.append("\n");
buffer.append(lastName);
buffer.append("\n");

buffer.append("\n");
return buffer.toString();
}
