ObjectInputStream和ObjectOutputStream。

public class SerializationDemo {

public static void main(String[] args) {
// TODO Auto-generated method stub
try {
Vector list;

BufferedReader reader = new BufferedReader(new InputStreamReader(
System.in));
System.out.print("Checking for previous serialized list");

try {
FileInputStream fin = new FileInputStream("list.out");

ObjectInputStream oin = new ObjectInputStream(fin);

try {
Object obj = oin.readObject();
list = (Vector) obj;

} catch (ClassCastException e) {
// TODO: handle exception
list = new Vector();
} catch (ClassNotFoundException e){
list = new Vector();
}
fin.close();

} catch (FileNotFoundException e) {
// TODO: handle exception
list = new Vector();
}

for (;;){
System.out.println("Menu :-");
System.out.println("1.. Add item");
System.out.println("2.. Delete item");
System.out.println("3.. List items");
System.out.println("4.. Save and quit");
System.out.println("Choice");

String response = reader.readLine();
int choice = Integer.parseInt(response);

switch (choice) {
case 1:
System.out.print("Enter item : ");
String item = reader.readLine();
list.addElement(item);
