import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.ObjectInputStream;
import java.util.List;

public class ObjectInputStreamTest {

  /**
   @param args
   */
  public static void main(String[] args) {

    try {
      List<String> list = null;
      
      ObjectInputStream input = 
        new ObjectInputStream(new FileInputStream("C:\\example.ser"));
      
      list = (List<String>input.readObject();
      input.close();
      
      System.out.println("list : " + list);
      
    catch (FileNotFoundException e) {
      e.printStackTrace();
    catch (IOException e) {
      e.printStackTrace();
    catch (ClassNotFoundException e) {
      e.printStackTrace();
