3. Vector

A vector is only serializable if all the elements are also serializable. Or, you'll get a NotSerializableException thrown.

import java.util.Vector;

public class MainClass {
  public static void main (String args[]) throws Exception {
    Vector v = new Vector(Arrays.asList("a","b","c"));
    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    ObjectOutputStream oos = new ObjectOutputStream(baos);
    oos.writeObject(v);
    oos.close();

    ByteArrayInputStream bais = new ByteArrayInputStream(baos.toByteArray());
    ObjectInputStream ois = new ObjectInputStream(bais);
    Vector v2 = (Vector)ois.readObject();
    Enumeration e = v.elements();
    while (e.hasMoreElements()) {
      System.out.println(e.nextElement());
    }
  }
}
