Currently I am trying to save and load a number of objects from a vector, however I have had no luck due to a java.lang.ClassCastException error.
I have been puzzed by this error for hours now, and have tried many methods without success.

Code:

import javax.swing.*;
import javax.swing.event.*;
import java.awt.*;
import java.awt.event.*;
import java.util.*;  
import java.io.*;

class testing extends JFrame implements ActionListener
{
	Container c2;

	JButton addbutton;
	JButton savebutton;
	JButton openbutton;
	
	String name;
	String age;
	
	Vector vector;

	public static void main (String args[]){new testing();}
	
	public testing()
	{
		vector = new Vector();
		name = "Name";
		age = "Age";
		makeButtons();
		setSize(200, 150);
		setVisible(true);
	}

	public void makeButtons()
	{
		c2 = getContentPane();
		c2.setLayout(new FlowLayout());
		
		addbutton = new JButton("Add");
		c2.add(addbutton);
		addbutton.addActionListener(this);
		
		savebutton = new JButton("Save");
		c2.add(savebutton);
		savebutton.addActionListener(this);
		
		openbutton = new JButton("Open");
		c2.add(openbutton);
		openbutton.addActionListener(this);		
	}
	
	public void actionPerformed(ActionEvent eh)
	{		
		String action = eh.getActionCommand();

		if(action.equals("Add"))
		{
			Vector r = new Vector();
			r = createElement();
			vector.addElement(r);
		}
		
		else if(action.equals("Save"))
		{
			try
			{
				System.out.println("Writing Object");
				ObjectOutputStream out = new ObjectOutputStream(new FileOutputStream("test.tmp"));
				for(int i=0; i<vector.size(); i++)
				{
					Person temp = (Person) vector.elementAt(i);
					out.writeObject(temp);
				}
				
				out.close();
			}
			catch(Exception e){e.printStackTrace();}
		}
		
		else if(action.equals("Open"))
		{
			try
			{
				System.out.println("Reading Object");
				ObjectInputStream in = new ObjectInputStream(new FileInputStream("test.tmp")); 
			
				while(true)
				{
					Person temp = (Person) in.readObject();
					vector.addElement(temp);
				}
			}
			catch(Exception e ){e.printStackTrace();}
		}
		
		System.out.println(vector);
	}
	
	public Vector createElement() 
	{
		Vector t = new Vector();
		Person p = new Person(name, age);
		t.addElement(p.name);
		t.addElement(p.age);
		return t;
	}
				
	class Person implements Serializable 
	{
		String name;
		String age;
		
		public Person(String name, String age)
		{
			this.name = name;
			this.age = age;
		}
	}
}
