Looping through serialized objects?

Question

I have made a program which stores the game score such as seen 3d pinball. I know how to store then but I don't know how to loop through all records so that I can store them in one single array so that I can perform diffenent operations on that array.
such I should arrange them and find out the top five scorer. Give me some valueable hints.

Demo:
import java.io.*;
import java.util.*;
public class Example implements Serializable {
    private static final long serialVersionUID = 1;
    private String text;
    public Example(String text) {
        this.text = text;
    public String toString() {
        return text;
    public static void main(String[] args) throws IOException, ClassNotFoundException {
        List<Example> list = new ArrayList<Example>();
        Collections.addAll(list, new Example("hello"), new Example("world"));
        File file = new File("temp.dat");
        ObjectOutputStream out = new ObjectOutputStream(new FileOutputStream(file));
        out.writeObject(list);
        out.flush();
        out.close();
        ObjectInputStream in = new ObjectInputStream(new FileInputStream(file));
        List<Example> input = (List<Example>) in.readObject();
        in.close();
        System.out.println(input);
}
