Java: Converting a set to an array for String representation

From Sun's Java Tutorial, I would have thought this code would convert a set into an array.

import java.util.*;

public class Blagh {
    public static void main(String[] args) {
        Set<String> set = new HashSet<String>();
        set.add("a");
        set.add("b");
        set.add("c");
        String[] array = set.toArray(new String[0]);
        System.out.println(set);
        System.out.println(array);
    }
}

However, this gives

[a, c, b]
[Ljava.lang.String;@9b49e6

What have I misunderstood?
