Im having an error here and I dont know why. My code is exactly the same as Craig Dennis.

package com.teamtreehouse;

import java.io.*;

public class Treets {
  public static void save(Treet[] treets) {
    try (
      FileOutputStream fos = new FileOutputStream("treets.ser");
      ObjectOutputStream oos = new ObjectOutputStream(fos);
    ) {
      oos.writeObject(treets);
    } catch(IOException ioe) {
      System.out.println("Problem saving Treets");
      ioe.printStackTrace();
    }
  } 
}

And this is the error i get

java.io.NotSerializableException: com.teamtreehouse.Treet                              
        at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1184)       
        at java.io.ObjectOutputStream.writeArray(ObjectOutputStream.java:1378)         
        at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1174)       
        at java.io.ObjectOutputStream.writeObject(ObjectOutputStream.java:348)         
        at com.teamtreehouse.Treets.save(Treets.java:11)                               
        at Example.main(Example.java:21)

Hmmm that error is saying your Treet class doesn't implement Serializable. Does it?
