Serialing Unserializable Classes

• Some classes are not serializable
• Security? Anonymous classes? Programmer cluelessness?
• Example: Ellipse2D.Double
• How can we serialize Car?
  
• Suppress default serialization to avoid exception
• Mark with transient:
  private transient Ellipse2D frontTire;
• Supply private (!) methods
  private void writeObject(ObjectOutputStream out)
  private void readObject(ObjectInputStream in)
• In these methods
• • Call writeDefaultObject/readDefaultObject
  • Manually save other data
    
• Ch7/serial/Car.java
