Message: [QUOTE="Lasse Reichstein Nielsen, post: 3577810"] Correct. It's a "marker interface" which merely marks the class as being intended for serialization. The serialization code checks for the marker, and refuses to serialize something without it - not because it couldn't, but just because it won't - serializing and derserializing something not build for it could cause unexpected trouble. Today it would probably have been implemented as an inherited annotation. If it implements the Serializable interface. Yes, that class isn't serializable. No need to write the "extends Object". The class will automatically extend Object if no other superclass is given. That it implements the interface! That means that the default serialization code will accept to serialize and deserialize objects of that class. /L [/QUOTE]
