Serialization, Evolution, and the Addition of a New SuperClass
Running the Example
Complete the following procedure to compile and run this example:
- From yourbasedir/objectserializationexamples/AddingNewSuperClassAndEvolution, compile the Original Class using JDK™ 1.2 or higher:
javac OriginalClass.java
- Run the Original Class with the serialization flag:
java OriginalClass -s
- Compile the Evolved Class:
javac EvolvedClass.java
- Run the Evolved Class with the deserialization flag:
java EvolvedClass -d
This procedure tests compatibility in one direction only. To test bidirectional compatibility, perform the same procedure in the other direction (in steps 1-4, replace the original class name with the evolved class name, and vice versa).
