Complete the following procedure to compile and run this example:
- From yourbasedir/objectserializationexamples/ExternalizationandEvolution, compile the Original Class using JDKTM 1.2 or higher:javac ExternExampleOriginalClass.java
- Run the Original Class with the serialization flag:java ExternExampleOriginalClass -s
- Compile the Evolved Class:javac ExternExampleEvolvedClass.java
- Run the Evolved Class with the deserialization flag:java ExternExampleEvolvedClass -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).
