Using Externalization and Evolution

Running the Example

Complete the following procedure to compile and run this example:

From yourbasedir/objectserializationexamples/ExternalizationandEvolution, compile the Original Class using JDK™ 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).
