### Question
Step1: Serialize object **without** ```private Integer age;```
```
public class Demo1 {
@Data
public static class Class1 {
private String name;
// private Integer age;
}
public static void main(String[] args) throws IOException {
Fury fury = Fury.builder()
.withLanguage(Language.JAVA)
.withRefTracking(true)
.requireClassRegistration(false)
.withCompatibleMode(CompatibleMode.SCHEMA_CONSISTENT)
.build();
File file = new File("test.dat");
Class1 obj1 = new Class1();
obj1.setName("Tom");
byte[] data1 = fury.serialize(obj1);
FileUtils.writeByteArrayToFile(file, data1);
}
}
```
Step2: Derialize object **with** ```private Integer age;```
```
public class Demo1 {
@Data
public static class Class1 {
private String name;
private Integer age;
}
public static void main(String[] args) throws IOException {
Fury fury = Fury.builder()
.withLanguage(Language.JAVA)
.withRefTracking(true)
.requireClassRegistration(false)
.withCompatibleMode(CompatibleMode.SCHEMA_CONSISTENT)
.build();
File file = new File("test.dat");
byte[] data2 = FileUtils.readFileToByteArray(file);
Class1 obj2 = (Class1) fury.deserialize(data2);
Objects.equals("Tom", obj2.name);
}
}
```
Throw exception:
```
