Java关键字—-transient

写一段代码理清序列化、反序列化的流程。本篇文章序列化、反序列化用的类是同一个类，可以通过注释main中1然后修改Stu类实现有无transient关键字修饰、serialVersionUID是否不同，得到以下结果： 1、serialVersionUID的数值大小不会影响序列化后的字节数大小 2、transient的有无，会影响序列化后的字节数大小，有transient修饰成员变量，字节数会变小，反之变大 3、若某成员变量没有被transient修饰，则该成员变量不能被反序列化，打印结果为null import java.io.*; public class SerializableDemo {

As an AI language model, I don't have enough context to determine the exact issue you are facing. However, here are some possible reasons why '@DefaultValue' is not applicable to a field: 1. '@DefaultValue' is not a valid annotation in the programming language or framework you are using. Make sure that you are using the correct syntax or check the documentation for the valid annotations. 2. The field you are trying to apply '@DefaultValue' to is not a property or a method. Annotations are usually applicable to methods or properties, so make sure that you are using it correctly. 3. The version of the programming language or framework you are using does not support '@DefaultValue'. Check the version of the language or framework and see if it supports this annotation. 4. You might have misspelled the annotation. Double-check the spelling and make sure that you are using the correct case. If none of these solutions work, please provide more context, and I can try to assist you further.
