当属性是对象的时候,如果这个对象,没实现序列化接口,那么上面的方法在序列化的时候就在执行oos.writeObject(flyPig)时候,报错了“Exception in thread “main” java.io.NotSerializableException: com.lxk.model.Bird”。然后给刚刚的属性的对象加上实现序列化的接口之后,上面的测试就正常通过了。你这个问题问的好。

在Java中,Serializable接口是一个标记接口,它没有任何方法需要实现。我们只需要在类的声明中使用implements Serializable语句即可。示例如下: AI检测代码解析 publicclassPersonimplementsSerializable{// 类的定义...} 1. 2. 3. 在上面的示例中,我们将Person类实现了Serializable接口。现在,我们就可以将Person对象转化为...
