serialization, deserialization (an entity class or an object class to be serialized must implement the Serializable interface)

 PackageCom.phone.shuyinghengxie;Importjava.io.Serializable;/*for a class object to be serialized successfully, two conditions must be met: the class must implement a Java.io.Serializable object. All properties of the class must be serializable.                If there is a property that is not serializable, the attribute must be noted to be short-lived.                If you want to know if a Java standard class is serializable, see the documentation for that class.
