serializable interface

Data transfer between the activityData transfer between activity we can transfer many different types of data through the Putextra method of the intent object, such as strings, integers, real numbers, objects, and so on.First, take a string for

What is serialization? Serialization is to save the state of an object (the quantity of each attribute), and then obtain it when appropriate. Serialization is divided into two parts: serialization and deserialization. Serialization is the first

The serialization of a Java object is one of the methods of turning an object into a binary data stream, which can be easily transferred and stored by the serialization of the object.The principle is: Object-------------> Transform----------------->

Solution: Explicitly specify in the classPrivate static final long serialversionuid = 42L;class implements the serialization interface, and when serialization is deserialized, throws a Java.io.InvalidClassException

JavaBeans To understand the serializable interface, first understand the basic JavaBeans. JavaBeans provides us with the simplest Java-class entities that accompany the business to and fro in applications. JavaBeans is a special class in Java that

An in-depth discussion of Java object Cloning (clone) and cloneable interface and serializable interfacePart IThere's nothing to say, just start Part II.Part IIWhen it comes to cloning an object, you have to say why you want to clone the object. All

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.

The serialization runtime is associated with each serializable class using a version number called Serialversionuid, which is used during deserialization to verify that the sender and receiver of the serialized object have loaded a

There is always a lot of things to be used for project development. It is not a short time for a new knowledge to come out, but a new one for yourself. Therefore, you need to learn it by yourself, it is hoped that the learning efficiency will be

When data is transmitted between activities, in order to avoid the trouble, some values are often encapsulated into objects, and then the entire object is passed over. The Parcelable interface and the Serializable interface can be implemented when

When data is passed between activity, in order to avoid trouble, some values are often encapsulated as objects, and then the entire object is passed through. When transmitting an object, there are two cases, one is to implement Parcelable interface

Today, I encountered a problem in my android experiment. It took more than one hour to locate the problem and solve it. This problem is relatively hidden and will waste a lot of time if you don't know it. First look at the Code: In newslistactivity.

When data is transmitted between activities, in order to avoid the trouble, some values are often encapsulated into objects, and then the entire object is passed over. The parcelable interface and the serializable interface can be implemented when

What is the serializable interface. An object-serialized interface in which a class can be serialized only if it implements the serializable interface. What is serialization. The process of converting the state information of an object into a

 Java serialization and deserialization  1 OverviewObject serialization refers to the process of converting an object into a byte sequence, while deserialization refers to the process of recovering an object based on the byte

Introduction:If you only know the object implementing the serializable interface, you can serialize it to a local file. You 'd better read this article again.ArticleThe article further discusses serialization with actual examples.CodeThis article

When a parent class implements the serializable interface, its sub-classes are automatically serialized. This is verified as follows: Package serial;Import java. Io. serializable;Public class superc implements serializable {// The parent

Reprinted fromHttp://www.blogjava.net/jiangshachina/archive/2012/02/13/369898.html The article on Java serialization has long been full of resources. This article is a summary of my past studies, understanding and application of Java serialization.

When a parent class implements the Serializable interface, its sub-classes are automatically serialized.This is verified as follows:Package Serial;Import java. io. Serializable;Public class SuperC implements Serializable {// The parent class
