serializable interface

First, why to serializeBefore we introduce, we need to understand the life cycle of the object, we know the life cycle of the Java object, that is, The remote method call RMI in Java will also be used, In order to transfer objects in the network,

Last weekend, the basics of Java have done a collation, where the Java serialization and deserialization of the data in detail, here to make a note, I hope to also help to read this article friends. First, the concept of serialization and

Java face test-Basic Article Five 41, A.hashcode () what is the use. What is the relationship to A.equals (b).The Hashcode () method corresponds to the hash value of the integral type of the object. It is commonly used in hash based collection

There are two ways to pass Java objects in Android intent: first, by calling the Putserializable (Key,object) method of the Bundle object " See Example ", The other is by calling the Putparcelable (Key,object) method of the Bundle object " See

1. Meaning:Save the state of an object (the quantity of attributes), and obtain it when appropriate.2. programming requirements:Only class objects that implement the serializable interface can be serialized. The serializable interface does not

Here are some summary of some of the complex objects:L when the parent class inherits the serializable interface, all subclasses can be serialized the L subclass implements the Serializable interface, the parent class does not, the attribute in the

An object serialization interface. A class can be serialized only when the serializable interface is implemented. Therefore, to serialize objects of some classes, these classes must implement the serializable interface. In fact, serializable is an

Java serialization and deserialization, Java serialization 1. What is serialization? Why serialization? JavaSerializationIt refers to the process of converting an object into a byte sequence, andDeserializationThe process of converting the byte

1. Object Stream: writes or reads an object directly. 2. Serialization: convert the object directly into a byte stream to write to the hard disk or Network. 3, If you want to convert an object into a byte stream, the Object's entity class must

First, the concept and purpose of serialization1. What is serialization?Serialization (serialization) is a concept in computer science that refers to storing objects in media (such as files, intrinsic buffers, etc.) or transmitting them over the

One, Java streaming input/output principle　　Stream is used to read and write data, Java has a class called file, it encapsulates the filename of the files, just an object in memory, the real file is a piece of space on the hard disk, in this file

The system has organized a bit of questions about Java, including Basic, Javaweb, frame, database, multi-threaded, concurrent articles, algorithms and so on, updated in succession. Other aspects such as the front end and so on the face of the

Java Basic Learning Summary-stream One, Java streaming input/output principle　　Stream is used to read and write data, Java has a class called file, it encapsulates the filename of the files, just an object in memory, the real file is a piece of

An object-serialized interface in which the object of a class is serializable only if it implements the serializable interface. So if you want to serialize objects of some classes, these classes must implement the Serializable interface. In fact,

Serializable, has been used before, the default entity class will implement the Serializable interface, for the specific reason has not been very understanding, and if not implemented serialization, also has no effect, when should be serialized

Overview Java serialization serialization, we should be not unfamiliar. Its main function is to transform the state of an object into a sequence of bytes to facilitate the persistence of objects or network transmission. The reverse is the reverse

For an object that exists in a Java virtual machine, its internal state remains in memory only. After the JVM has stopped, these states are lost. In many cases, the internal state of an object needs to be persisted. When it comes to persistence, the

When two processes are communicating remotely, each other can send various types of data. Regardless of the type of data, it is transmitted over the network in the form of a binary sequence. The sender needs to convert the Java object to a sequence

ObjectiveSerialization and deserialization do not seem to be used much, but it is critical to use it because there is a problem with a little attention. Where is the serialized application scenario? Data is stored and transmitted, of course. such as
