What is meaning Serialize in java?
Primary purpose of java serialization is to write an object into a stream, so that it can be transported through a network and that object can be rebuilt again. When there are two different parties involved, you need a protocol to rebuild the exact same object again. Java serialization API just provides you that. Other ways you can leverage the feature of serialization is, you can use it to perform a deep copy. Why I used 'primary purpose' in the above definition is, sometimes people use java serialization as a replacement for database. Just a placeholder where you can persist an object across sessions. This is not the primary purpose of java serialization. Sometimes, people say that java serialization is used for storing (to preserve the state) an object and retrieving it. They use it synonymously with database. This is a wrong perception for serialization.
What is deserialization in java?
De-serialization is the opposite process of serialization. This is the process where we convert data that has already been written out onto a stream as part of serialization into Java objects.
How is Java persistence done?
Java persistence is implemented using serialization. Serialization is a technique in java using which the contents of a java object (A class instance) can be written into a flat file. This value can be unserialized or deserialized at a later point of time to create the object. Any class that implements the Serializable interface can be serialized.
What are the Topics under Advanced Java?
Some topics under Advanced Java are: a. Exception Handling b. Threading/Multi-Threading c. Remote Method Invocation d. Serialization e. etc
What is serialization in Java?
Serialization is the ability to easily store the state of an Object in memory onto some long-term medium (on a hard drive, for example). Basically, the Serializable interface allows us to tell Java to turn our Object into a byte-stream. The Object could be a document that the user is working on, or a more complex data class which needs the ability to be saved to the hard drive. Using the Serializable interface (and related I/O methods), Java will do most of the work for us.
What is meaning of word persistence in java?
Persistence is the term used to refer to the situation where the objects data is stored even after the object is destroyed or the application is closed. Persistence is implemented using Serialization where the data of the object is serialized into flat files and stored into the system. These files can be de-serialized to form the objects by using de-serialization.
Can you use pointers in java?
Java does not support Pointers and hence you cannot use it in Java.
Who is responsible for updating UII data for all in-use serialization records?

What is serialization in NET What are the ways to control serialization?
SerializationSerialization is a process of taking an object and converting into a form so that it can be transported across the network or can be persisted in the storage location. This storage location can be physical file, database or ASP.NET Cache. The form contains the state of the object so that by this format, we can construct the same object a later point in time, which is called Deserialization. There are three formats of serializationBinary Serialization : Light and compact used in RemotingSOAP Serialization : interoperable use SOAP and used in web ServicesXML Serialization : Custom SerializationXML SerializationFor XML serialization, you need to use the attributes and specify them for each and every public member that you need. But since it is limited that it can serialize only public members, Serization done by it is called custom serialization. It is also known as Shallow SerializationSOAP and Binary SerializationXML serializes only public members of the class. You use SOAP or Binary serialization when you need to transport data across the network. SOAP sends it using HTTP Protocol which makes it most interoperable while Binary serialization is known for its light and compact nature. Web Services uses the SOAP Serialization and Remoting uses the Binary Serialization. Infact Serialization is always necessary when you need the object to transfer across a network. Advantage of using the SOAP or Binary serialization is that you can serialize the entire object and all those object that are being refrenced by it. This is why it is also called Deep Serialization. If you want any class to serialize through any of these methods then you should use [Serializable] attribute on that class and then you can use the SoapFormater class or BinaryFormatter class to do the serialization. These classes have Serialize and DeSerialize method. If you will not use SerializableAttribute for the class, then it will raise the exception.Though this is the easiest way but at time you need the way so that you can decide what fields to serialize and how the serialization actually occurs. You can implement the ISerializable interface in the class. You need two things for thatConstructor that is overridden and can handle the Deserialization processGetObject method that tracks about which data is serialized.A small example below illustrate this all.public class Employee :ISerializable{private int emp_no;private string name;protected TestData(SerializationInfo info,StreamingContext context){this.emp_no = info.GetInt32("emp_no");this.name = info.GetString("name");}void ISerializable.GetObjectData(SerializationInfo info,StreamingContext context){info.AddValue("emp_no", this.emp_no);info.AddValue("name", this.name);}}}
