[Java interview Question ] Java provides a mechanism, called object serialization where an object can be represented as a sequence of bytes that includes the object's data as well as information about the object's type and the types of data stored in the object. After a serialized object has been written into a file, it can be read from the file and deserialized that is, the type information and bytes that represent the object and its data can be used to recreate the object in memory. Most impressive is that the entire process is JVM independent, meaning an object can be serialized on one platform and deserialized on an entirely different platform. Classes ObjectInputStream and ObjectOutputStream are high-level streams that contain the methods for serializing and deserializing an object. The ObjectOutputStream class contains many write methods for writing various data types, but one method in particular stands out: public final void writeObject(Object x) throws IOException The above method serializes an Object and sends it to the output stream. Similarly, the ObjectInputStream class contains the following method for deserializing an object: public final Object readObject() throws IOException, ClassNotFoundException This method retrieves the next Object out of the stream and deserializes it. The return value is Object, so you will need to cast it to its appropriate data type. 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. How do you serialize? When you want to serialize an object, that respective class should implement the marker interface serializable. It just informs the compiler that this java class can be serialized. You can tag properties that should not be serialized as transient.

Welcome to www.InterviewDot.com Java Interview Questions and Answers : Job portal -- Java Tutorial / Interview Why do we need Java Serialization ? Job Java Interview Question : Serialization 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. OBJECTS ? STREAM OF BYTES Using serialization ,two different process can transfer OBJECTS between each other. Now the problem is the Network infrastructure and your Hard disk are hardware components that understand bits and bytes but not JAVA objects.
