Core Java & Serialization Mechanism!

by lotusithub

Java is the globally used object-oriented programming language and OOPs concept is the building block of JAVA with the four basic pillars i.e., Abstraction, Encapsulation, Inheritance, and Polymorphism. Java Classes in Pune will enable you to OOPs along with the Java control statements that include for, do, do-while, if-else, Switch case, continue and break statements etc.

In order to handle the collection of objects, JAVA provides the collection APIs with inbuilt classes and interfaces to handle the collection of objects. In the Java training in Pune, the experts will make you aware of the multithreading concept, to perform two or more task concurrently. In JAVA 5 there is java.util.concurrency package is given for developing the multithreaded application.

Serialization is one of the most important concepts frequently asked in the interview. We will discuss in detail about the mechanism called serialization and aspirant can take practical tutorials with the handy assignments on the same at Java classes in Pune.

As per the standard definition, “Serialization is a mechanism of converting a state of an object into a byte stream.” The mechanism is used to persist the Java object in a form of a sequence of bytes that includes object’s data and the data stored in the object. In the core Java, there is also a concept of deserialization which is the reverse process of serialization where the byte stream is used to recreate the actual Java object in memory. The serialized object can also be deserialized using the object’s type and other information to retrieve the original object.

During Java certification in Pune, the student will learn from the scratch where experts will guide them to understand the Classes ObjectInputStream and ObjectOutputStream streams for serializing and deserializing the object.

The commonly used serializing method from the ObjectInputStream is:

 

private void writeObject(ObjectOutputStream os) throws IOException

{

}

 

Similarly following is also one of the methods used in Java Serialization

private void readObject(ObjectInputStream is) throws IOException, ClassNotFoundException

{

}

 

The Need of Java Serialization

When the user needs to send or receive the data in the form of objects over the network or to store in a file then, serialization is used. Serialization is basically the translation of java objects values which are sent over the network or to save it. The entire serialization process in Java works independently in JVM where an object can be serialized on one platform and deserialized on an entirely different platform. When you serialize any object and if it contains any other object reference then Java serialization serialize that object’s entire object graph, this you can learn at Java course in Pune. It follows the inheritance concept which implies if superclass is Serializable then its subclasses are automatically Serializable and all values of the instance variables inherited from superclass will call the constructor of Non-Serializable Super class during the deserialization process.

At LotusITHub Java coaching classes in Pune, we have different industry experts who conduct the classes and guide the aspirant for the betterment of their future. Whether you are fresher or experience, you can visit our institute to learn from scratch. LotuITHub has branches across the breadth of the Pune, you can visit our Java classes at Karve Nagar, Kothrud, Warje, Narhe, and Dhayari for demo session at any time. For the overview, you can visit the website at www.lotusithub.com and post us feedback.
