Core Java & Serialization Mechanism!

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.

Learn OOPs & All Java Concept At LotuITHub?

In the interview, the usual question you face is regarding “Object-Oriented Programming” (OOP) which is associated with concepts like class, object, inheritance, encapsulation, abstraction, polymorphism, etc.

Learn OOPs & All Java Concept At LotuITHub

Java is one of the sought-after languages for beginners and professionals also. But the heck is for what classes, objects and methods are used? Why do we need inheritance and polymorphism? and more. At Java classes in Pune, an aspirant can learn everything about the OOPs, in detail.

  • Inheritance

In the Inheritance class properties of one class can be inherited by the other where reuse of code is possible to establish relationships between different classes. As we know in the biological system due to DNA child inherits some of the parent properties. Similarly, here “Child Class” (Subclass or derived class) inherits the properties from the “Parent Class” (Super or base class), inheritance is further classified into four types:

Let’s understand the concept with examples, where, Class A is your parent class and Class B is your child class

  1.       Single Inheritance

Example

Class A {—}

Class B extends A {—}

  1.       Multilevel Inheritance

Please find the example below, where, A is the parent class for B and class B is the parent class for C.

Example

Class A {—}

Class B extends A {—}

Class C extends B {—}

  1.       Hierarchical Inheritance

Please find the example below, where, Class B and C are the child classes that are inheriting from the parent class i.e Class A.

Class A {—}

Class B extends A {—}

Class C extends A {—}

  1.       Hybrid Inheritance

Class A and B extends class C → Hierarchical inheritance

Class D extends class A → Single inheritance

class C {

   public void disp() {

System.out.println(“C”);

   }}

class A extends C{

   public void disp(){

System.out.println(“A”);

}}

class B extends C{

   public void disp(){

System.out.println(“B”);

   }}

class D extends A{

   public void disp(){

System.out.println(“D”);

   }

   public static void main(String args[]){

D obj = new D();

obj.disp();

}}

  • Encapsulation

We can achieve encapsulation in Java by:

  1. Variable of the class are private.
  2. Public setter and getter methods are defined to modify and view the variable’s values.

Example

public class Employee {

 private String name;

 public String getName() {

 return name;

 }

 public void setName(String name) {

 this.name = name;

 }

 public static void main(String[] args) {

 }}

 

  • Abstraction

At Java coaching classes in Pune, an aspirant will learn the abstraction concept of Java programming in two ways:

  1.       Abstract Class

For the abstraction, you need to inherit the class from another class

The syntax of an abstract class:

Abstract class Mobile {   // abstract class mobile

Abstract void run();      // abstract method

 

  1.       Interface

In the abstraction class, an interface is a group of related methods with empty bodies.

Example

public interface ParentCar {

public void changeGear( int newValue);

public void speedUp(int increment);

public void applyBrakes(int decrement);

}

  • Polymorphism

Java training institutes in Pune is the best place to understand the keen concepts of Java programming with real-life examples. Polymorphism defines one interface or method with multiple implementations.

Polymorphism in Java is of two types:

  1.       Runtime polymorphism

Example

public Class BowlerClass{

void bowlingMethod(){

System.out.println(” bowler “);

}

public Class FastPacer{

void bowlingMethod(){

System.out.println(” fast bowler “);

}

Public static void main(String[] args){

FastPacer obj= new FastPacer();

obj.bowlingMethod();

}}

  1.       Compile time polymorphism

Example

class Adder {

Static int add(int a, int b){

return a+b;

}

static double add( double a, double b){

return a+b;

}

public static void main(String args[]){

System.out.println(Adder.add(11,11));

System.out.println(Adder.add(12.3,12.6));

}}

Java Inception To Future Perception!

Java has always been a bashing programming language by many measures no matter what statistics market shows or whether people think that Java is now growing, stagnating, or dying still everyone has to accept it that Java had truly revolutionized and the LotusITHub’s Java Certification will definitely make you stand in the 21st century’s programming platform.

Java Inception To Future Perception

Java has flourished and brought the masses towards the programming language with the combined features that were previously available only separately or in various niche languages that you will understand and learn at Java classes in Pune.

Inception

Java has emerged in the late 90’s with its competitive languages like Haskell, Delphi, JavaScript Python, Ruby, PHP, etc. At the early stage, Java was striving to become a language for the “interactive Web” but unfortunately, JavaScript become the one but in its second inning, Java established its foothold in desktop application development and become one of the favorites for industries backend development.

Development of the huge application is considered in Java then and now as well, being the only language with the features like memory safety and automatic garbage collection. Java is an error-free language or it has fever chances of error creation as different kinds of reference and array-related failures in the Java are easier to identify and to troubleshoot and it is a big gift for desktop applications. Reading it is quite easy and on the same way At Java training institute in Pune aspirant will learn to execute the Java applications.

At Java classes, you will learn the Java’s ability to dynamically load code while maintaining the API’s that are object-oriented binary compatible were applicable for the “interactive web” and still proved to be invaluable for the backend. Gradually the term “application server” had taken the place of “Java application server” and ruled the backend world by shifting the micro-service architecture with the emergence of virtualization and containers.

Java’s Integrated Development Environment (IDE) becomes a big desktop UI application with various plugins which are the combination of static typing, managed memory, dynamic code loading, and cross-platform-ness that allows Java to scale up development and build such kind of feature-rich IDEs.

Initially designed Java was not included with micro-system or pre-processor because the only focus at that time was simplicity and cross-platform but with the demand made Java an exceedingly well suited to safeguard and automate refactoring in IDE. Java course in Pune will help to understand the automated nature of Java on the individual platform.

Perception

As with the passing year software development landscape is changing every sector and are getting revolutionized including the area that Java has captured eventually are also getting transformed. Desktop development is becoming more professional and enterprise-oriented where mass-market consumers are looking forward to the web and mobile applications. Yet, Java is never going to be out of date moreover, Java’s immense impact is here to stay and to dominate the landscape in the coming future.  To capture this future perception Java training in Pune is going to be your path maker that will help you to pave the journey with ease.

LotusITHub institute is situated in Pune at Karve Nagar, Warje, Dhayari, Kothrud, Narhe, and at many other places, for quick inquiry, you can visit our website and can give a personal visit at any of these places. Java coaching classes will be going to be a pathmaker for the learner as the Java ingredient you will learn here will drive you around the millennium applications of Java. Long live Java!
