OOP is a design philosophy. It stands for Object Oriented Programming. Object-Oriented Programming (OOP) uses a different set of programming languages than old procedural programming languages (C Dallas Goedert Eagles Jersey , Pascal, etc.). Everything in OOP is grouped as self sustainable "objects". Hence, you gain reusability by means of four main object-oriented programming concepts.
In order to clearly understand the object orientation model, let鈥檚 take your 鈥渉and鈥?as an example. The 鈥渉and鈥?is a class. Your body has two objects of the type "hand", named "left hand" and "right hand". Their main functions are controlled or managed by a set of electrical signals sent through your shoulders (through an interface). So the shoulder is an interface that your body uses to interact with your hands. The hand is a well-architected class. The hand is being reused to create the left hand and the right hand by slightly changing the properties of it.
What is an Object?
An object can be considered a "thing" that can perform a set of related activities. The set of activities that the object performs defines the object's behavior. For example Dallas Goedert Kids Jersey , the Hand (object) can grip something, or a Student (object) can give their name or address. Best core java training in Bangalore

In pure OOP terms an object is an instance of a class.
What is a Class?
A class is simply a representation of a type of object. It is the blueprint, or plan, or template, that describes the details of an object. A class is the blueprint from which the individual objects are created. Class is composed of three things: a name Dallas Goedert Youth Jersey , attributes, and operations.
In real world, you'll often find many individual objects all of the same kind. As an example, there may be thousands of other bicycles in existence, all of the same make and model. Each bicycle has built from the same blueprint. In object-oriented terms Dallas Goedert Womens Jersey , we say that the bicycle is an instance of the class of objects known as bicycles.
In the software world, though you may not have realized it, you have already used classes. For example, the TextBox control, you always used Authentic Dallas Goedert Jersey , is made out of the TextBox class, which defines its appearance and capabilities. Each time you drag a TextBox control, you are actually creating a new instance of the TextBox class. Advanced Java Training in Bangalore


How to identify and design a Class?
This is an art; each designer uses different techniques to identify classes. However according to Object Oriented Design Principles, there are five principles that you must follow when design a class,
鈥?SRP - The Single Responsibility Principle -
A class should have one Dallas Goedert Jersey , and only one, reason to change.
鈥?OCP - The Open Closed Principle -
Should be able to extend any classes' behaviors, without modifying the classes..
鈥?LSP - The Liskov Substitution Principle-
Derived classes must be substitutable for their base classes.
鈥?DIP - The Dependency Inversion Principle-
Depend on abstractions, not on concretions.
鈥?ISP - The Interface Segregation Principle-
Make fine grained interfaces that are client specific.
Additionally to identify a class correctly, you need to identify the full list of leaf-level functions or operations of the system (granular level use cases of the system). Then you can proceed to group each function to form classes (classes will group same types of functions or operations). However a well-defined class must be a meaningful grouping of a set of functions and should support the reusability, while increasing expandability or maintainability, of the overall system.
In software world the concept of dividing and conquering is always recommended, if you start analyzing a full system at the start, you will find it harder to manage. So the better approach is to identify the module of the system first and then dig deep in to each module separately to seek out classes.
A software system may consist of many classes. When you have many classes, it needs to be managed. Think of a big organization#7# with its work force exceeding several thousand employees (let鈥檚 take one employee as one class). In order to manage such a work force, you need to have proper management policies in place. Same technique can be applied to manage classes of your software system. In order to manage the classes of a software system, and to reduce the complexity, system designers use several techniques, which can be grouped under four main concepts named
鈥?1. Encapsulation
鈥?2. Abstraction

Polymorphisms is a generic term that means 'many shapes'. More precisely Polymorphisms means the ability to request that the same operations be performed by a wide range of different types of things.
At times, I used to think that understanding Object Oriented Programming concepts have made it difficult since they have grouped under four main concepts, while each concept is closely related with one another. Hence one has to be extremely careful to correctly understand each concept separa .
