Objected Oriented Language - Basic Features


Object oriented programming

In order for you to fully gain the skills of a developer, you'd have to grasp the object-oriented mindset and all it entails, if you fail to do so, you will have a hard time trying to create your applications and become a multimillionaire, unless of course you have a nice capital and you are able to find a good software developer that can help you with your application development needs.

In today's article we are going to talk about the fact that many of us who call ourselves programmers still need to remind ourselves of some of the important features of object-oriented programming.

The object-oriented style of programming has recently become the most used programming paradigm among many software and website developers around the world.

As systems become increasingly complex and large in size, the object-oriented style of programming had to be created, because these complex and large systems need to be upgraded and changed over time and doing so using the procedural programming could lead you into a lot of trouble.

Object-oriented style of programming had to be created because it provides software and website developers the ability to better manage and upgrade these large and complex systems.

The other style of programming that you will encounter as you travel on your journey to become a master programmer, is the procedural programming.

The procedural style of programming is only being used by software and website developers who still want to use the old school style of programming to create applications for the cyber world.

We are not going to go to much into detail about procedural programming because we want to explore the important features of object-oriented programming.

In object-oriented programming everything is organized around objects instead of actions and data instead of logic.

Logic is very difficult to formulate on the spot when you are using a programming language to create the next big thing from you to the world, which is why the logic of your programming in object-oriented is usually already there for you, you just have to learn how to use these logics.

Logic is used in object-oriented programming though, please don't misunderstand that you will get away with having to formulate your own logic, because you will have to formulate your own logic.

What we mean when we say that objects and data are the center of object-oriented programming is that you'll find it easer to program your applications using object-oriented programming if you understand the basics of objects, methods, classes as well as many other important features of object-oriented programming.

Remember though, don't rush the process and let it be built inside of your inter intelligence, so that it may stay once you become that software and website developer you are looking to become.

Before you jump into the depth of programming, it will help you to know certain basics of object-oriented programming language.

Such important basics of object-oriented language are also: syntax rules, which can be different with each and every computer language that you may be using.

You will have to challenge your mind skills and see if you are worth something when you program using object-oriented style of programming.

The only way that you will be able to improve your mind and programming skills though is by developing simple and not so simple programs.

If you really want to improve your programming logic, get to programming, but of course before you do that make sure that you are familiar with important feature and algorithms that could prove to be helpful when you are stock thinking about your code.

Alright let's explore some of these important features that we can find in object-oriented programming language.

Object-oriented programming languages provides software developers the ability to improve and simplify their program when they use encapsulation, inheritance and polymorphism.

Encapsulation in object-oriented programming is the process of combining elements so that they work together and create a new entry that has restricted access.

The concept of encapsulation is to guarantee the integrity of the data that is contained inside an object.

The integrity of the data is accomplished by concealing the way an object is implemented, by organizing methods and data into a predefined structure.

Encapsulation hides your data and prevents users from modifying attributes, instead users have to use the defined functions; thus ensuring data integrity.

Access levels for elements of a class are also defined by encapsulation; so that users have limited or full access to certain data.

The levels of data access that encapsulation defines are public, which can be accessed by functions of all classes and is the lowest level of protection.

The other access level is protected, which limits access of data to functions of the class or sub-classes; only through inheritance, can another class have access to a protected data of another class.

The last data access level is private and this data is restricted to methods of a particular class.

The private data access level is considered to be the highest level of data protection and integrity, so if you want to make sure that you data is fully protected use private as your data's access level.

Alright for now we assume that you are clear about what encapsulation is, but if you don't please do visit the website often and contact us so that we may help you understand this and other questions you may have.

Alright now let's talk inheritance, the concept of inheritance is based on the fact that classes are allowed to use certain states and behaviors from other classes.

Before we continue, we do hope that you know what object, classes and methods are because we do assume that know these very important concepts of object-oriented (OOP) programming languages, but if you don't please do some research here or online and find out more about these very important features of OOP.

Anyhow, back to the fact of the matter, inheritance allow new classes to receive or inherit the properties and methods of an already existing class in OOP language.

The relationship that would exist between two classes or blueprints to build specific object are represented through an inheritance.

Inheritance gives you, the application developer, the ability to avoid starting from scratch when you want to build an object that is similar to one that already exist, all you would have to do is specify the difference between your newly created class and the class that already exist.

A superclass or base class is the class that is used as the basis for an inheritance, and a sub-class or derived class is the class that inherits the methods and properties from the superclass.

Additionally to the methods and properties that a subclass would inherit from a supper class the sub-class also adds its own properties and methods to extend the class, these properties and methods are added by you of course and here is where your logic abilities would have to come in handy.

You should have a clear understanding of inheritance by now, but if you don't, please don't hesitate to contact us and we'll get back to you as soon as possible.

Anyhow, let's now talk polymorphism and what it means in OOP languages; the ability to process objects based on data types or class is known as polymorphism.

This is how derived classes are able to redefine methods from super-classes for their own purpose.

If you were to analyze the word polymorphism, you'll find that poly means several or more than one, and morphism means form.

Therefore in OOP languages, methods and properties have the ability to take on different behaviors, which are declared by you, although they may have the same names.

You will find that objects of classes are inherited from the same common base class, or belong to the same hierarchical tree.

All attributes and behaviors of a general class can be passed down to sub-classes; therefore, making the job of a software developer much easier.

See when you are an experienced programmer you'll find that it is very easy to break your code when you need to modify it.

However, when you use polymorphism, you'll be able to extend classes, by creating more specific sub-classes with certain and unique attributes and behaviors.

The reason why you won't be able to break your own code and have to start all over again, is because you'll be able to alter a specific function of your code and not the entire system.

So there you have it, you should know now and have some grasp of why we use and prefer to use object-oriented programming languages when it comes to building and developing state of of the art systems and applications.

Applications can certainly have a lot of lines of coding and if you don't have a good environment in place to be able to write your code proficiently you'll be in deep trouble.

Trust me, always seek out the facts first, do a lot of reading and then plan the code of your application, as well as write your coding.

See when you become a programmer you learn that planning is very important and skipping this part of the whole programming life/development cycle could cost you energy, effort, time and money.

Learn object-oriented programming language and master your skill so that you are an asset to yourselves and is able to create some state of the art technology that we have yet to see.

If you've never used an object-oriented programming language before, you'll need to learn a few basic concepts before you can begin writing any code. An object is a software bundle of related state and behavior. Software objects are often used to model the real-world objects that you find in everyday life. Objects are key to understanding object-oriented technology. Look around right now and you'll find many examples of real-world objects: your dog, your desk, your television set, your bicycle. Real-world objects share two characteristics: They all have state and behavior.

Dogs have state (name, color, breed, hungry) and behavior (barking, fetching, wagging tail).

Bicycles also have state (current gear, current pedal cadence, current speed) and behavior (changing gear, changing pedal cadence, applying brakes). Identifying the state and behavior for real-world objects is a great way to begin thinking in terms of object-oriented programming.

A class is the blueprint from which individual objects are created.

In the real world, you'll often find many individual objects all of the same kind. There may be thousands of other bicycles in existence, all of the same make and model. Each bicycle was built from the same set of blueprints and therefore contains the same components. In object-oriented terms, we say that your bicycle is an instance of the class of objects known as bicycles.

The syntax of the Java programming language will look new to you, but the design of this class is based on the previous discussion of bicycle objects. The fields cadence, speed, and gear represent the object's state, and the methods (changeCadence, changeGear, speedUp etc.) define its interaction with the outside world.

You may have noticed that the Bicycle class does not contain a main method. That's because it's not a complete application; it's just the blueprint for bicycles that might be used in an application.

The responsibility of creating and using new Bicycle objects belongs to some other class in your application.

Example of a class.

class Bicycle {

int cadence = 0;

int speed = 0;

int gear = 1;

void changeCadence(int newValue) {

cadence = newValue;

}

void changeGear(int newValue) {

gear = newValue;

}

void speedUp(int increment) {

speed = speed + increment;

}

void applyBrakes(int decrement) {

speed = speed - decrement;

}

void printStates() {

System.out.println("cadence:" +

cadence + " speed:" +

speed + " gear:" + gear);

}

}
