Objectoriented programming lecture notes download b. Each object has its own memory made up by other objects. Included hundreds of useful examples provides complete guidance for the students to learn object oriented programming technique for. Since the class is wellencapsulated compared with the function, it is easier to reuse these. The idea of this book was to focus on practical aspect of programming. In the video below, we have explained the basic concepts of object oriented programming with help of a very easy to.
Emphasis has been laid on the reusability of code in objectoriented programming and how the concepts of class, objects, inheritance, polymorphism, friend. Objectoriented technology is both an evolution and a revolution as evolution it is the logical descendant of hll, procedures, libraries, structured programming, and abstract data types. If you are new to object oriented approach for software development, an object in oop has some state and behavior. It covers basic topics like inputoutput streams, namespaces, classes and objects, constructors, function overloading, function overriding through to advanced topics such as inheritance, polymorphism, templates, exception handling, file handling etc. The concept of an invariant is fundamental to objectoriented programming, because it provides information on the overall. Need for object oriented programming objectoriented programming scales very well, from the most trivial of problems to the most complex tasks. Then you can start reading kindle books on your smartphone, tablet, or computer no kindle device required. Now well take a step back and consider the programming philosophy underlying classes, known as objectoriented programming oop. These features are generally referred to as the oops concepts. Objectoriented programming is the most recent concept among programming paradigms and still means different things to different people. A program is a set of objects telling each other what to do by sending messages.
Objectoriented programming oop consist of some important concepts namely encapsulation, polymorphism, inheritance and abstraction. After a call for participation, several highly motivated people from all over the world joined course coordinator marcus speh. It provides a form of abstraction that resonates with techniques people use to solve problems in. All objects of a specific type can receive the same messages. Object is an instance of class object combines data and functions object is created as a variable of class type using class name members of class. Fundamental packaging unit of oop technology class declaration is similar to struct declaration keyword class followed by class name.
Objectoriented programming oop languages are designed to overcome these problems. Objectoriented programming has several advantages over procedural. After a call for participation, several highly motivated people from all over the world joined course coordinator marcus speh as consultants and had pushed the course to its success. Procedural programming is about writing procedures or functions that perform operations on the data, while objectoriented programming is about creating objects that contain both data and functions. Introduction to object oriented programming, user defined types, structures, unions, polymorphism, encapsulation. Classes and objects i class user defined data type. Java is a unique language and it has all the features which makes it the language of the 21st century. Programming techniques procedure oriented programming procedural vs. We are aware of astounding features of objectoriented programs. As object oriented language, it offers bottom to top approach. It is a userdefined data type, which holds its own data members and member functions, which can be accessed and used by creating an instance of that class. An object oriented implementation of stack using arrays in.
