The authors stress incremental program development, wherein program analysis is followed by building a structure chart, constructing UML flow diagrams, writing algorithms, undertaking program design, and finally testing. This foundation, combined with a focus on the benefits of a consistent and well-documented programming style, prepares students to tackle the academic and professional programming challenges they will encounter down the road with confidence. E-Book Description. E-Book Details.
Table of Contents. A class that is utilized as the reason for legacy is named a superclass. A class that acquires from a superclass is named a subclass or determined class. Parent class and youngster class are likewise adequate terms. Legacy gives OOP code reusability and is utilized to accomplish runtime polymorphism. Polymorphism is the place a solitary assignment can be performed in various ways. This implies OOP has the ability to choose the correct called work at runtime relying upon the present setting.
There are two kinds of polymorphism; abrogating and over-burdening. Abrogating run-time polymorphism is the place two techniques have a similar strategy name and parameters i.
One strategy is in the parent class and the other is in the youngster class. Over-burdening arrange time polymorphism happens when at least two strategies in a single class have a similar strategy name however extraordinary parameters. Reflection is the place a software engineer can hide everything aside from the applicable information around a question keeping in mind the end goal to diminish intricacy and increment effectiveness.
As it were, speaking to highlights without including foundation subtle elements or clarifications. For example, in Java, an object oriented programming language, a method can be defined which when executed will return a value of a certain type. The return type can be dependent on the arguments that were supplied during the call. For instance, if there is an object oriented programming technique, which uses an overloaded operator, the programmer may decide to change the operators so that they can return different types, for instance an int can be returned instead of a float when an int is needed rather than a float when a double is needed.
Another object-oriented programming concept is encapsulation. Encapsulation is the act of handling an abstract concept. In the case of an object-oriented language, an encapsulation can be achieved by defining and utilizing interfaces. When dealing with an imperative language, dealing with encapsulation is not as easy because the programmer must consider each possible syntactic syntax or keyword when determining how to encapsulate a variable or function.
For an object-oriented programming concept however, the use of interfaces makes encapsulation easy. Object Oriented Programming can be seen as a set of techniques that enable an individual to reuse code and implement the same object-oriented program from different perspectives. For example, let us look at an object oriented programming language that uses inheritance.
Inheritance refers to the process where one entity is derived from another entity. When inheritance is applied to an object oriented programming concept, it results in creating a new class that is derived from the parent class.
Let us look at an example that will make a clearer understanding of encapsulation and inheritance.
