“During the object-oriented analysis (OOA) phase object-modeling techniques are used to analyze the functional requirements for a system and create models which reflect the logical design of the system. During the object-oriented design (OOD) phase of the system, models are elaborated upon to include implementation specific details that show how the physical design of the system will come together. OOA focuses on what the system does (its static structure and behavior), OOD on how the system does it (its run-time implementation).”
Algorithms are set of steps for solving a problem; algorithms also make the program faster. For example, when you are checkers games and you want the user to be able to play against the computer. Computer scientist must figure how to a checkers’ program that never loses by using the minimax search algorithm to search through the huge tree of possible moves. Another interesting topic that I learned in the video is object code. Object code is the output of a compiler after processes source code; source code was written by a human in a programming language for a computer program. A compiler is a conversion of source code into object code. Object code is usually a CPU, but sometimes it designed to convert source code into an assembly language or into some other programming
In Object-orientated approach methodology, a system is viewed as an object (Govardhan & Munassa: 71). This approach intergrades data and processes into objects. It emphasizes the construction and testing of object models. This technique uses UML diagrams such as Communication Diagrams, which show the relationship between objects, Development Diagrams which show how a complete system will be deployed on one or more machines, the Class Diagram and Sequence Diagram.
OOPLs have been around since the 1960’s (Deitel, Java How to Program). They handle tasks by viewing them as a group of different objects. Objects are created from a class which could be considered the blueprint. Objects contain data stored in fields, and the procedures which manipulate the data are known as methods. These objects can interact with each other. There are some key elements of OOPLs, such as code reusability. In OOPLs, through what is known as inheritance, code can be reused. Think of a cup, it is an object. It contains a liquid and overflows when it’s full. If you wanted to program a coffee mug, wine glass, or sports bottle, you could reuse the code for a cup though inheritance, then add extra fields
Object-oriented programming at its core is a practice of strategic thinking. Essentially, in OOP we tend to focus on objects rather than "actions" and data rather than logic. A key step in OOP is identifying the objects one wants to manipulate and observing how they relate to each other. The basic idea of OOP involves breaking up the code into objects that can message each other, which proves to be very beneficial. To better understand and use object-oriented programming as intended, I decided to investigate two different languages that implement the object-oriented approach to programming. I chose Java because I am already familiar with the syntax and its
Procedural programming uses a list of instruction to tell the computer what to do step by step. It relies on procedures, routines and sub-routine. The procedural contents of capitation of steps to be carry
Object-oriented programming (OOP) and procedural programming are two programming paradigms. Procedural programming is a method of writing software. It is a programming practice centered on the procedures or actions that take place in a program. Object-oriented programming centers on the object. Object-oriented programming creates objects from abstract data types that encapsulate data and functions together (Gaddis 2010). There are many similarities
Object-oriented programming language is a high-level programming language based on the object. Data hiding, Inheritance, and polymorphism such basic features of this programming languages. this method is not used for computer programming Until the early 1990s. But, mostly use this language for modern computer programming.
The focus of object-oriented view is on the elaboration of design classes that belong to both problem and infrastructure domains. Classes are elaborated by specifying messaging details, identifying interfaces, defining attribute data structures, and describing process flow for operations. In traditional view, three components are refined, they are control modules, domain modules, and infrastructure modules. To generate programming language source code detailed representations of data structures, interfaces and algorithms for each program are to be created.
Getting information to the reader on computers and computer programming is the purpose of this essay, so there is no need to cover what one would need to know, as it will be explained. It is a crime that the people who have worked to create computers, and programming today have little to no place in the current history books. Although there has been the occasional movie such as The Imitation Game for the most part the history of computer programming has been criminally under reported. For some people like Jim Daniels a computer engineer and teacher at
After the organized philosophies, programming improvement methodologies developed into Object-Oriented (OO) approachs. They incorporate the
This is a very important step in any programming job. We have to get the requirements needed and to be highly considered while constructing the program. The following are very vital and useful information gathered from the assignment text.
Object-oriented approach was developed in late 1950’s in MIT to overcome the drawbacks of procedural- oriented approach. Ii is commonly known as OOPS. Now, it has become most preferred programming approach by software engineers to solve real world complex problems. The traditional procedural languages solve problems in terms of the structure of the computer i.e. memory bits and bytes, array, decision, loop rather than thinking in terms of the problem which is to be solved.
First of all, let me begin with Object oriented programming. Object oriented programming is a type of a computer programming language in which begin with the basic concept of an object. Where to object is characterized by its states and behavior. The state is basically information about object known about itself and behavior is an action that object can do or react. For example, if you meet a new person the state is a name, address, height, weight, and so on and its behavior of a person can be speaking, read, write, run, walk, swim, jump, and so on. Objects are
Object-oriented programming (OOP) and object-oriented design (OOD) refer to a particular way of organizing programs, one which is rapidly emerging as the preferred approach for building complex software systems (Morelli, R, 2000 pg. 5). Sommerville (2001) gave the following definitions:
