Object Oriented Programming

Object Oriented Programming There are many definitions in different sources. Some of them are like: Object-oriented programming is a method of programming based on hierarchy of classes, and well-defined and cooperating objects (Oracle, 2010a) Object-Oriented Programming (OOP) is different from procedural programming languages in several ways. Everything in OOP is grouped as objects. OOP, defined in the purest sense, is implemented by sending messages to objects (IBM, 1995a) Object-Oriented Programming (OOP) is a programming language model organized around objects rather than actions and data rather than logic (TechTarget, 2008) So in other words, OOPs is a type of programming in which the programmers have to define not only the data type of a data structure but also the functions or operations to be applied to the data structure. By doing this, the data structure converts to an object including both data and functions. Java, Python, Visual Basic .NET, Ruby, Smalltalk and C++ are among the popular OOP languages. The OOP starts with first step as identification of all the objects to be manipulated and how they identify each other. This is often called as data modelling. Once the object has been identified, we have to label it as objects class and also have to define the type of data contained in it and any logical sequences that can manipulate it. A distinct logic sequence is known as method. An instance of class is called as an object. The object runs in machine (computer). Computer instructions are provided by methods and the data is provided by the object characteristics. OOPs Principles OOP deals with objects, and to define it, w should know the types of objects which are described in class. Objects are instances of class. A class contains methods and attributes. Attributes are used to represent an object by using a dot, like: anObject.someAttribute; the attribute can be any type even same as an object type. Methods are used to represent the working of an object like: anObject.someMethod(parameters); The difference between attribute and method is that an attribute can only contain a value or a state but a method can also do some functioning. In the programming world, there is not any definition of OOP which can be accepted by all at same time but certain principles have been formed to help in understanding OOPs (Filimon, 2007a): Modularity it means to break the program code into different parts which can then easily be interlinked to make a well organized program. Figure 1: Modularity (Filimon, 2007b) Encapsulation it is linked to modularity. According to this, everything except the interface of an object should be hidden and precisely located, so the actual implementation can easily be changed, with an improvement to the program security (Filimon 2007a). Figure 2: Encapsulation (IBM, 1995b) Inheritance this is the main reason in the fine working of OOP. It allows a class to have the same behaviour as another class and extend or remove that behaviour to provide special action for specific needs (IBM, 1995a) Figure 3: Inheritance (Oracle, 2010b) This diagram shows the class hierarchy as it descends from java.lang.Object for the classes in the user interface. Benefits of OOP With the help of inheritance, a programmer can eliminate the redundant code and extends the use of available code. Classes Programs can be built from the working modules which interact with one another, rather than starting the code again from scratch. Due to this, lots of development time is saved and production is higher. Because of data hiding, the programs are designed not be touched by the codes in other parts of the program and this provides greater system security and avoids unintended corruption. Multiple instances of an object can coexist without any interference. Easy to break the work in parts based on objects. Easily small to large systems upgradation of OO systems. With the help of the concept of data classes, a programmer can create any new data type which is not already defined in the language. Code reuse; polymorphism. Errors are caught when compiling rather than at runtime. Works like the way real world works. Easily to map a real world problem to a solution in OO code. Disadvantages of OOP OOP takes more time to execute as it is a high level concept and many routines run at back at the time of execution. Artificial class relations. We can easily make break the program making it more suitable according to us but if the programming is based on real world problem then the modified structure is not similar to what exist in real. Unnecessary complications. Wastage of time in case of small coding programs. Due to inheritance, it is hard to read the code. If u have classes inheriting other classes, then you might end up with code again and again to figure out which method is called. How OOP is used in Software Development? In any complexity of software development, OOP is the best to solve the issue. These are the areas where OOP is used (Buyya et al, 2009): Image processing Pattern recognition Computer assisted concurrent engineering Computer aided design and manufacturing Computer aided teaching Intelligent systems Database management systems Web based applications Distributed computing and applications Component based applications Business process reengineering Enterprise resource planning Data security and management Mobile computing Data warehousing and data mining Parallel computing OOP just helps us to load the real world problem into software which can be modified in different ways depending on the needs. Once a code generated for any software can be used again and again to serve other applications with same functions. This helps in saving lots of time for the programmers and also helps in making the program flexible so that it can be easily modified when there is need. I think OOP is not a successful approach to a beginner in programming because programming is not easy until the programmer does not know what objects or classes are. OOP have many advantages but they will work for the programmers having good knowledge in the concepts of programming. Despite all the advantages, a beginner cannot distinguish between the classes, objects or any other things which makes it difficult to understand. So I think a beginner should start with low level programs to learn the basic concepts and then move to OOP. References Buyya, R., Somasundaram, SS. and Chu, X.

Elements That Influence State Government Essay

According to the Wall Street journal 3 of the top 5 spending political groups in the 2010 midterm election were labor unions. The American Federation of State, County, and Municipal Employees spent 93 million on the 2010 election (The Lonely Conservative, 2012). The New York Times reported that Big Labor spent nearly $450 million in the 2008 election electing Obama and the democrats into office (The Lonely Conservative, 2012) possibly making Big Labor the biggest spender in the 2012 election. The Virginia AFL-CIO is involved in the full spectrum of the political and community issues Virginian face. At the local, county, and state level AFL-CIO has helped make important and beneficial legislation for Virginians. AFL-CIO monitors all legislation affecting the people of Virginia. The AFL-CIO worked to win against laws that would reduce unemployment benefits and lower compensation payments for injured workers who retire (AFL-CIO, 2012). The AFL-CIO’s legislative and political efforts is organizing the strength of working men and women to win good pay, retirement security, safe work environments, and broad access to quality education for their children. By mobilizing through union movement’s state-level and nationwide get-out-the-vote effort, union members elect candidates who support and will enact a working family agenda (AFL-CIO, 2012). In states that have newly appointed republican governors and lawmakers they seems to have an agenda to advance corporate influence and lower wages, suppress voting rights and eliminate worker protection on the job (AFL-CIO, 2012). The AFL-CIO slammed the Republican presidential contenders as being defenders of privilege and opponents of working people. â€Å"Each of the Republican presidential candidates, has pledged to uphold the special privileges of Wall Street and the 1 percent — privileges that have produced historic economic inequality and drowned out the voices of working people in America†(Tau, 3/13). The AFL-CIO indorsed Obama because according to Trumka â€Å"he honors the values of hard work, of mutual respect and of solving problems together—not every person for himself or herself. He believes that together we will get through the most challenging economic crisis in memory and restore opportunity for all,† Trumka also specifically cited Obama’s focus on the insourcing and the revitalization of the American manufacturing sector in the organization’s endorsement. He has worked hard to create good jobs; he has made the revival of the manufacturing sector a hallmark of his jobs agenda; he has moved aggressively to protect workers’ rights, pay and health and safety on the job; he has worked for a fair resolution of the housing crisis; and he put his confidence and administration unequivocally behind the workers and companies in the American auto industry—a move that saved hundreds of thousands of jobs and is helping to revive the economy now and for the future,† The AFL-CIO contributes a lot of money to the democratic campaign because they are in line with the belief of the party. They believe in a quality of life for the workers they represent along with the quality of life for the American people; whereas the Republican Party is for self-preservation. The American citizens that vote for the Democratic Party believe in fair wages, they believe in equality, and family values. The AFL-CIO wants to help achieve the American Dream for working families and they accomplish this through influencing public policies (AFL-CIO, 2012).

The Legacy Of Abraham Lincoln - 1837 Words

Honest Abe Abraham Lincoln was born on February 12th, 1809 in a log cabin in Kentucky. He was raised by poor parents and received less than a year of formal education. He was mainly self-educated by reading a lot of books on his own. Lincoln was known for being an opponent of slavery. He was the 16th president of the United States and served from March 1861 until he was assassinated in April of 1865. His main accomplishments include leading the United States through the Civil War and abolishing slavery. Young Abraham came from humble beginnings and first acquired his nickname ‘Honest Abe’ as a store clerk in New Salem, Illinois. This was all well before he became the president of the United States. A few stories show how he earned this name and why it is well deserved. After shortchanging a customer, Lincoln closed down the shop and walked as far as it took, in this case, 6 miles, to return the coins to the customer. (Leidner) In another instance, a customer bought a half-pound of tea and he accidentally weighed a quarter pound. Again he personally delivered the remainder of the tea to the customer. A local was quoted saying that Lincoln was â€Å"attentive to his business — was kind and considerate to his customers friends and always treated them with great tenderness — kindness honesty.† (Miller, 116) After borrowing a book from a neighbor, it was soaked and ruined by the rain in his cabin in which he left it overnight.
