Java vs C
Java vs. C++ papers = Since their inception, computers have played an increasingly important role in today’s society. Advancements in technology have enabled computers to become faster and cheaper. Today, the majority of families own a home computer that is vastly more powerful than giant mainframes of years gone by. Computer hardware has been evolving rapidly with no end in sight, and with all of the advancements in computer hardware come advancements in computer software; gone are the days when FORTRAN and COBOL were the languages of choice. Today, vvv two hot new object oriented programming languages have entered the computer programming arena, Java and C++, this paper will examine the similarities and differences between these new languages. Both Java and C++ are object oriented programming languages, but what does that mean? Object oriented programming (OOP) emphasizes data, instead of algorithms for solving problems. Instead of trying to fit a problem to the procedural approach of a language, OOP attempts to fit the language to the problem, in other words, OOP is structured to produce an answer without changing the question. Object oriented programming involves two separate parts, class and objects. Class is a specification that describes a new data form, it is a template that defines how an object will look and behave.(Kaj 1996, 8) An object is that particular data structure constructed using the parameters defined by class.(Prata 1995, 5) The object oriented programming approach to program design is to first design classes that accurately represent those things with which the program deals. A drawing program, for example, might define classes to represent rectangles, lines, circles, brushes, pens, and the like. The class definitions, recall, include a descriptions of permissible options for each class, such as moving a circle or rotating a line.(Prata 1995, 5) The main advantages of OOP, besides being able to create more complex software, and develop answers without changing the questions, are numerous. OOP facilitates creating reusable code, which can save a lot of work. Information can be hidden to safeguard data from improper access. Polymorphism lets the programmer create multiple definitions for operators and functions, with the programming context determining which definition is used, also Inheritance lets the programmer derive new classes from older ones.
When using OOP, the programmer can focus on representing concepts, instead of concentrating on tasks. (Prata 1995, 6) Java, although in many respects similar to C++, is actually just a more simplified version of the latter.

Darius had an advantage over Alexander the Great, he had more troops, better resources, and he chose the battle field. Although Darius had the advantage he was not as smart as Alexander. Alexander had good communication with his troops; he planned according, in addition he was well organized before the battled. He did not stray away from his plan he stuck to it. Alexander troops were heavily armed they moved in formation, and they were shield with their long spears they stayed close together and moved in formation. In addition he did not have all his troops engaged in the battle at once he planned an awesome attack strategy that won him and his troops the war.
After the assassination of his father, Philip of Macedon, Alexander took off on a journey that lasted the rest of his life. Taking his inherited army of about 32,000 he set out to conquer all of Persia. Starting with the Battle of River Granicus, he went south along the coast of Asia Minor to Halicarnassus after a year he met King Darius for the first time at Issus where he took his opposer's mother, wife and daughter. Leaving Issus Alexander followed the Mediterranean coastline taking the Island of Tyre on his way into Egypt freeing both those at Jerusalem and in Egypt itself from the religious oppression of the Persian rule. Alexander the Great planed
Few historical figures stand out in the same degree as that of Alexander the Great. He was a warrior by 16, a commander at age 18, and was crowned King of Macedon by the time he was 20 years old. He did things in his lifetime that others could only dream about. Alexander single-handedly changed the nature of the ancient world in just over a decade. There were many attributes that made Alexander “Great.” He was a brilliant strategist and an inspired leader; he led by example and was a conqueror at heart. In looking at his early childhood, accession to the throne, conquests, marriage, and death one can see why Alexander the Great is revered in historical contexts as one of the greatest figures of all time.
These four battles and sieges, out of the twenty battles and sieges that Alexander took part in, were the most important to the expansion of his empire. Without these victories, Alexander would not have been able to expand his empire as much and his existing empire would constantly be threatened by the Persians and their allies. These four battles and sieges further proved the intelligence, cleverness, bravery, astuteness, and graciousness of Alexander, and thus earning him the name Alexander the Great.
To create an outcome that benefits the society in addition to the firm, governments put regulations into place. The externalities of exploiting a resources that produces air are monstrous. In this case, the exchange can cost society lives. Government intervention works to fill the gap of these externalities, to reduce economic freedom in certain circumstances and regulate through appropriate methods like taxation and cap-and-trade programs. In The Lorax, the government should have intervened with regulations that would make the Onceler plant just as many trees as he cut down. This would minimize the deadweight
Alexander the Great did many things for his people who were always supporting and fighting for him. He could not have done this with his great team. With their help, Alexander got to reach and conquer Persia, Egypt, and Asia. On the way to conquering these lands, he was able to defeat some of his enemies such as Darius III. Some things that made Alexander a great leader was that he recognized what was to be necessary and done when others will still in state of uncertainty. He also rose the courage of his soldiers and filled them with hopes and success and dispelling their fear in the midst of danger by his own freedom of fear.
I have important news to tell you today, in which every Greek city-state will be taken to extreme heights of this new era. We have won the Battle of Issus, my friend! Finally, the day has come where we will be able to show Persia, our power and wisdom. Alexander is a key component to our success; we would have never survived without his courage, dedication, and wisdom. Before the war began, he had ridden to the front lines, where he named each solider and reminded us of the permanent values that will follow if we win. Although the Persian army stood before us with massive soldiers and weapons, it was Alexander’s quick reasoning and verdict that allowed us to react swiftly. Alexander’s tactics proved how he can lead and unite the soldiers when faced with difficult opposition.
In order for Alexander to secure the throne, he slayed everyone who could have a conceivable right to the kingship. Although Alexander did not immediately gain power of the Corinthian League, he quickly led his armies to Greece to stop the independence movement from the Greek states. They rapidly accepted Alexander as their leader, giving him infinite military powers to attack Persia, a prodigious kingdom east of Greece. Two years later, after winning battles at Granicus and Issus, conquering Tyre, and then wintering in Egypt, Alexander’s army finally met the Persian’s army for the first time (Kurke 71). Alexander's assets were inferior to those of Darius III, the king of Persia at the time, but managed to defeat the Persians and keep moving deeper into the kingdom. This was the ignition to the Battle at Gaugamela, perhaps the most important battle of Alexander’s young life as a king. Writer of Wisdom of Alexander the Great, Lance Kurke noted, “How, you might ask, can destroying an army build alliances? The Greek and Persian cultures could not be merged while a Persian army could be fielded. Sometimes you have to destroy to build” (71). That was the mentality of Alexander the Great, he used his power to his full
The war of Agis III in 331 BCE demonstrated that a war that should have been easily won was not; however, it was won in the end. Alexander also bought the loyalty of his troops with high pay, bonuses, remission of taxes, cancellation of debts, and signs of royal favor. Even with these benefits, his troops weren’t always loyal to him and sometimes mutinied. They mutinied once in 326 BCE and refused to keep marching, forcing Alexander to turn around and head back. He also risked the lives of his men. While heading back, Alexander took a different route through the Gedrosian desert, resulting in starvation, heat, dehydration, and the slaughter of baggage animals. By taking this route, he unnecessarily cost many of his troop’s lives. He also endangered lives during the unnecessary siege of Tyre in 332 BCE. In addition to his own troops that died, he killed all the men of Tyre. Another reason Alexander didn’t deserve the title of ‘Great’ was that he murdered his friends and people that disagreed with him. For example, he had Philotas and his father killed because they didn’t support his policies and strategies. While Alexander was a brilliant militarist, he didn’t rule his conquered territories. He was more concerned with conquering than with ruling what he had already conquered. He ruled
At the age of 16 his father Phillip left him in charge of Macedonia while he was away battling the Byzantium's. In 338 B.C.while Phillip the 2nd was still away at war Alexander without his father's permission lead a cavalry against the Sacred Band of Thebes. He did this in an effort to prove himself in which rightfully he did so by decimating the army, he did this at the age of 18,this is what would come influence to further his military expeditions through the rest of his life. In 336 B.C. when Alexander ascended to the throne he was just 20 years old. As he claimed his throne he crushed many rebellions throughout greece once even destroying the entire city of Thebes just to prove a
As is suggestive of its name, an operating system (OS) is a collection of programs that operate the personal computer (PC). Its primary purpose is to support programs that actually do the work one is interested in, and to allow competing programs to share the resources of the computer. However, the OS also controls the inner workings of the computer, acting as a traffic manager which controls the flow of data through the system and initiates the starting and stopping processes, and as a means through which software can access the hardware and system software. In addition, it provides routines for device control, provides for the management, scheduling and interaction of tasks, and maintains system integrity. It also provides a facility called the user interface which issues commands to the system software. Utilities are provided for managing files and documents created by users, development of programs and software, communicating between users with other computer systems and managing user requirements for programs, storage space and priority. There are a number of different types of operating systems with varying degrees of complexity. A system such as DOS can be relatively simple and minimalistic, while others, like UNIX, can be somewhat more complicated. Some systems run only a single process at a time (DOS), while other systems run multiple processes at once (UNIX). In reality, it is not possible for a single processor to run multiple processes simultaneously. The processor of the computer runs one process for a short period of time, then is switched to the next process and so on. As the processor executes millions of instructions per second, this gives the appearance of many processes r...
After my twelfth grade, the inherent ardor I held for Computer Sciencemotivated me to do a bachelors degree in Information Technology. Programming and Math, a paragon of logic and reasoning have always been my favorite subjects since childhood. I still vividly remember the time during my graduation,when I was successful in creating a simple calculator application as a class assignment.The joy I derived from creating something that is used by a lot of people to help them perform complex calculations,made me realize the power of computing in its true sense.It was also in my graduation that I developed an immense interest in programming languages such as Java, C++ an...
How do you feel when you drive by some sort of factory or plant and you see an obnoxiously large smoke stack spewing fumes into the air or a drainage pipe of chemical runoff that flows into a water supply? The sense of disgust from the thought of how these companies get away with this action not only concur with opinion of environment activists but also involves the United States government. It was not long ago that the government realized that these effects were harmful to the world around us, which caused the government to create several groups to enforce laws and regulations against these unethical operating businesses. These questions are similar to those frequently asked by many economists when discussing the subject of business environmental laws and ethics. A business must decide how they want to run their business, unethically by cutting corners or abiding by ethical and law standards. This issue comes down to the standpoint wherever businesses may fall on if they care more about using unethical ways to gain some sort of advantage or if they would rather operate in a way with limits but complies with ethical and law standards.
