Essay On Java

Essay on Java
Java is one of many high–level programming languages that use abstraction (reducing and factoring details) to create software for computers and many
other electronic devices. Compared to low–level programming languages, high–level programming languages use a mixture of natural language (any
language used by humans) and typical computer terms to create an easier to understand and simpler form of programming. Figures 1 and 2 show the
difference in writing a simple program called "Hello World" in Assembly (a low–level programming language) and in Java.
Like human languages, programming languages have different levels of writing difficulty; some are easy to write, while others require extensive
computer knowledge to understand. In...show more content...
There are three parts in a Java program that are essential for a program to run. In every Java application, the code always starts with a class (where
instructions are written) definition. In the class there is a main method that passes specific requirement into the program. Finally, other methods other
than a main that act as functions are written to do specific tasks that the program requires. Three parts of Java
As mentioned earlier Java consists of many different parts, but, there are three that are usually the most important in Java. They are; classes, methods
and objects. Classes are a blue print to creating objects that are used in the program. Methods are Java statements that must be in a class, for a Java
program to work, it has to have at least the "main ()" method. Finally, objects store current states and also show their behavior when called through a
method.
How a Java program works
Java is usually written in an Independent Development Environments (IDEs). IDEs are programs that have all the resources of writing a program in
one place. Unlike C++, a language that is similar to Java, programs written in Java can be used in any operating system that can run Java Virtual
Machine. This makes Java one of the most versatile and widely used languages for commercial software programs and other fields. The process of

Essay On Software Development
Software Development has evolved immensely over the past few decades and especially in the past few years. We have seen an increase in the
demand for software across all platforms. Electronic device usage is growing worldwide and every one of those devices requires software whether it
has a user interface or not. Think about the transportation industry, semi–autonomous vehicles are offered by many different auto makers with more
and more of them announcing their plans to automate driving each year. The software that runs this aspect of the vehicle only has a small user
interface footprint but the requirement for software development perfection has exponential consequences. This is becoming the norm in our everyday
lives. More and more...show more content...
Since the method was developed for manufacturing and construction projects, it made sense in these industries that a portion of the project was fixed
and unchangeable after a phase completed. Imagine the construction of a road, you prep and lay down a foundation then eventually lay down the
final asphalt or concrete layer. It wouldn't make sense to build in the ability to go back and change the foundation after the top layer was set.
Obviously, software engineering is very different and therefore requires a much different approach to development. Besides slow turnaround, there
were many other criticisms of the waterfall method. Some included redesign, rework, and retesting due to lack of knowledge about requirements when
a project began. Also, due to the extremely long lead and delivery times, requirements changed or projects were dropped altogether leaving a company
with a half–built loss on the balance sheet. An industry average put the estimated time for any software project using the Waterfall approach at 3 years.
This was the environment that enabled a few forward–thinking developers to meet and design a new and better approach. They met first in 2000 but it
wasn't until the winter of 2001 that they delivered their Agile framework to the software community. A manifesto was written that outlines the Agile
framework

Software Testing Techniques

Discussion: Introduction:
Software project management is necessary to develop a high quality software product. Software project management involves the activities of
planning, organizing, directing, monitoring and controlling. We are concerned with the risk factors which will affect the management activities and
the developing project will not proceed according to the plan. The term "Risk" is a problem which can threaten the success of the software project.
But we often assume that everything will go exactly, it is planned [1]. A challenge for IT industry is to develop software system that meets business
needs. The fact is we have to deliver software that is free of bugs. The bugs in software can cause major loss in IT organization if they are not removed
before delivery. Software testing is as old as the hills in the history of digital computers. The testing of software is an important means of assessing the
software to determine its quality. Since testing typically consumes 40 – 50% of development efforts, and consumes more effort for systems that require
higher levels of reliability, it is a significant part of the software engineering. Software testing is performed to support quality assurance [2].Good
quality software can be made by using an efficient test method. Statistics say that 50% of the total cost of software development is devoted to software
testing even it is more in

According to CareerOneStop, about ten percent of software developers either have no college degrees, or only have high school diplomas. The
creative aspect generated behind computer programs are made by software developers. Some develop the virtual systems that run society's gadgets or
control networks. Other software developers make applications that enable people to perform certain tasks on a device. If someone wanted to be a
software developer, they have to have expertise in computers and electronics, engineering and technology, mathematics, telecommunications, and
design. They would also have to perform tasks such as developing and modifying software to meet user's needs, making sure that the software runs

Some collages that are revered and offer computer science degrees are Massachusetts Institute of Technology (MIT) in the city of Cambridge, Harvard
University in Cambridge, Massachusetts, and Stanford University in Stanford, California.
Although knowing what degrees are needed to become a software developer and the colleges to go to are important, one of the main things someone
would need to know to be a software developer would be the skills required. One skill that is required is reading comprehension. This is vital to
becoming a software developer because computer programmers (software developers) must be able to comprehend other programmer's code as well as
other work related events involving literature. Another skill required is critical thinking. This is a required skill because software developers need
to use critical thinking to solve problems and bugs. An ability needed to become a software developer is deductive reasoning. Deductive reasoning is
required because it allows the person to use general rules to solve problems both inside, and outside the code. All of these skills and abilities would
help someone become a software developer and succeed in the industry.
Knowing the skills and abilities to become a software developer is definitely needed, but typically someone would want to know the salary and
demand for this occupation. First off, the demand for software developers is growing as the

Open Source Software Essay
Open Source Software Ever since computer programmers began collaborating online to build software applications, the "open source" movement has
been developing into a serious rival to the multinational software companies. Since the term was coined in the late 90s, open source has rapidly matured
from an egalitarian approach to software design into a movement whose practices underpin the internet. More recently, it has begun to represent the
seed of an ideology, whose approach to openness and sharing is spilling over into the wider world.
The term open source is used...show more content...
At IBM, the next generation of computer chips is being designed using the same open methods that have revolutionized software. Claims are even being
made that anything from marketing techniques to drugs, beer to washing–up liquid, can in some ways be described as open source.

Open source ideas are breaching the boundary between software and electronics. The next generation of computer chips is being designed using the
same methods that revolutionized software.
––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––
The main problem with transposing open source ideas on to the physical world is that it involves more than a simple matter of replication. As Richard
Stallman В— the Martin Luther of the open source movement В— once pointed out: "You can't download hardware through the net, and we don't have
automatic copiers for hardware".
Even so, while hardware or machinery might be relatively expensive to reproduce, designs for them are not. Blueprints for computer chips or formulae
for life–saving drugs can be reproduced just as cheaply В— and distributed just as easily В— as computer code.
So many non–software open source ideas abound that earlier this year, the thinktank Demos warned that overuse of the term threatened to muddy the
waters. The authors of Wide Open, a provocative pamphlet emphasizing how open source ideas were spilling

One of the skills that a Software Engineer needs is to have good communication. If a Software Engineer does not have good communication skills,
how are they supposed to communicate with your boss, or talk to other engineers about a large project that is due (Career Focus 2)? Another skill
Software Engineers need to have experience in programming, without this skill, Software Engineering is basically useless. Having experience in
programming is a skill that Software Engineers need to know because this is the skill that will help an engineer build programs (Career Focus 2).
Software Engineers need to be product oriented people, being product oriented is important because without this skill engineers won't get anything
done, they will be focused on other things when they need to be focused on their task is (Career Focus 2). Software Engineers need to have
knowledge of different programming languages, different languages do different things and if an engineer only knows one of many different
languages then they will be limited on the work that they are assigned (CUnet 2). The most important skill a Software Engineer needs to have is to
keep up with changing technology; if a software engineer can not keep up with the rapidly changing technology they are going to be limited on what

Are educators programmed in the same fashion? Do schools exist as mere training for economic production? More important, is it peculiar the premier
word–processing software for secondary education students, academic instructors and corporate professionals is indeed the same product? I find it
hard to believe that business software fits the needs of high–school students adequately. A call to action for teachers employed at the secondary level is
essential to lobby for the creation of more practical word–processing software, which could enhance basic writing comprehension.
Let's face it; advertising is as American as apple pie. At present, we're programmed incorrectly by marketing campaigns to believe that SUV vehicles
can champion almost any weather condition. Jeep's trademark commercial includes the Grand Cherokee driving up a mountain. In the same respect, via
perception, students are led to believe that computer software can transform writing into perfectly constructed essays by clicking a few commands.
Grammar, spelling and text editing are common features in any word–processing program and I've never seen a disclosure warning users about product
limitations.
Historically, word processors were developed with businesses in mind. Somehow, in a rush to support the Clinton campaign to give a child in every

All jobs need some sort of qualifications to work at that specific job. As a programmer, the person may not go very far if they only have a high
school degree. Most employers require programmers to have at least a bachelor's degree (Education Portal). Some higher–ranking jobs may even
require a master's degree (Education Portal). Some qualifications may be as simple as having a certain amount of experience (Education Portal). With
an advanced degree and certain knowledge, a programmer could become a software engineer (Education Portal). Certain employers and jobs may want
the programmer to have great technical skills, and programming needs in the businesses (Education Portal).
Other than going to school and getting a degree, employers may want more experience and more skills then the programmer may have. During
college the programmer most likely spent an abundant amount of time programming for class and maybe some of their own projects. The
programmer may get an internship and be supervised so they will eventually get the experience they need (Education Portal). Later down the road in
life they my need more experience to get a higher up job. Experience and maybe more

2.3. The difference between system software and application software System software consists of programs that run in the background, enabling
applications to work smoothly. These programs include assemblers, compilers, file management tools, and the operating system itself.
While system software is automatically installed with the operating system, you can choose which application you want to install.
Application software is different from system software or middleware, which is involved in integrating a computer various capabilities, but typically
does not directly apply to the performance of tasks. The purpose of system software is to insulate the application program as much as possible from the

details of the particular computer complex, especially memory and other hardware features. Such accessory devices are communications, printers,
readers, displays, keyboards, etc. Application software is often purchased separately from computer hardware. Sometimes applications are bundled with
the computer but they always run as independent applications, since they are often tailored for specific platforms. The separate applications in a suite
usually have many common user interfaces which make it easier to learn

Use Of Software As A Service Essay
Introduction The technology of software as a service has been around for a long time and has been used in some form ever since its development.
Consequently, the applications associated with software as a service can take many forms and assist users in accomplishing many tasks. The
huge thing in today's market is the ability of running software over the internet and then being able to access the software via an internet browser,
from anywhere the user may be. This ability, while not really new, is more common now and used by more and more businesses and individuals
as an everyday tool.The convenience factor of this type of service has both positive and negative connotations but due to its wide usage and
growing popularity it is very possible that software as a service is going to truly control the information management systems for several years to
come. This paper will discuss the use of software as a service (SaaS)and why this type of service is growing more and more popular today, and why
it will dominate the information management for some more years. Understanding the Cloud In order to fully understand what software as a service is
and how it can benefit the user you must first have an understanding of how this type of computing is accomplished. I think it is important to
understand what is meant by the "Cloud". Cloud computing or software as a service, put simply is when software is ran over the Internet and accessed
by an Internet browser (Schneier, 2009).

Different Types Of Software Types And Their Uses
Digital Technologies 1.40
In this report I am talking about a number of different software types and their uses. There are many types of software that all do different jobs.
There are also many brands or different alternatives to certain software's such as .png (portable network graphic) and .jpg. there are other types of
software that do not preform one specific task but instead allow other software to run. These are operating systems these allow higher level more
specialised software to run while doing the base computing to make it easier on the components of the computer. And also communicate with the
components.
Operating Systems and Application Software
When computers started out, customised programs used to be written and run at a very primitive level. This involved manipulation of bits and bytes
using numeric instructions called "machine code". Eventually, symbolic languages were developed that made this manipulation easier. However, as
computers became more complex, it seemed senseless for each program to repeat the same code that handled "low level" tasks like reading and writing
to disk, altering graphical displays, and printing information. Things became even more tricky when multiple users needed to be accommodated.
These low–level tasks are all now handled by the operating system, which acts as an intermediary between the "higher level" programs that
accommodate users, and the lower level tasks of system management already mentioned above–memory

Engineering Software For Safety Critical Systems
Engineering software for safety critical systems can be a tough task. In all respects, it should be. The Therac–25 incidents are only examples of
scenarios in which the development of safety critical software can go awry. Another example of a safety critical system might be the software that
runs a nuclear power plant. Still other examples might be the fly by wire system in an avionics deployment, or the electronic parking break in an
automobile. The failure of these systems can spell disaster to human life. As such, additional measures must be taken in the development of software
that, if it fails, can cause loss of, or even damage to, human life. As our text tells us, safety critical software must undergo a development and testing
process that is much more rigorous and time consuming than the processes used in the development and testing of other types of software. The system
must be coded carefully, inspected, documented, tested, verified, and analyzed. There must be a product safety engineer assigned to the system, a
hazard log implemented and risk analysis performed as core developmental processes. (Reynolds 276) The software development process should not be
carried out by a single software engineer, but rather by a properly organized team that can audit, and if needed, correct one another 's work. (Reynolds
276) Also, engineers should not place too much trust and confidence in safety critical software. Doing so is one of the factors that led to the failures
