If-Then and If-Then-Else Conditional Statements in Java

If-Then and If-Then-Else Conditional Statements in Java The if-then and if-then-elseconditional statements let a Java program make simple decisions about what to do next. They work in the same logical way as we do when making decisions in real life. For example, when making a plan with a friend, you could say If Mike gets home before 5:00 PM, then well go out for an early dinner. When 5:00 PM arrives, the condition (i.e., Mike is home), which determines whether everyone goes out for an early dinner, will either be true or false. It works exactly the same in Java. The if-then Statement   Lets say part of a program were writing needs to calculate if the purchaser of a ticket is eligible for a childs discount. Anyone under the age of 16 gets a 10% discount on the ticket price. We can let our program make this decision by using an if-then statement: if (age 16) isChild true; In our program, an integer variable called age holds the age of the ticket purchaser. The condition (i.e., is the ticket purchaser under 16) is placed inside the brackets. If this condition is true, then the statement beneath the if statement is executed in this case a boolean variable isChild is set to true. The syntax follows the same pattern every time. The if keyword followed by a condition in brackets, with the statement to execute underneath: if (condition is true) execute this statement The key thing to remember is the condition must equate to a boolean value (i.e., true or false). Often, a Java program needs to execute more than one statement if a condition is true. This is achieved by using a block  (i.e., enclosing the statements in curly brackets): if (age 16)​{ isChild true; discount 10;} This form of the if-then statement is the most commonly used, and its  recommended to use curly brackets even when there is only one statement to execute. It improves the readability of the code and leads to fewer programming mistakes. Without the curly brackets, its easy to overlook the effect of the decision being made or to come back later and add another statement to execute but forget to also add the curly brackets. The if-then-else Statement The if-then statement can be extended to have statements that are executed when the condition is false. The if-then-else statement executes the first set of statements if the condition is true, otherwise, the second set of statements are executed: if (condition) { execute statement(s) if condition is true}else{ execute statement(s) if condition is false} In the ticket program,  lets say we need to make sure the discount is equal to 0 if the ticket purchaser is not a child: if (age 16){ isChild true; discount 10;}else{ discount 0;} The if-then-else statement also allows the nesting of if-then statements. This allows decisions to follow a path of conditions. For example, the ticket program might have several discounts. We might first test to see if the ticket purchaser is a child, then if theyre a pensioner, then if theyre a student and so on: if (age 16){ isChild true; discount 10;}else if (age 65){ isPensioner true; discount 15;}else if (isStudent true){ discount 5;} As you can see, the if-then-else statement pattern just repeats itself. If at any time the condition is true  , then the relevant statements are executed and any conditions beneath are not tested to see whether they are true or false. For example, if the age of the ticket purchaser is 67, then the highlighted statements are executed and the (isStudent true) condition is never tested and the program just continues on. There is something worth noting about the (isStudent true) condition. The condition is written to make it clear that were testing whether isStudent has a value of true, but because it is a boolean variable, we can actually write: else if (isStudent){ discount 5;} If this is confusing, the way to think about it is like this we know a condition is tested to be true or false. For integer variables like age, we have to write an expression that can be evaluated to true or false (e.g., age 12, age 35, etc..). However, boolean variables already evaluate to be true or false. We dont need to write an expression to prove it because if (isStudent) is already saying if isStudent is true... If you want to test that a boolean variable is false, just use the unary operator!. It inverts a boolean value, therefore if (!isStudent) is essentially saying if isStudent is false.

A study on online marketing strategies used by new media entrepreneurs in India. S. Vivin RichardMs. Sri Jothi M. Sc Electronic Media,Lecturer Department of Media Sciences Department of Media Sciences College of Engineering,College of Engineering Anna University, Guindy.

This research helps to understand the nature and extent of business strategies used by successful online Entrepreneurs. Nowadays, most people prefer to get first-hand information from the internet. Being a terrific medium of communication, internet not only helps people to stay informed but gives them a fair idea about the consumer market as well. Hence, it is important to analyze and utilize the power of internet technology in the best possible manner. The need is to analyze and research needs of customers who come online to satisfy their wants. 1. 2. Introduction: Internet is primarily a source of communication, information and entertainment, but increasingly, it also acts as a vehicle for commercial transactions. Since the explosion of the web as a business medium, one of its primary uses has been for marketing. Soon, the web could become a critical distribution channel for the majority of successful enterprises. (Thompson 2002) In online world, companies try their best to make their products much more physically good that actually becomes the possession of life of a customer. The concentration of internet marketing is giving a similar experience to a customer ad help him/her to get the utmost satisfaction. Internet is a large repository of information, ever expanding database and a true knowledge hub. The impact of internet over people has grown over a period of time and people started trusting internet and they bank over the internet for major activities, be it personal, official and business related. Therefore this presents the perfect scenario for the entrepreneurs to market their products across the globe, to a large customer base that their sales force cannot even dream of identifying. Getting on the wings of internet technologies, organizations can easily enhance their overall worth by reaching to new heights of success. Online companies can engage in fruitful marketing activities by using effective new media marketing strategies to boost their product offering in the online market. 1. 1 Online marketing: Advertising in internet provides a major contribution to brand competition in the market. Advertising here not only provides information about a product or service but also promotes innovation. Besides it also facilitates consumer satisfaction. Big and small companies, individuals of all walks of life, major and minor events, concepts, etc. , nowadays lay their base on online marketing to get recognized in the market (Zarrella, 2010). When eBay was started, it was just a hobby, an experiment to see if people could use the Internet to be empowered through access to an efficient market. It was really about helping people connect around a sphere of interest so they could do business. † (Pierre Omidyar, eBay) 1. 2 Aim and Objective * To study the new media marketing strategies used by dotcom Entrepreneurs in India and to determine the most effective practices for the same. To study the dotcom entrepreneurs and their strategies in India. * To analyze the new media marketing strategies used by dotcom entrepreneurs. To identify the different marketing strategies of business enterprises using new media technology. * To determine the effectiveness of new media marketing. 3. Literature Review Scott (2009) states the reasons for brand promoters preferring online web for marketing is that the tools, techniques and content are constantly evolving. The buyers reward creativity by responding to the online efforts like: â€Å"If you are open to trying out new things, you can be first in your industry to use something new to communicate to your buyers†. The rules of marketing had to change and the web has proved a catalyst in bringing the changes forward and amplifying their scale. The sudden emergence of the Web 2. 0 marketing techniques demand additional approaches, while most marketers are still wrestling with the first generation, savvy brands are exploring the landscape that social media and social networks create for marketers. These techniques are allowing much deeper drivers in social change to be unleashed, with a profound impact on planning customer connections. The new generation of relationship marketing responds to the additional challenges of digital media literacy and in the right hands can trigger a rebuild of the entire marketing mix through different strategies. Relationship marketing for the Face book generation demands both thinking and acting differently (Chaffey 2003). Stroud (2007) says that the ability of social networking sites to generate these huge volumes of web traffic is proof of their huge popularity. Google, Yahoo and News International have bought themselves a presence in the social networking arena. The detailed rationale for these acquisitions differs but all have a common theme of wanting access to the enormous audiences. Visitors to online websties as well as social networking sites are significantly more likely than average to visit leisure-oriented retail site categories, such as music, jewelry/luxury goods/ accessories, consumer electronics and apparel. People typically enjoy sharing their experiences with these products, whether it is to talk about their new iPhone or the pair of designer jeans they just bought. Social networking sites offer the venue for those conversations to occur. Online media advertising is ideal for promoting brand recognition. Still, there is no doubt that advertising via online media sites is an effective way to increase your overall revenue stream (Brinlee, 2007). 3. 1 Research Methodology To analyze and find the effective use of online marketing strategy in developing a business online, and to find the effective marketing strategy used online by online Entrepreneurs.

Cmrj 502 - Essay Example They work in partnership with the police forming part of the prosecution that ensures correct charges through elimination of non-viable cases (Cook, et al., 2005). With the help of use of â€Å"threshold test†, the decision on whether a bail or custody is to be executed is determined before charge. The decision on how to carry out the prosecution process is divided into two stages where â€Å"two stage tests† are undertaken. The two tests are carried out in turns by the crown prosecutors. The first stage which is the evidential stage involves the submission of sufficient evidence that must provide a realistic prospect of some conviction. If the case does not go through this stage, the case does not proceed. The public interest is the second stage where the interest of the public is considered. This is because according to lord Shawcross (1951), prosecution has never been automatic since public interest must be satisfied if conviction is to result in a sentence. As part of their role, CPS advises the police on cases for possible prosecution while being guided by the code for prosecutors on how to give timely responses while sticking to their charging standards which aims at restoring the CPS/police arrangements and joined up working (Vines,

The Opportunities and Challenges of Contemporary Public Health Policy Essay

The Opportunities and Challenges of Contemporary Public Health Policy for Specialist Community Public Health Nursing - Essay Example This paper is a critical review of the available literature on specialist community public health policy in England as applicable to health visiting. Some of the more recent position papers along with several research papers on the role of health visiting nurses, their qualifications and skills and the relevant policies will be reviewed. The advantages of health visiting to the target segment and the various challenges faced by health visitors as well the administration will also be discussed to understand the health visiting environment in England. Specialist community health policy in England Despite recognizing the importance of public health promotion and preventative strategies through community settings, public health issues concerning health visiting still remains a subject that attracts much attention. Health visiting may have evolved from simply being concerned with sanitation to addressing maternal and child welfare; it is now being touted as the most essential of services in the realm of public health. Today, health visiting in England and UK as in other countries is being given the importance that it demands. This concept of health visiting primarily focuses on generating awareness among individuals, families and communities as a whole of the importance of ensuring the wellness of both the child and the family (Carr et al, 2012). However, there is an increasing awareness among practitioners and policy makers alike of the need for effective policies and implementation strategies to cater to the demanding and more complex needs of the changing community settings which are more heading towards being multi-ethnic and diverse in nature. There is evidence of a multi-pronged approach to developing health visiting services in England. This can be seen from the initiative by National Health Services (NHS) in gathering evidence base for improving public health based on a three-tier structure that takes in to account the strategic directions set by a board of advisors in collecting the evidence base, dividing the work based on reference group and forming of user panels to establish a framework for evaluation of the evidence base (Bull et al, 2004). The Royal College of Nurisng (RCN), UK’s largest association of nurses, midwives, health visitors and other practitioners has published a position paper on health visiting (â€Å"Pillars of the Community: the RCN UK position on the development of the registered nursing workforce in the community†) which has since been instrumental in contributing to the decision of the Department of Health to endorse the coalition government’s pledge to increase the number of health visitors from 8000 to more than 12000 (an increase by 4200) and also the ‘Health Visitor implementation Plan’ set to guide and strengthen health visiting service in the country, as part of the â€Å"A Call to action: 2011’ publication that endorses a four tier model: Community; Universal; U niversal Plus and Universal Partnership Plus (Health Visiting Services & Public Health Nursing: a consultation document, 2012). Concerns have been raised on the role of health nurses in the community settings where it seemed to take on the role of surveillance more than support to the families of the different communities. However, specialist community

The Harry Potter Controversy Essay -- Fiction Literature Childrens Pap

The Harry Potter Controversy The wildly popular Harry Potter book series by J. K. Rowling has caused controversy for many families over the past five years. These novels according to some critics are harmless, adventurous, children's tales. Others choose to portray them as stories that inspire children to become involved in the occult and serious witchcraft. The Harry Potter novels chronicle the life of a young wizard whose wizard parents were killed by the evil Lord Voldermort. On his eleventh birthday he receives invitation to attend Hogwarts School of Witchcraft and Wizardry. Each of the five books represents a year of his life there (Walker). This essay will discuss whether the Harry Potter novels are a suitable read for children and why despite what some critics portray, Harry Potter can be a positive role model for youth. In recent history a cultural phenomenon has occurred. With the rise of Harry Potter, this nation's youth have displayed a â€Å"mania† that has not been seen in reference to books for a long time. For example, Barns & Noble America's largest bookseller has recently declared that Harry Potter and the Order of the Phoenix will be their â€Å"largest seller in the history of the entire company† (Mangan). In light of this rise to fame one should note that Harry Potter can and will impact modern culture. In the â€Å"age of electronic entertainment†, Harry Potter novels sharply contrast by luring children away from the internet, and away from video games and the television. Children across the globe are rapidly becoming interested in reading the novels. Katherine Thompson, owner of Frugal Frigate Bookstore, declared the series a â€Å"literary phenomena.† She noted that children as young as eight-years-old will devour... ...nuum, 2001.

Concept of Elasticity Essay

Why Economists Use Elasticity Definitions of Elasticity How to Compute the Elasticity of Demand and Supply Examples of Elasticity of Demand and Supply What is an Elasticity? Measurement of the percentage change in one variable that results from a 1% change in another variable. When the price rises by 1%, quantity demanded might fall by 5%. The price elasticity of demand is -5 in this example. Different Types of Elasticities Price elasticity of demand: how sensitive is the quantity demanded to a change in the price of the good. Price elasticity of supply: how sensitive is the quantity supplied to a change in the price of the good. Examples of Demand Elasticities When the price of gasoline rises by 1% the quantity demanded falls by 0. 2%, so gasoline demand is not very price sensitive. Price elasticity of demand is -0. 2 . When the price of gold jewelry rises by 1% the quantity demanded falls by 2. 6%, so jewelry demand is very price sensitive. Price elasticity of demand is -2. . Examples of Supply Elasticities When the price of DaVinci paintings increases by 1% the quantity supplied doesn’t change at all, so the quantity supplied of DaVinci paintings is completely insensitive to the price. Price elasticity of supply is 0. When the price of beef increases by 1% the quantity supplied increases by 5%, so beef supply is very price sensitive. Price elasticity of supply is 5. Why Economists Use Elasticity Economists want to compare apples and oranges all the time. Is oil market demand more price sensitive than wheat demand? no) Is the labor supply of women more wage sensitive than the labor supply of men? (yes) An elasticity is a unit-free measure. By comparing markets using elasticities it does not matter how we measure the price or the quantity in the two markets. Elasticities allow economists to quantify the differences among markets without standardizing the units of measurement. Examples of Unit-free Comparisons Gasoline and jewelry It doesn’t matter that gas is sold by the gallon for about $1. 09 and gold is sold by the ounce for about $290. We compare the demand elasticities of -0. (gas) and -2. 6 (gold jewelry). Gold jewelry demand is more price sensitive. Paintings and meat It doesn’t matter that classical paintings are sold by the canvas for millions of dollars each while beef is sold by the pound for about $1. 50. We compare the supply elasticities of 0 (classical paintings) and 5 (beef). Beef supply is more price sensitive. Inelastic Economic Relations When an elasticity is small (between 0 and 1 in absolute value), we call the relation that it describes inelastic. Inelastic demand means that the quantity demanded is not very sensitive to the price. Inelastic supply means that the quantity supplied is not very sensitive to the price. Elastic Economic Relations When an elasticity is large (greater than 1 in absolute value), we call the relation that it describes elastic. Elastic demand means that the quantity demanded is sensitive to the price. Elastic supply means that the quantity supplied is sensitive to the price. Size of Price Elasticities Inelastic: price elasticity less than 1 Unit elastic: price elasticity equal to 1 Elastic: price elasticity greater than 1.

A Sociological Perspective On The Development, Structure,...

The study of sociology is the â€Å"development, structure, and functioning of human society† (Oxford English Dictionary def. 1). Throughout American history norms established the structure of sexuality that decides what we consider a sexual conformity and deviation in society. Many of these norms are derived from social factors, such as religion, race, and gender to list a few. These social factors affect the functioning of human sexuality. For example, according to Seidman, â€Å"Social factors determine which desires are sexual and which serve as identities, which desires and identities are acceptable, and what forms of sexual intimacy are considered appropriate† (2015:5). The sociological perspectives that are used are the feminist perspective, the essentialist perspective, and the constructionist perspective. First, feminist perspectives â€Å"†¦approach sex as fundamentally social and political where they claim that the very essence of what is called sexuali ty reveals the male wish for control and dominance† (Seidman 2015:22). This perspective is mostly used in the article â€Å"Is Hooking Up Bad for Young Women?†. Second, the essentialist perspective believes â€Å"that sexuality is a basic and essential part of being human† (Seidman 2015:22). This perspective is applied in the Armstrong’s et. al., â€Å"Is Hooking Up Bad for Young Women?†, in Ford, Hall, Kaufman, Thrasher and Whetten’s â€Å"Black Sexuality, Social Construction, and Research Targeting†, and in Fetner’s â€Å"U.S. Attitudes Toward LesbianShow MoreRelatedThe Promise Of Sociology, By Charles Wright Mills1133 Words   |  5 PagesSociology is the study of human social relationships and institutions.
