Java Syntax Converting Strings to Numbers

Typically in a graphical user interface, there will be text fields that are expecting the user to enter in a numerical value. This number value will end up in a String object which doesnt really help your program if you want to do some arithmetic. Fortunately, there are wrapper classes that provide methods for converting those String values into numbers and the String class has a method to convert them back again. Wrapper Classes The primitive data types that deal with numbers (i.e, byte, int, double, float, long, and short) all have class equivalents. These classes are known as wrapper classes as they take a primitive data type, and surround it with the functionality of a class. For example, the Double class will have a double value as its data and provide methods for manipulating that value. All of these wrapper classes have a method called valueOf. This method takes a String as an argument and returns an instance of the wrapper class. For example, lets say we have a String with the value of ten: String number 10; Having this number as a String is no use to us so we use the Integer class to convert it into an Integer object: Integer convertedNumber Integer.valueOf(number); Now the number can be used as a number and not a String: convertedNumber convertedNumber 20; You can also make the conversion go straight to a primitive data type: int convertedNumber Integer.valueOf(number).intValue(); For other primitive data types, you just slot in the correct wrapper class—Byte, Integer, Double, Float, Long Short. Note: You must make sure the String can be parsed into the appropriate data type. If it cant you will end up with a runtime error. For example, trying to covert ten into an integer: String number ten;int convertedNumber Integer.valueOf(number).intValue(); will produce a NumberFormatException because the compiler has no idea ten is supposed to be 10. More subtly the same error will occur if you forget that an int can only hold whole numbers: String number 10.5;int convertedNumber Integer.valueOf(number).intValue(); The compiler wont truncate the number it will just think that it doesnt fit into an int and that its time to throw a NumberFormatException. Converting Numbers to Strings To make a number into a String follows the same sort of pattern as the String class has a valueOf method too. It can take any of the primitive data type numbers as an argument and produce a String: int numberTwenty 20; String converted String.valueOf(numberTwenty); which puts 20 as the String value of co nverted. or you can use the toString method of any of the wrapper classes: String converted Integer.toString(numberTwenty); The toString method is common to all object types—most of the time it is just a description of the object. For wrapper classes, this description is the actual value they contain. In this direction, the conversion is a bit more robust. If the Double class was to be used instead of the Integer: String converted Double.toString(numberTwenty); the result would not cause a runtime error. The converted variable would contain the String 20.0. There is also a more subtle way to convert numbers when you are concatenating Strings. If a String was to be built like: String aboutDog My dog is numberTwenty years old.; the conversion of the int numberTwenty is automatically done.

Best Administrative Practices Involving Liability - 975 Words

Best Administrative Practices Involving Liability Become familiar with the school’s emergency/health procedures in order to improve teachers’ responses to student injury. To avoid liability teachers must employ a standard of care with is equivalent to that of a â€Å"reasonable and prudent person† (LaMorte, 2012, p.327). LaMorte (2012), further indicated that this standard will be influenced by the â€Å"age of student, mental capacity, environment and circumstance of injury† (p.327). For instance, you would not leave a kindergarten class unattended with scissors. Despite teacher’s best efforts accidents may still occur, therefore, it is increasingly important to have clear and practical emergency procedures. It can be beneficial to create a school-wide emergency response team to insure that the student’s injuries are minimized in an event of bodily injury. Finally, teachers should be trained on the appropriate technologies in order to accurately report classroom incidents. Clearly communicate the expected time of school arrival and departure to parents as an effort to maintain a reasonable degree of student supervision. LaMorte indicated that schools are placed under â€Å"a general duty to supervise the conduct of children on school grounds during school sessions, school activities, recess and lunch periods† (LaMorte, 2012, p.330). Student arrival by bus can be considered the beginning of the school day, therefore, teachers or support staff must be present at that time.

The American West Free Essays

I believe this cartoon was published in the early 1840’s to persuade people to not become Mormons. The Mormons were unpopular during the 1840’s as they had different beliefs to the rest of the settlers. They believed they had found the second part to the bible in America, no one really considered the Mormons a serious religion until Joseph Smith set up a church. We will write a custom essay sample on The American West or any similar topic only for you Order Now People were often jealous of the Mormons as the Mormons believed in working hard to obtain success and money. Mormons also followed polygamy like the Native Americans, people disrespected them because of this and as the picture shows the man hiding from his many wives, who are fighting and the children, which are crying on the floor. I believe this cartoon was published in the early 1840’s to persuade people to not become Mormons. The cartoon shows an un-ideal life as everyone is making chaos, this would deter people from becoming Mormons as it shows people what is supposed to go on inside the Mormon life. Because people hated the Mormons for whatever reason, the man is put across as a coward as he is hiding away from what is happening. This cartoon was probably used to create a general impression of the Mormons. I think the Mormons were able to complete their journey across the Great Plains and into the Rockies from what I am shown in the source as the Mormon’s seem to be well supplied and travelling in large groups. You can tell that the Mormon’s were well supplied and organised because they built log houses to keep warm and safe during the winter, we can also assume that the journey was taking them a long time as the log houses are permanent building which would not have been easy to build or move. I don’t think the Mormon population suffered that badly during the crossing despite losing 700 people to illness or starvation as due to polygamy there was a lot of children who would grow up to continue the Mormon faith. I think so many people died because of starvation because in the photo there is no evidence of food or any sources of food. The source shows us a scene in which the Mormons seem to be doing quite well as the have shelter, protection and transport as well as this because the Mormons were friendly with the Native Americans they didn’t have the fear of raids. Source C tells us that some Mormons didn’t find Salt Lake as impressive as they first assumed. They said that the land was beautiful, but there were no resources for building and they were relying on the land to be fertile, otherwise they would have no food. Some of the Mormons would think of ideas that could work, they would then work hard to achieve them as this is what they believed in. Some of the Mormons will have seen prospect in the land and others will have tried to make the most out of what they could see, ‘There is little prospect for log houses, but we can make Spanish bricks’, from the journal of William Clayton from the Mormon Pioneer Band which reached Salt Lake first. I believe that the Mormons were disappointed in the appearance of Salt Lake. However they also believed that there was prospect in the land and surrounding area, so they made the most of what they had and since the rest of the settlers hated them they could start a purely Mormon society.

Generational Diversity and Its Impact on Organizational Development St

Question: Discuss about theGenerational Diversity and Its Impact on Organizational Development Strategy. Answer: Introduction The workplace is continuously becoming more varied and poses more trials for the human resource managers of today. Misunderstandings are becoming a common occurrence among generational workers, it has become more problematic and still growing. This is because of a difference in work value amongst the different generations. Managing this miscellany in the workplace requires that the Human resource managers comprehend and relate effectually with people who are different from themselves. The ability of personnel to build harmony and strength through their diversity is the muscle propelling these institutions into new magnitudes of performance.(Notter, 2009) Deliberations of office diversity in countries such as the United States tend to commence on topics such as race, sexuality, gender, ethnicity and disability. Establishments that desire to flourish in the future necessitates having a workforce and leaders who are mindful of and experienced enough to deal with the differences along the said identity lines. Another important diversity that is usually overlooked is the generational difference which is the main point of focus. In a majority of large institutions, you are likely to find units, work teams, and divisions, where at least distinctive age group is functioning side by side. Researchers have recognized vital variances amid these generations in the way they approach everyday jobs at the workplace, employee allegiance, and authority(Sweetman, 2004). In the older days, many generations while employed in the same organization were apart from each other due to the nature of their job descriptions, and the groups ranking. Currently, four generations exist at the workplace. These four generations work side by side leading to the occurrence of glitches due to the difference in the ages. Workers from the same generations share work ideals, these ideals commonly differ for a different generation to generation. This includes opinions concerning leadership, authority, and goals at the workplace. A generation refers to a set of individuals who are defined by their age limits. People born in a given period. These people share related familiarities growing up, and their ethics and approaches, especially towards work related ventures tend to be alike(Debra Dupree, 2009). This is by their collective experience during their formative years. This is because of the variations within the generations is enormous. The general features of each age group prove to be valuable in the management of the multiplicity at the workplace; this is because it helps people comprehend their own and others expectations about how establishments should operate and how individuals should treat each other. The Cohort theory states that interests are evident in the effect of generational dissimilarities in the workplace. Work beliefs may vary hence impacting a related age at a point in time(Parry, 2014). Todays workforce comprises of four generations. Matures, the Boomers, Generation x and the Millennials. The Matures This is the generation that was conceived before the commencement of the World War two. Many still have memories of the Great Depression. Many of these individuals have already retired, and this category of workers account for only approximately 5 percent of the workforce currently. An important factor to know is that even though the individuals in this group account for only 5 percent of the workforce, they are in high-ranking positions and exercise substantial power. They are highly swayed by family and conviction; this generation view education as a dream and holiday time are taken to be a compensation for hard work(Underwood, 2007). Many are not comfortable with change and focus on being stable. This generation is characterized by the values such as dedication, hard work, sacrifice, conformity, respect for the authorities and law and order. Boomers This generation consists of those individuals born between 1940 to1960s. The group grew up through a time of fortune (in the 50s), then twisted into the time of social turmoil (in the 60s and 70s). Currently, this group comprises of those aged between forty and sixty years old. This category of individuals account for 45 percent of the labor force; they are more than any other known generation. They are referred to as the generation of the self-absorbed,' flaunting the individuals capability of accomplishing whatever he/she sets out to achieve. The generation practices their parent's hard work beliefs more to the people benefit rather than the companys interest. The generation of this era experienced an evolution in the solidity of the household. However, education was taken to be a right rather than a dream. The important values that are attributed to this generation include team alignment, optimism, personal fulfillment, personal growth and development, involvement, youth and work( Johnson Johnson, 2010). Generation The beginning of this age bracket into the labor force coincides with the identification of the dissimilarities in generations in the workplace. Early in the 1990s, some articles were being written which were describing the emerging force as it moved to employment at that time, with some doubt and frustration. This generation comprises of individuals born between the 1960s and 1980s. Currently, this generation is aged between 20 to 40 years. This number is slightly lower than that of the boomers. They account for only 40 percent of employment. The generation entered the labor force after the first wave corporate downscaling, their approach to the workplace lacked loyalty, and the individuals had a strong entrepreneurial soul(Potter, 2015). Millennials This is the newest entrants in the workforce. Born after 1980, these individuals are more than 22 years of age and occupy only 10 percent of the workforce. In this generation leisure is also a part of their work life. These individual are flexible and are more contented with variety. This is the internet generation, raised around PCs. They value achievement and are very social and confident(Mehta, 2009). The impact of generational diversity on organizational development strategy Range, as a subcategory of corporate growth, continues to achieve substantial status, especially in the last 15 years. Identification of generational Metamorphoses has just of late come to the forefront as a vital issue for crafting a well organizational vibrant. Therefore, this is a new edge for corporate improvement approach and offers untapped opportunities(Matthew Legas, 2011). Flexibility in the administrative arrangement is a vital constituent for taking on generational diversities. New organizational development agendas and strategies will have to advance to reflect this necessity. Like in most theories, it will be subservient for executives to take into account the wishes of the modern business environment and employees. It is likely to prove fascinating in comparing the various emerging diversities in the workplace(Geisman, 2005). The indication is to make it conceivable for the individuals within a particular organization to be able collaboratively to succeed the ethos of that setting in a manner that the goals and purposes of the establishment are achieved, and at the same time, social values of people within the institution are furthered. Individuals in the workplace are also urged to be self-aware, this creates the baseline from which people in the organization work(Rood, 2010). People first need to apprehend their filters in which their needs and morals are entrenched. The individuals then will need to comprehend the needs and values of other generations in common. Generational variance is a lens through which the common behavioral trends and practices in the organization are observed. Specifically, communication styles, ethics of work, management style, interactions, and the workplace enterprise. All these are influenced by the culture of the establishment. Therefore, an application of the empathetic of how these are subjective by generational values backs the foundation of effective intermediation formulas in the institution(Kister, 2012). The critical issue that diversity deals within current organizations is difficult for some even to visualize and consider. The ability of an organization to make good use of a mixture of human and additional resources to create a unique blend of focused policy results, by its nature, develops an inventive progression thats hard to copy. This creates a competitive benefit which is obscure to other competitors. A business that makes use of this generational diversity as a strategy keeps its competitive edge sharp for a long time making the generational difference the primary source for workable, economic potential. Summary While applying strategies to effectively face the generational differences, it is imperative that one ensures that the performance prospects remain persistent to eradicate the presence of favoritism. All workers should have a perfect understanding of expectations. Both of their very own positions, and their behavior in the working place. The management should set consistent performance standards which should employees fail to meet; corrective action is taken by agencys practices. The most dominant correlation in the workplace is the member of staff and his/her supervisor. Managers can profit from on this facilitating open communication within employees themselves to bridge the gap between different generations that exist in the workplace. While several managers have acknowledged the fact that there is a shifting demographic in todays labor force, it is vital that the administration capitalizes on the variation by applying approaches to address the different prerequisites of the different generations.
