So You Want to Be an App Developer? Here's How [INFOGRAPHIC] Apps are in. There's no denying it. Seems everyone these days has a great idea for a mobile app: apps to find food, apps to find rides, apps to find more apps. But just how do you become an app developer anyway? A degree in computer science or software engineering is a very strong foundation. To do that, you'll need a well-rounded skillset, including UI design, familiarity with a range of programming languages, backend computing knowledge and — this one's very important — some savvy business knowledge. The online education portal Schools.com recently surveyed the app landscape, and pulled information from a variety of sources around the web to put together the infographic below, which serves as a primer for aspiring developers.

How to Swap Two Numbers without Temp or Third variable in Java - Interview Question How to swap two numbers without using temp or third variable is common interview question not just on Java interviews but also on C and C++ interviews. It is also a good programming questions for freshers. This question was asked to me long back and didn't had any idea about how to approach this question without using temp or third variable, may be lack of knowledge on bitwise operators in Java or may be it didn't click at that time. Given some time and trial error, I eventually come out with a solution with just arithmetic operator but interviewer was keep asking about other approaches of swapping two variables without using temp or third variable. Swapping two numbers without using temp variable in Java If you have ever heard this question, then you must be familiar with this approach of swapping numbers without using temp variable. int a = 10; int b = 20; System.out.println("value of a and b before swapping, a: " + a +" b: " + b); a = a+ b; //now a is 30 and b is 20 Output: int a = 6;
Why Hackers Are So Much Funnier Than You Are | Wired Enterprise Bob Nystrom, the brain behind a new programming language known as Vigil. Photo: Bob Nystrom Bob Nystrom is the author of the first programming language that automatically deletes your code if it doesn’t behave the way it’s supposed to. He calls his creation Vigil because it exhibits “supreme moral vigilance.” “When a Vigil program is executed, Vigil itself will monitor all oaths,” Nystrom writes in his description of the new language. “If an oath is broken, the offending function…will be duly punished. Many computer programming languages strive for safety, barring programmers from introducing common coding errors, bugs, and security holes. One coder thought Nystrom should take the idea even further. Vigil is nothing less than a work of programming genius. “Isn’t a language that deletes code crazy?” The popular stereotype is that hardcore techies are, well, humor-challenged. ‘Hacking is a rearrangement of form — and that’s what humor is. — Gabriella Coleman You don’t think Vigil is funny?
Java Школа Почему мы берем на работу и обучаем Java-специалистов, даже если они еще не имеют опыта работы на Java? Java — один из самых перспективных и функциональных языков программирования. Однако в этой сфере наблюдается определенный недостаток опытных кадров, из-за чего заработная плата Java-специалистов на 30–40 % выше, чем в среднем по рынку. В то же время 92 % работодателей не готовы вкладываться в обучение и развитие новых сотрудников, предпочитая искать специалистов с опытом работы. В Технологическом Центре Дойче Банка мыслят иначе: здесь хорошо понимают, что Ваши знания о любом объектно-ориентированном языке программирования позволят быстро освоить специфику разработки банковских продуктов на Java. Именно поэтому вы сразу станете полноценным сотрудником нашей команды профессионалов. Условия программы Как попасть в Java-школу? Для того чтобы присоединиться к команде Технологического Центра Дойче Банка в Москве или Санкт-Петербурге, нужно пройти через несколько этапов: 1. 3. 4. 5.
Scanner (Java Platform SE 7 ) A simple text scanner which can parse primitive types and strings using regular expressions. A Scanner breaks its input into tokens using a delimiter pattern, which by default matches whitespace. The resulting tokens may then be converted into values of different types using the various next methods. For example, this code allows a user to read a number from System.in: Scanner sc = new Scanner(System.in); int i = sc.nextInt(); As another example, this code allows long types to be assigned from entries in a file myNumbers: Scanner sc = new Scanner(new File("myNumbers")); while (sc.hasNextLong()) { long aLong = sc.nextLong(); } The scanner can also use delimiters other than whitespace. String input = "1 fish 2 fish red fish blue fish"; Scanner s = new Scanner(input).useDelimiter("\\s*fish\\s*"); System.out.println(s.nextInt()); System.out.println(s.nextInt()); System.out.println(s.next()); System.out.println(s.next()); s.close(); prints the following output: 1 2 red blue Localized numbers
File (Java Platform SE 7 ) An abstract representation of file and directory pathnames. User interfaces and operating systems use system-dependent pathname strings to name files and directories. This class presents an abstract, system-independent view of hierarchical pathnames. An abstract pathname has two components: An optional system-dependent prefix string, such as a disk-drive specifier, "/" for the UNIX root directory, or "\\\\" for a Microsoft Windows UNC pathname, and A sequence of zero or more string names. The first name in an abstract pathname may be a directory name or, in the case of Microsoft Windows UNC pathnames, a hostname. The conversion of a pathname string to or from an abstract pathname is inherently system-dependent. A pathname, whether abstract or in string form, may be either absolute or relative. The prefix concept is used to handle root directories on UNIX platforms, and drive specifiers, root directories and UNC pathnames on Microsoft Windows platforms, as follows:
