Different programming languages gain popularity for different features. Java tutorials have proven particular popular over a long period of time, thanks to a diverse group of strengths inherent to the language itself. Let’s examine some of the basic elements of Java, and find out what it is both powerful and popular:
· WORA – Write Once Run Anywhere is a programming ideal that has never been effectively achieved. The goal is to be able to write code a single time, and have it deploy in the same way across multiple platforms. Although it is still an ideal, proper Java tutorials exist that demonstrate how we are moving closer to success.
· Object-Oriented – This programming philosophy designates that there is no coding that takes place outside established class definitions. A large class library is also available right within the core language pack.
· Compiler plus Interpreter – Once you have written your code, you can compile it into bytecodes which are then fed into a JVM, or Java virtual machine. You can then follow popular Java tutorials to see how you can extensively debug your code using this functionality.
Sage wisdom states that there are two sides to every coin. This timeless wisdom will be borne out in spades with Windows 8/RT. Let's get into the dark side first.
If your users are veterans of Windows it is safe bet they are going to take one look at Windows 8 and scream blasphemy. Users whose brains are geared towards visual learning will undoubtedly yell the loudest and longest.
There's a good reason for this. Mick Jagger brought his band to the Redmond campus, performing live "Start Me Up" in the summer of 1995 (it was a great show). This heralded in the abandonment of program icons sitting on the desktop and introduced the now legacy Start button.
Ending the life of the 17-year-old start button is not going to go well with some users.
How Can Managers Work More Efficiently with IT?
Would you rather work under someone who is an excellent developer but lacks people skills or leadership capabilities - or for someone that has excellent people skills, communicates well, and is a great leader but has limited understanding of productive coding practices? That’s not to say that the choice is one or the other but in many professional situations it does.
Managing an IT staff comes with numerous challenges, especially if the manager has no previous experience with the coding necessary for completing the project. Managing a business and IT's execution of tasks vary greatly in required skill sets, but it's important to find a cohesive and cooperative middle ground in order to see a project to its end. To fully grasp the intricacies of IT's involvement in the project at hand, managers can do the following to help further their efforts.
Get a basic understanding of coding and technical practices necessary for the project at hand by taking the time to research and practice enough to get a grip on the concept. This will allow managers insight on what their IT folks are really working on daily. Expertise in a programming language is not required, only an overview of the stuff that matters, i.e. understanding the concept of OOP (Object Oriented Programming.) Having this knowledge cannot be overlooked and will gain respect among multiple spectrums in the organization.
In Python, we can create three types of methods in a class: instance or regular method, classmethod and staticmethod. Instance methods are associated, as the name infers, with an instance or object of the class and take self as the first parameter. Classmethods take a reference to the class, cls, as the first parameter of the class. Staticmethods, for the most part, are convenience methods that could be declared as functions since they really do not have much to do with the class itself. They were probably added at some time after the advent of Python in order to make the language more object oriented i.e. minimize the number of free floating functions.
Refer the our article static, class and regular methods in Python for a detailed explanation on this subject.
