If you are interested in using java tutorials to educate yourself from home, you are probably interested in learning how to tell the difference between valuable resource materials, and those which are outdated or incorrect. Learning to evaluate the quality of available tutorials is both an art and a science, and is best accomplished by paying attention to some of the individual components which make up a quality tutorial. We will take a look at four of the most important:
· Good organization – The tutorial needs to have a well-developed structure, which comprehensively details the content it will deliver, and is very easy for users to navigate. A good organizational structure is indicative of a polished educational thought process, and is more important than you may think in the development of a good tutorial.
· Valuable content – For good java tutorials, the content should be structured around accomplishing individual tasks. It should do so by providing clear instruction to the reader, and be concise and to the point as well. The delivery of quality content is the primary purpose of any tutorial.
· Attractive appearance – Attention needs to be paid to the manner in which the tutorial is presented. They should always strive to be visually appealing and not overly busy, so as to distract from communicating the message. A clean and simple presentation also helps to emphasize the content.
We are not all equally motivated. Some people have more self-drive than other people. This is why we find that some people always end up at the top even when the odds are against them. An employee, with this realization, through the Human Resource department, should be able to design efficient career development systems. For this system to work, the employer must understand the nature of the business environment in which they are operating.
Why Train Employees?
	The purpose of training employees is to enable them to grow with time and increase their efficiency. The business world is quite dynamic, nothing stays the same for long. Training one’s employees allows them to keep abreast with the ever changing technological advancements and many other factors that are relevant to his/her line of work. Employees cannot be expected to solve all their employer’s expectations with static skills and techniques. Even the most updated technology becomes obsolete at some point.
	People are the biggest assets in organizations. For an establishment to flourish, it is important that the employer understands certain key things that help spur their development.
In a report from the Harvard Business Review, “The Impact of Employee Engagement of Performance,” the most impactful employee drivers are:
This section of our beginning python training class always stumps students. Firstly, because they need to know the difference between a function and a method. Secondly, they need to understand object oriented programming concepts. Thirdly, they need to realize that python has three types of methods. Then they need to know how to use each method, which means they need to know the purpose of each method type. Then they have to understand mutable versus non-mutable types. The list goes on. As part of our python tutorial, I hope to shed some light on this confusing topic.
To begin, the difference between a function and a method in python is that a method is defined within a class. Here is an illustration:
#function def greeting(): print "Hello, I hope you're having a great day!" class HSGPrinter(object): #method def greeting(self): print "Hello, I hope you're having a great day!"
As should be obvious, the second definition of greeting is encapsulated within the HSGPrinter class and is , therefore, refered to as a method.
The astute reader will notice that the greeting method contains one parameter named self. For those who know C++ , Java or C#, self is equivalent to this i.e. it is a reference to the invoking object:
The importance of variables in any programming language can’t be emphasised enough. Even if you are a novice, the chances are good that you will have been using variables for quite a while now.
They are the cornerstone of any language and without them we would not be able to accomplish much of anything. However, most of you up until this point have probably only been working with standard variables, variables which can hold single values such as an integer, a single character, or a string of text.
In this tutorial we are going to take a look at a more special type of variable called an array. Arrays can seem quite daunting at first glance but once you get used to working with them you will wonder how you ever managed to program without them.
The reason arrays are special is because they can hold more than one value. Think about this: say you create a variable which contains a line of text like the code below:
