Java Beginner Lesson 1

Welcome to Java Beginner Lessons Lesson 1.
 

First we will define what Java is.  JAVA is a programming language that you can write programs with to run on computers.

We begin learning how to write programs in Java by writing a program, like this one:
 

class JavaOne
{
}
 

This is a complete Java program because it does not create a compiler error.  What is a compiler error?  COMPILER ERROR is what happens when you try to compile your program and the compiler gives you back your errors.  Why do you have to compile your program?  Compiling your program is the first step to turning your program into a code that can be read by the computer.  The computer has its own language and it does not understand English or any spoken language.  Therefore, you need a compiler to translate your program into a code executable by a computer.

 

Let us look now in detail into the workings of our first program, word for word, and symbol by symbol.

class is a Java keyword.  JAVA KEYWORDS are the words that Java understands.  For example, if someone says "person", you immediately refer that word to a human being.  The same translation of a keyword happens in Java, except to Java, "person" is not a keyword.

JavaOne is a word that a person who wrote the program just made up.

{ and } are OPEN BRACE and CLOSED BRACE and both symbols are JAVA SYMBOLS OR WORDS that Java understands.

PRELUDE TO POWERPOINT

Selling can be easy or it can be hard.  Sometimes having someone or something to facilitate your selling performance will make selling easy for you, and might also give you some easy sales.  And there's nothing wrong with easy sales.

Microsoft PowerPoint presentation software might be able to facilitate your selling performance.  It has many functionalities that your clients might like to see in your presentation.  Here is an overview of the basic elements of this presentation software.

• SLIDE FUNCTIONALITY just like the old slide projector when photographs were produced in slides.
• GRAPHICS in the slides that come in the form of a digital camera picture or clipart images.
• PIE CHARTS AND BAR GRAPHS come in handy for visual effects.
• PREDESIGNED TEMPLATES ready-made so one just needs to enter texts and graphics into the slides.

POWERPOINT ===> TEXTS == GRAPHICS == IMAGES == CHARTS == PICTURES.

PowerPoint may indeed help out in adding dimension to your sales.  However, businesses should determine for themselves if a product is going to help them, or if it will just end up sitting in the computer memory hardware unused.

PROJECT MANAGEMENT

Starting a business or being in business for less than a year can be a challenge.  There are some things to consider before or during your first year in business.  Moreover, there are some things that you may not remember to address.

Thinking of your business as a project that you need to complete and succeed upon might help you decide on starting a business or succeed in business.  The following are the nine (9) areas of knowledge of Project Management used by many project managers employed by businesses and government agencies.

PROJECT INTEGRATION MANAGEMENT is the integration of all your knowledge, e.g., technical, clerical, into your business.

PROJECT SCOPE MANAGEMENT is how far your business will go in order to provide the services or product of your business.

PROJECT TIME MANAGEMENT can be the time you will devote to the business until you feel the business is not worthy of your time.

PROJECT COST MANAGEMENT is how much you have in your budget for your business.

PROJECT QUALITY MANAGEMENT can be the quality of service or product you will provide to your clients.

PROJECT HUMAN RESOURCE MANAGEMENT deals with the people you will employ to help you conduct your business.

PROJECT COMMUNICATIONS MANAGEMENT is all about the technologies and techniques you will employ to communicate with your employees, clients, and vendors.

PROJECT RISK MANAGEMENT is about limiting yourself from business transactions that you cannot assumed.

PROJECT PROCUREMENT MANAGEMENT is about getting the resources that you need to provide the service or the product of your business.

OPEN TO PROGRAMMING

Investment Department is invested in the continuing existence and possible progress of the business.  Therefore, it is only proper that the business uses technology that it will not outlast when the business grows.

One of the investment the business could make is in the existing technology available for accounting and database recording.  Available software for these two (2) areas of business application, however, are not that many.  The reason for this is that the greatest consumer of business software, i.e., the large companies, do not use them.  Instead, large companies and organizations, like the U.S. government, hire programmers to make programs for accounting and database recording that are usable only inside the company or organization.

Let's take a brief look at these available accounting and database recording software.

QuickBooks is limited to 14,500 individual records in totality of all different records.  This limit is not viable to a large company's ever-growing list of customers, employees, and vendors.

Microsoft Excel 2013 is a spreadsheet software limited to 2 GB file using a 32-bit microprocessor.  Using a 64-bit microprocessor, this file size is limited only by the PC system RAM size.  Excel, however, is not a database software.

Microsoft Access is limited to a database file of 2 Gigabyte and a limit to each individual record of 2,000 characters.  These restrictions will certainly make large companies to consider other alternatives.

Fortunately, there are existing programming languages that can offer a large company or a large organization, like the U.S. government, a viable solution to their current and future needs.  Among the most popular programming languages in use today are the following:  Java, C, C++, Visual Basic, and the old standards, COBOL and Fortran.

HIGH COST OF SMOKING

The Health Department is concerned about the health of all the employees of the business.  And some businesses has made it a policy of not hiring people who are smokers of cigarette or tobacco.  And the reason for this is usually twofold.

 

First, people who smoke have a higher chance of developing illness while at work or as they mature in their lifetime.  This will lead to sick days being used by an employee who smoke.

 

In the long and short terms, employees who smoke will lead to the business costing more insurance premium money insuring these employees.  Insurance companies recognize the ill effects of smoking for an insured member, therefore, they charged more insurance premium for these members to cover their possible costs.

 

In the future terms, insurance companies recognize that an insured member who smoke will cost them more money as the insured member reaches old age and starts to feel the real effects of his longtime smoking habit.

 

NONSMOKERS == LOW COST INSURANCE

SMOKERS ====== HIGH COST INSURANCE

The second reason of the twofold reason why a business will not hire people who smoke are the effects of second hand smoke on the workforce.  Second hand smoke comes from a person who smokes.  Not only is there second hand smoke while the smoker is smoking, but there is also second hand smoke even many hours after the smoker has smoked.  Usually second hand smoke stays in the smoker for as long as he lived, or until he stops his smoking habit.

COMPUTER TECHNOLOGY 101

Computer Technology 101

The five (5) major components of a Personal Computer (PC) system are the following, in the order of their importance:
1.  Central Processing Unit (CPU) is the component that does all the computations and control of the PC system.
2.  Main/Internal/Primary Memory component is where all the raw data and the computed data is stored.
3.  Input Device components are the device that a user will use to communicate with the CPU.
4.  Output Device components is how the PC system will be able to communicate to the user.
5. Secondary/Drive Storage Device components are where the user must save his data and his programs if he wants to use them again after turning off the PC system.

                                        (Pentium, Core)
INPUT DEVICES =====> CPU <=====> INTERNAL MAIN MEMORY
(keyboard, mouse)             |                   (RAM, ROM)
                                          |========> SECONDARY STORAGE DEVICE
                                          |                    (hard drive, floppy drive)
                                          |========> OUTPUT DEVICES
                                                               (console, printer)

Happy computing!
