Java Installation - Hello World!

-


So you want to start programming? Everyone has to start somewhere, and the "Hello World!" is a great way to ensure that you have all of the requirements running on your computer to successfully start programming. Java will need to be installed on your computer before you can start coding. The links to Oracle's Java Development Kit downloads can be found here:

https://www.oracle.com/java/technologies/downloads/#jdk20-windows

Keep in mind to download the correct file for your Operating System. Download packets are available for Window, Mac, or Linux. Once the Java software kit is installed on your computer, picking an IDE or Integrated Development Environment is the next important step. NetBeans is a great IDE for Java development and is recommended on the Java tutorial pages. NetBeans can be downloaded at this link:

Java has a great step by step tutorial to complete the "Hello World!" project and verify that you system is good to go. The tutorial can be found at:

https://docs.oracle.com/javase/tutorial/getStarted/cupojava/netbeans.html

Follow the steps and complete your first program! The finished product should look something like:



You have officially begun the first steps to Object Oriented Languages. An object is just that: an object. An object can be a car, a plane, a person, a plate, or anything else in the real world. In programming, an object refers to an instance of a class. The class is what you just created that runs the part of the program that tells the computer to display the entered output. The way the program runs combined with the data structure (ADT or Abstract Data Type) is what makes up the class.

Employee Management System - Simple Project

-

  The employee management system project is designed to take user input and store the information as variables for later use. As Miller, Vahid, and Lysecky point out, a variable “is used to remember a value for later use" (2015). Creating the variables of employeeName, employeeSSN, employeePhone, employeeEmail, and employeeSalary were to hold the information to display later in the program. Variable types were string with the exception of the salary input that was set as an integer.             Repetition was very useful in writing this code. Each line was the same just changing the variable name and type in the string. Employee salary was the only line that had an addition with the sep= function to remove the space after the $ sign in the code. This was used for appearance purposes. Setting the variables to strings allowed the user to enter dashes if needed and parenthesis if desired for the phone number. Setting the variabl...

Explicit and Implicit Variables

-
  What is a Variable? Using implicit or explicit variables is an important decision when choosing what language to use when writing a program or starting to code. In simplest terms, a variable is used to remember a value for later use. The way different programming languages use variables is important for programmers to keep in mind when choosing how to code variables. Implicit variables are when the compiler chooses the type of output and explicit variables are when the programmer pre-assigns variables to have a specific output. Examples of Variables Each can be useful depending on the program that is being written. Boudreau points out that implicit variables can often be easier to use in programming and that sometimes the results can be just fine. However, leaving the compiler making that decision making on an assumption can often lead to problems. Explicit assigning of variables gives a more specific output and result and can be much more reliable. Depending on the lan...

Creating Tables in MySQL

  Creating Tables in MySQL           Creating tables in MySQL is important so that a user can add information, delete information, and update an entry using SQL statements. Also, a final statement was created to join all three tables demonstrating the relationships between the three tables. The INSERT function was used to add rows to the first table named tbldvdtitles. The information was inserted and the code and the results are pictured below: MySQL instructions were used by Oracle to guide the use of MySQL. The next table was a table called tbldvdActors with the information inserted and results below: Updating and deleting rows were part of the requirements for the interactive assignment and the following code was used: A third table was created to describe the relationships between actor ID and the ASIN number for each movie and the results were as follows: Joining all three tables was the last step and the results were as follo...
