In our previous example, we had a class with a default constructor where we passed no arguments into the class. That is great, unless you want to set one or more class variables with data at run time. So lets look at overloading the class constructor. In this example, we keep our default constructor, but…
This introduction/refresher to Java Classes is assuming that you’ve worked with some Object Oriented language before, like C++, or maybe even Java and you just need a quick refresher. In Java, everything you build will be a class, with very few exceptions. to define a class, you will need a file name, with the same…
Flowcharts and Pseudo-code work really well in certain situations, like when you have a defined task that needs to be completed, and/or your program follows a simple logical flow. However, in today’s modern computer application, users will perform things out of order because they can with a modern graphical user interface (GUI). As a developer,…
Pseudo-code, is essentially “fake code”. Well if it’s fake, why should we use it? That is a good question, so let’s look at what it is used for, and isn’t. Flowcharts are often used to help define the flow of an algorithm. However, they often get long, and hard to manage, especially with larger and…
If you need to see how to install Visual Studio Community Edition, please follow the video below. This video goes over installing all of the components one would reasonably need if they were working on their Comp. Sci. degree with me at Tusculum University, or another university, as it shows how to install for C++,…
Python is a high-level, general-purpose programming language. You can find it used in many different types of problems. It is probably most popular in science, math, and system scripts – often replacing other scripting languages and tools. This is in part because Python is very flexible and extensible. Meaning it can be added on to…

Let’s look at some other examples we might have with Java in this quick refresher. When using a local variable (i.e. one inside of a function, you don’t need to give an access modifier (private, protected, package, or public). However, you do need to provide it with a name (sometimes called an identifier) and a…
