How to Install Java and Object-Oriented Design Principles

Greeting fellow coders.  Today we will be starting to learn Java by first installing Eclipse and then the required JDK (Java Development Kit) in order for you to start coding.  Below you will find a list of both links and helpful video tutorials that will get you started with learning to code in Java.  I will try to include tutorials in both Windows and Mac just in case.  Have fun and if there are other links or videos that I missed feel free to mention that in the comments.  Good luck.

Some of the features of the object-oriented design principles can be found at: https://www.javaguides.net/2018/08/object-oriented-design-principles-in-java.html
