JAVA TUTORIAL HOW TO CREATE AND USE AN INTEGER IN JAVA ?

In this video I touch on how you go about using the special java datatype Integer. This datatype is used to store whole numbers.

I kick off the video by breaking down the concept by giving a visual explanation using a tool called Paint. I try to explain what is an Integer yet also draw a diagram to give the viewer a better understanding of of the topic.

After the breaking down the concept I then progress to demonstrate a live coding session on How TO CREATE AND USE A INTEGER IN JAVA. I also program some basic program that will do basic calculations upon two values. I also intentionally create some bugs/errors that one can make when working on a java program.

This video covers the following content :

What is a variable?
How to declare a Integer in java?
How to do a basic calculation on two Integer values in java?
How to fix bugs mistakes when working with Integers?
What value and Integer stores ?
