Java Tutorial for Beginners - 31 - Getters and Setters

In this tutorial we will discuss getters and setters and encapsulating your variables.

[jameswhyte]

You are truly the best I've seen on youtube at explanating Java concepts.

[thomaslinssen]

I allready knew and used getters and setters, but i never thought about protecting your code like that, with those if statements. Great explanation, thank you.

[ezinneosuagwu]

I have never really understood the use of getters and setters. I have battled with these concepts for a long time! You explained it so simply. Thank you so much! You are awesome!

[dapianna]

I'm currently taking APCS A and you're a godsend. I'm actually understanding things for the first time. Thank you!

[MrGamerAsian]

1 minute in and your video has already helped me immensely. Thank you so very much

[crazyxs]

so basically in summary:

imagine if we have hundreds of methods
and we need to change a value of a variable many months later
but we forget the rules or conditions of a certain variable
thats why we make variables private
so only through the public methods: through the setter we can change a value, with the condition,
and through the getter, we simply just return the value.

Thank you this makes it so much clearer :)

I really like how you go step by step on where the value goes. That was needed because it was getting hard for me to understand what was going on when I was studying in my uni. I needed some kind of visual mapping

[abdullahiahmed]

Absolutely simple, intuitive and lucid.

Larry, keep your Orcs at 9. Love it, lol

[owningyourfinances]

THANK YOU!!! You are DA MAN!!

So I'm in this online class to learn Java (scratches head), now I know that I can just get youtube/EJ Media and learn it better.

[h.cazador]

That was a beautiful example that i understood well! Thank you.

[anamikaahmed]

Short and simple..thank you for such a clear explanation :)

[qazzy]

Great tutorial and great example. Thanks man.

[arisamatore]

im just trying to understand the getters and setters and im looking at as many explanations for this and why its needed, and this example with orcs, and that they dont fit in to the cave thing made everything clear now.

[josephgagnon]

Great simple and clear explanation! :-)

[blakeharrison]

Thanks man, this tutorial is legendary

[anasslyan]

Great explanation, I just have a question, so if we are going to use setters to initialize the instances variable of the class, why do we need a user defined contractors with parameters that will have no control on the user input to initialize the instance variable?

[hamzahayd]

basically you made everything so easy.

[FL.S]

Great explanation, man. I had a hard time understanding this concept with how my professor teaches. You helped a lot, lol

[maksymkarunos]

Guys, I `ve got a problem, the programm does not allow me to to put key-work "static" to the main method since it does not go along with "setHeight'. Help please
