Java Enums Explained in 6 Minutes

All about Enums in Java - Full tutorial with concrete examples.

Enums (short for Enumerations) are used in Java to hold types that have a certain finite set of values. But if you're new to enums, they can be a little confusing. In this Java beginners' tutorial video, we'll talk all about enums - how you can create your own enums, how to use them, and in what situation using an enum makes sense in your code. All in less than 6 minutes!

How does this man manage to break down these concepts so effectively, especially at such a quick pace?! These videos are a godsend. The way you add a small piece of code then fully explain why you added it and what it does makes the code extremely easy to understand. The humour along with the simple but creative programs is also a huge plus, very engaging. Thank you!!

Can you make a long tutorial about what a junior Java developer should know 100% to pass an interview or cover some core topics about it or a playlist of videos? Your videos are pretty understandable and informative, thank you.

[AhmedMusrin]

We had to implement the 2nd part of your video(with grades instead of cereal) as part of my exam(on paper). Without you, I would not have gotten it correct. Thank you!!!

I was trying to understand Enums in practice to implement in my C# code, but a Java video nailed it for me. Now I understand when my teachers said "learn the idea, not the syntax".

[valoriebroderick]

These tutorials are amazingly clear and understandable. I'm so grateful because that's not always the case with coding tutorials.

[DaBestOhYeah]

I am so glad that whenever I don't understand something in java, your videos are top on the list!!

The mutability of Enum fields is a nugget of wisdom, which i didn't anticipated. Thanks!

[hangyeollee-creuset]

Love your videos. John.
Thank you so much for making the videos.
It is pleasure to see you having fun in Java.

Bless you and your video(s). I started studying for the OCA and your videos are a big help in understanding the dry text from the book in minutes (literally), haha.

[faroukmatamir]

Thank you John, please keep going with new videos and don't stop, I am learning a lot from you....

sir
thanks so much
I really appreciate
I taught myself frontend development two years ago and I got hired recently as backend engineer.
since I recently started learning java, I was struggling on something on my assignment and this video basically explain everything.
your example is similar to the problem I have .
I right away subscribe and will recommend this channel to my friend
I want to say thank again

Hi John, another nice thing about enums is that you can use abstract methods to customize the constants :)

[isaacweber]

Much gooood John. God Bless you! Keep doing that. It's helping me a lot.
