Thank you for your informative video for Spring JWT and Switch case. It would be better if you post JDK 17 others features too.

[jithinmv]

Please update us with all latest features of jdk 17 :)
Thank you for all these lectures

[anshupanda]

2:17 i think from jdk 7, we can use even String also. Pre jdk 7 only , integral type & enum we can .

[kapilausarmal]

Awesome...! Very Informative Video. Thanks for making this. There is any update in JDK 11 for Switch Expression?

[Srini]

Hi Basant please start videos on reactjs concepts and implementation and integration with spring boot

[vengateshm]

Kotlin has this kind of switch as when from its initial version itself.
Java is benchmarking good features from kotlin and introduced features like records, sealed classes etc., .

[sairammanchala]

Can u do a video about spring boot with login through google mail login and Facebook login and login through sso with different protocols like azure, okta etc..

[thiago]

It seems to me, a little bit poor style, create a switch with inner if, because you can create another switch with another if and so on. Let's use these feature in a wise way. It not that the feature is there we should use, in all cases, is good to know that exists.

[yacinedrissi]

Hi hello thank you for your effort, so how about k8s to deploy crud apps spring boot and database and angular thank you for advance

[amitddogras]
