Hey john,so while playing around in a constructor, i noticed that either super, or this keyword needs to be the first statement in the constructor, could you please look into that and let me know why java has such a type of constraint?
I watched your video and I fell like I love Java

Hey what about the super keyword used in the parameter types of generic classes, like for eg, , what does this mean ??🤔
you're awesome man
loved it
Superb.
Thank You
super explanation.
Super video!
A Question:
Say, for example you had a condition that said, cat's name can't be longer than 5 characters. How can you validate that variable before passing it to the super() constructor?
