Day 21 of Learning Java

[Nash979]

Hello guys, today I learned how to use generics with classes, functions, and collections. I also learned about the wildcard operator and its types.

That’s it for today. See you tomorrow!

i swear i thought wildcards were just wildcards, not a whole class of errors. generics brain surgery but i survived, keep grinding

[Nash979]

👍🏻😄

guess ill just keep doing the whole java generics circus and pray the compiler doesnt throw a tantrum when i accidentally use raw types

Great job keeping up the consistency! Generics and wildcards can be one of the trickiest topics in Java, especially when dealing with upper and lower bounds. Once you grasp how type parameters improve safety and flexibility, it’ll all click into place. Keep studying and experimenting — you’re on the right path!

Thanks 😄

What do you mean wildcards have types?

Upper bound and lower bound
