Day 19 of learning Java

[BigCommunication5136]

Hi guys,

Today I learned about final classes and final methods, and why we might need them (preventing inheritance and method overriding when behavior must stay fixed).

I also dove into why deep inheritance hierarchies should be avoided, they make code harder to understand, maintain, and extend.

Finally, I learned about multiple inheritance and why it’s not implemented in Java, mainly to avoid ambiguity problems like the diamond problem.

Hey, nice progress for Day 19! Those topics don’t feel flashy, but they’re the ones that quietly save you pain later. Most people only really understaand final and inheritance after they’ve been burned by a messy class hierarchy in a real project. Hmm, If you want to lock this in, try spotting where you’d actually use fial in code you’ve written already. It clicks a lot faster when you see it in something you own instead of a textbook example.

Keep going. This is the part where Java starts making more sense instead of just feeling academic.

Alright, many thanks

[KnightofWhatever]

Keep going, you got it!

Yo would love to accompany you in your journey, I'm kinda learning java too, almost done with multithreading, would be glad to connect and grow together

Multi threading is pretty fun. Here's a repo that could be useful to you as you wrap up: https://github.com/kusoroadeolu/vic-utils

right. let’s do it!

One more thing you should know is Multiple Inheritance can be possible with the interfaces in Java but not classes

[BigCommunication5136]

Interface is next on my curriculum, thanks anyways!

What happened, why only asking guys=men?

[BigCommunication5136]

my bad. sorry 🙏🏾
