• Generic classes(Using type hierarchies, setting type upper bounds, null checking) / Handling exceptions with check function • Generic in/out, Covariance/Contravariance , reified, star projections, annotation • Googling time reading several articles (1) (2) (3) related with generics & inheritance (third was especially helpful..)
• Yesterday I just went through basics of generic in kotlin, so I never expected rest of this part will take so long. Generic in&out part took quite a lot of time to understand. 🤢 After some googling I was able to understand it roughly, but still didn’t understand the hood of it yet. • Somehow I feel I spent too much time and energy on this generic thing.. I got quite frustrated when I felt quite stuck, and was hard to proceed. However as I clicked the same lecture again at night(dawn?), it sounded easier. I should handle this balance of keeping pace while filling out the holes & vice versa.
• Finish functional manipulation (- Don't get stuck somewhere too long ! )
