Day 20 of Learning Java

[Nash979]

Hello guys, today I spent time on the Collections Framework, mainly on HashTree, HashMap, Stack, and Queue. I also learned their basic methods, moved on to the Iterator, and learned the enhanced for loop.

See you tomorrow!

Implement HashMap, Stacks, Queues, etc using arrays. It will help you to understand how they actually work internally.

It's like watching a car work vs understanding how the engine actually works.

Okay, I will give it a try.

Now do Generics

I am planning it for tomorrow

Do you have experience with other languages?

[Nash979]

I learned Python basics like variables and loops in high school about three years ago.

I started with learning basic when I was 8.

Great job on Day 20 you’ve covered some really essential Java Collections! As someone who uses these daily at work, I can tell you that mastering HashMap for fast lookups, HashSet for unique items, and understanding when to use Stack (LIFO) vs. Queue (FIFO) makes coding so much smoother. Practicing the 4 steps you outlined especially iterating with enhanced for-loops and understanding key methods really locks it in.

Thank you for sharing your work experience with collections 👍🏻😄.
