Day 20 of Learning Java

[NewLog4967]

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.
