1. How does a HashMap handle collisions internally, and what changed in Java 8+?
Model Answer: HashMaps use separate chaining with linked lists at each bucket index. When a bucket exceeds the treeify threshold (8 nodes) and total capacity is at least 64, the linked list converts into a balanced Red-Black Tree, improving worst-case lookup from O(n) to O(log n).
