How do I choose the right map in Java?

What factors should I consider when choosing a map in Java?

You should consider factors like performance, memory usage, and the specific operations you need, such as searching or sorting.

Can you explain the differences between HashMap, TreeMap, and LinkedHashMap?

Sure! HashMap is fast and allows null values, TreeMap is sorted and uses a red-black tree, while LinkedHashMap maintains insertion order.

When should I use a TreeMap over a HashMap?

Use TreeMap when you need sorted order or range queries. HashMap is better for faster access without ordering.

Are there any performance trade-offs I should be aware of?

Yes, HashMap has O(1) average time complexity for get/put, while TreeMap has O(log n) due to its tree structure.
