What are the differences between ArrayList and LinkedList in terms of performance?

ArrayList offers faster random access, while LinkedList provides better performance for insertions and deletions.

Are there any specific methods to improve the performance of HashMap?

Yes, you can optimize HashMap by choosing an appropriate initial capacity and load factor to minimize rehashing.

What about using Streams? Do they affect performance?

Streams can simplify code but may introduce overhead. Use parallel streams for large datasets to improve performance.
