How can I optimize the performance of lists in Java?

To optimize list performance in Java, consider using the right type of list for your use case, like ArrayList for fast access or LinkedList for frequent insertions.

What are the differences between ArrayList and LinkedList?

ArrayList is backed by a dynamic array, providing fast random access, while LinkedList is a doubly-linked list, which allows for efficient insertions and deletions.

Are there any specific methods I should avoid when using ArrayList?

Yes, avoid using methods that require resizing the array frequently, like adding elements beyond its current capacity, as this can lead to performance overhead.

What about using streams for list operations? Is it efficient?

Using streams can be efficient for certain operations, but be cautious of overhead in performance-critical sections. Always benchmark your specific use case.
