What are some optimization techniques for Java collections?
There are several techniques to optimize Java collections, such as using the right collection type, minimizing resizing, and leveraging parallel streams.
Can you explain how choosing the right collection type can impact performance?
Choosing the right collection type is crucial; for example, using an ArrayList for random access is faster than a LinkedList.
What about minimizing resizing? How can I do that?
To minimize resizing, you can initialize your collections with an appropriate initial capacity based on expected size.
Are there any specific scenarios where I should use a HashMap over a TreeMap?
Yes, use HashMap for faster lookups and TreeMap when you need sorted order of keys.
