What are some performance tips for using Java 8 Stream API?
To optimize performance with Java 8 Stream API, consider using parallel streams for large datasets, avoid unnecessary operations, and use primitive streams when possible.
Can you explain how parallel streams work?
Parallel streams utilize multiple threads to process data concurrently, which can significantly speed up operations on large collections.
What are the downsides of using parallel streams?
The downsides include potential overhead from thread management, increased complexity, and not all operations benefit from parallelization.
How can I measure the performance of my streams?
You can measure performance using the System.nanoTime() method before and after your stream operations to calculate the execution time.
