What are some advanced techniques for using Java Streams?
Advanced techniques for Java Streams include parallel processing, custom collectors, and using Optional effectively.
Can you explain how to create a custom collector?
Sure! You can create a custom collector by implementing the Collector interface, defining how to accumulate elements.
What is the benefit of using parallel streams?
Parallel streams can improve performance by utilizing multiple cores for processing large datasets concurrently.
How do I handle exceptions in streams?
You can handle exceptions in streams by using try-catch blocks within the lambda expressions or by using custom wrappers.
Are there any performance considerations I should be aware of?
Yes, consider the overhead of parallelism and the size of the dataset; not all operations benefit from parallel streams.
