Serial and parallel stream in java

Question

Accepted Answer

Serial and parallel streams in Java are used for processing collections of data in a sequential or parallel manner.

Serial streams process elements in a single thread, while parallel streams use multiple threads for faster processing.
Parallel streams can improve performance for large datasets by utilizing multiple cores of the processor.
Serial streams are suitable for smaller datasets or when order of processing is important.
Use parallel streams with caution as they may introduce overhead and potential synchronization issues.
Example: List names = Arrays.asList("Alice", "Bob", "Charlie"); names.stream().forEach(System.out::println); names.parallelStream().forEach(System.out::println);
