October 10, 2024Rant: Java 8 streams are too little too late
Meh. Coming back to python after a few months with java and kotlin, I have to say brevity is a code virtue I don't value too highly, if at all. I find myself looking at function signatures mostly these days and not bother reading the implementation. I just trust that the code does what the interface says. If I'm the one writing the implementation, I don't care how much ceremony I have to do (as long as it's reasonable). I only have to write it once. It's a problem of course if the language has no types. That's why I like kotlin: required types at the top level with little ceremony in the API.

June 20, 2024 - Pipelining: Operations are combined into a pipeline to optimize processing. Internal iteration: Streams manage iteration over data sources internally. Streams can be created from various data sources, including collections, arrays, and more. An empty stream contains no elements. It’s useful as a neutral value in stream-based code. ... import java.util.stream.Stream; public class StreamExample { public static void main(String[] args) { Stream<String> emptyStream = Stream.empty(); System.out.println("Number of elements in the stream: " + emptyStream.count()); } }

java.util.stream (Java Platform SE 8 )
3 weeks ago - This code unnecessarily uses side-effects. If executed in parallel, the non-thread-safety of ArrayList would cause incorrect results, and adding needed synchronization would cause contention, undermining the benefit of parallelism. Furthermore, using side-effects here is completely unnecessary; the forEach() can simply be replaced with a reduction operation that is safer, more efficient, and more amenable to parallelization: List<String>results = stream.filter(s -> pattern.matcher(s).matches()) .collect(Collectors.toList()); // No side-effects!
