oh my goodness gracious

SORT BY: "Most Verbose"

Actually it does return an int: https://docs.oracle.com/en/java/javase/17/docs/api/java.base/java/util/OptionalInt.html#getAsInt()

If it wasn't the code wouldn't even compile.

It isn't ideal because it return an OptionalInt and not an int

Like @goodman965 saying, i think all this codes with s.split(" ") are not working if there is double-spaces inside the given string, meanwhile if you use s.split("\s+") you are taking care of any number of spaces.

does not work with double space

Very impressive.

This one is not the fastest, cause it needs 2n reads, am i right?

Some people only use one line of code, maybe that's the difference.

Wow I don't even know how to read it. Nice job.

I don't see any iteration to put the elements into the stream. This solution seems fine to me.

Try this:

public static int findShort(String s) {
  String[] words = s.split(" ");
  Stream<String> stream = Arrays.stream(words);
  Arrays.fill(words, null);
  return stream.mapToInt(String::length)
               .min()
               .getAsInt();
}

You'll get a NullPointerException because no copy of the array is created.

lambdas interesting.....still trying to learn
