// Get String Length using Stream API (codePoints)
    import java.util.Scanner; // Included for consistent structure, though not strictly used here

    // Main class containing the entry point of the program
    public class Main {
        public static void main(String[] args) {
            // Step 1: Initialize a string
            String str = "Hello World";

            // Step 2: Get an IntStream of code points from the string and count them
            long length = str.codePoints().count(); // count() returns a long

            System.out.println("String: \"" + str + "\"");
            System.out.println("Length (using Stream API codePoints().count()): " + length);
        }
