Example: CountEvenOddJavaStreams in Java

// CountEvenOddJavaStreams
import java.util.Arrays;
import java.util.Scanner;

// Main class containing the entry point of the program
public class Main {
    public static void main(String[] args) {
        // Step 1: Declare and initialize the array
        int[] numbers = {2, 5, 11, 14, 17, 20, 23};

        // Step 2: Use streams to count even numbers
        long evenCount = Arrays.stream(numbers)
                               .filter(n -> n % 2 == 0) // Filter for even numbers
                               .count();                 // Count the filtered elements

        // Step 3: Use streams to count odd numbers
        long oddCount = Arrays.stream(numbers)
                              .filter(n -> n % 2 != 0) // Filter for odd numbers
                              .count();                // Count the filtered elements

        // Step 4: Print the results
        System.out.println("Array elements: " + Arrays.toString(numbers));
        System.out.println("Number of Even Elements: " + evenCount);
        System.out.println("Number of Odd Elements: " + oddCount);
    }
