Example: FindLargestAndSmallestUsingIteration in Java

// FindLargestAndSmallestUsingIteration
import java.util.Scanner;

// Main class containing the entry point of the program
public class Main {
    public static void main(String[] args) {
        int[] numbers = {12, 5, 8, 20, 3, 15}; // Example array

        // Step 1: Initialize max and min with extreme values
        // Integer.MIN_VALUE and Integer.MAX_VALUE are used
        // to ensure any array element will be correctly identified
        // as either larger than current max or smaller than current min.
        int max = Integer.MIN_VALUE;
        int min = Integer.MAX_VALUE;

        // Step 2: Iterate through the array
        for (int i = 0; i < numbers.length; i++) {
            // Step 3: Compare current element with max
            if (numbers[i] > max) {
                max = numbers[i]; // Update max if current element is larger
            }

            // Step 4: Compare current element with min
            if (numbers[i] < min) {
                min = numbers[i]; // Update min if current element is smaller
            }
        }

        // Step 5: Print the results
        System.out.println("Array elements: " + java.util.Arrays.toString(numbers));
        System.out.println("Largest element: " + max);
        System.out.println("Smallest element: " + min);
    }
