If you’re worried about the depth of recursion or prefer a more performance-optimized solution, consider using an iterative approach to calculate java gcd. This avoids any recursion limit issues:

public class GCDIterative {
    public static int gcd(int a, int b) {
        while (b != 0) {
            int temp = b;
            b = a % b;
            a = temp;
        }
        return a;
    }

    public static void main(String[] args) {
        System.out.println("GCD using iteration: " + gcd(36, 60));
    }
}

:white_check_mark: Why use this? This method is iterative, avoids deep recursion calls, and tends to perform faster, especially when dealing with larger inputs, ensuring reliable java gcd calculations for all use cases.
