What is printed as a result of executing the following code segment?

public class ArrayAnalyzer {
    
    public static int findSecondLargest(int[] arr) {
        if (arr.length < 2) {
            return -1;
        }
        int largest = arr[0];
        int secondLargest = arr[0];
        
        for (int i = 1; i < arr.length; i++) {
            if (arr[i] > largest) {
                secondLargest = largest;
                largest = arr[i];
            } else if (arr[i] > secondLargest && arr[i] != largest) {
                secondLargest = arr[i];
            }
        }
        return secondLargest;
    }
    
    public static void main(String[] args) {
        int[] numbers = {3, 7, 2, 9, 5, 9, 1};
        int result = findSecondLargest(numbers);
        System.out.println(result);
    }
}```
