Guess the output?

public class Main {
    public static void solve() {
        int first = 10, second = 20;
        int third = first + second;
        {
            int third = second - first;
            System.out.printf("%d ", third);
        }
        System.out.printf("%d", third);
        throw new RuntimeException("Something went wrong!");
    }
    public static void main(String[] args) {
        try {
            solve();
        } catch (Exception e) {
            System.err.println("Exception occurred: " + e.getMessage());
        }
    }
}
