我需要帮助来显示所有偶数从输入集中的20个整数在java 13

import java.util.ArrayList;
import java.util.List;
import java.util.Scanner;

public class EvenNumbers {

    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);

        List<Integer> numbers = new ArrayList<>();
        System.out.println("请输入20个整数：");
        for (int i = 0; i < 20; i++) {
            int num = scanner.nextInt();
            numbers.add(num);
        }

        System.out.println("输入集中的所有偶数为：");
        for (int num : numbers) {
            if (num % 2 == 0) {
                System.out.print(num + " ");
            }
        }
    }
}
