Java按顺序迭代和打印多个数组

import java.util.ArrayList;

public class Main {
    public static void main(String[] args) {
        ArrayList<int[]> arrays = new ArrayList<>();
        arrays.add(new int[]{1, 2, 3});
        arrays.add(new int[]{4, 5, 6});
        arrays.add(new int[]{7, 8, 9});

        for (int[] array : arrays) {
            for (int element : array) {
                System.out.print(element + " ");
            }
            System.out.println();
        }
    }
}

1 2 3 
4 5 6 
7 8 9
