我有一个arrayList，其中每个元素都是一个长度为整数的数组。如何在这里使用.contains方法？

import java.util.ArrayList;

public class Main {
    public static void main(String[] args) {
        ArrayList<int[]> arrayList = new ArrayList<>();

        int[] array1 = {1, 2, 3};
        int[] array2 = {4, 5, 6};
        int[] array3 = {7, 8, 9};

        arrayList.add(array1);
        arrayList.add(array2);
        arrayList.add(array3);

        int[] targetArray = {4, 5, 6};

        boolean containsTarget = false;
        for (int[] array : arrayList) {
            if (array.length == targetArray.length) {
                boolean isEqual = true;
                for (int i = 0; i < array.length; i++) {
                    if (array[i] != targetArray[i]) {
                        isEqual = false;
                        break;
                    }
                }
                if (isEqual) {
                    containsTarget = true;
                    break;
                }
            }
        }

        System.out.println("ArrayList contains target array: " + containsTarget);
    }
}
