如何比较两个数组的元素？[复制]

问：

我正在尝试检查一个数字是否是回文，我把数字放在一个字符串中，然后把它们放入一个数字数组中，我能够将这个数字数组反转为一个新数组。现在我想检查一下.请注意，我在这里的相等意味着两个数组在相同的索引下获得相同的元素。numbersL[]==numbersLreversed[]

import java.util.*;

public class Array_and_its_reverse {

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

        String numberS = in.next();           //12121

        String numbersarrayed[] = numberS.split("");      // put numbers in a string array
        long numbersL[] = new long[numbersarrayed.length];   // original
        for (int i = 0; i < numbersarrayed.length; i++) {

            numbersL[i] = Long.parseLong(numbersarrayed[i]);
            System.out.println(numbersL[i]);
        }

        long numbersLreversed[] = new long[numbersarrayed.length];

        System.out.println("Array in reverse order: ");

        for (int i = numbersL.length - 1; i >= 0; i--) {

            numbersLreversed[i] = numbersL[i];
            System.out.println(numbersLreversed[i]);

        }
        if (numbersLreversed == numbersL) {
            System.out.println("right");
        } else {
            System.out.println("NO");
        }

    }

}
