Java判断数组是否相等

import java.util.Arrays;

public class Main {
   public static void main(String[] args) throws Exception {
      int[] ary = {1,2,3,4,5,6};
      int[] ary1 = {1,2,3,4,5,6};
      int[] ary2 = {1,2,3,4};
      System.out.println("数组 ary 是否与数组 ary1相等? ："
      +Arrays.equals(ary, ary1));
      System.out.println("数组 ary 是否与数组 ary2相等? ："
      +Arrays.equals(ary, ary2));
   }
}

数组 ary 是否与数组 ary1相等? ：true
数组 ary 是否与数组 ary2相等? ：false
