如何检查两个数组是否相等？

解决方法

下面的示例演示如何使用数组的equals()方法来检查两个数组相等与否。

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("Is array 1 equal to array 2?? "
      +Arrays.equals(ary, ary1));
      System.out.println("Is array 1 equal to array 3?? "
      +Arrays.equals(ary, ary2));
   }
}

结果

上面的代码示例将产生以下结果。

Is array 1 equal to array 2?? true
Is array 1 equal to array 3?? false
