Is it possible to check if two arrays are not equal
提问by nmu
I'm aware of the fact that I could just do a:
我知道我可以做一个：
while(Arrays.equals(array1, array2))
and then just write the code needed in the elsestatement.
然后只需编写else语句中所需的代码。
Is there any other way to check if they are not equal?
有没有其他方法可以检查它们是否不相等？

Whats wrong with
怎么了
if( !Arrays.equals(array1, array2) )
if( !Arrays.equals(array1, array2) )
array1.equals(array2)is the same as array1 == array2,
i.e. is it the same array. And it's not what most people expect.
array1.equals(array2)与 相同array1 == array2，即它是同一个数组。这不是大多数人所期望的。
Arrays.equals(array1, array2)compares the contents of the arrays.
Arrays.equals(array1, array2)比较数组的内容。

How about
怎么样
if (!Arrays.equals(array1, array2))
Or is that what you mean in your example?
或者这就是你在你的例子中的意思？

I don't think you want a while, but an if, since a whiledoesn't have an else-clause. You can use a negation operator (!) to check if the arrays are not equal like this:
我不认为你想要 a while，而是一个 if，因为 awhile没有 -else子句。您可以使用否定运算符 ( !) 来检查数组是否不相等，如下所示：
if(!Arrays.equals(array1, array2))

if ( !Arrays.equals(array1, array2) )
// their contents are not equal
