本文整理了Java中java.util.Arrays.deepEquals()方法的一些代码示例，展示了Arrays.deepEquals()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Arrays.deepEquals()方法的具体详情如下：
包路径：java.util.Arrays
类名称：Arrays
方法名：deepEquals

Arrays.deepEquals介绍

[英]Returns true if the two given arrays are deeply equal to one another. Unlike the method equals(Object[] array1, Object[] array2), this method is appropriate for use for nested arrays of arbitrary depth.

Two array references are considered deeply equal if they are both null, or if they refer to arrays that have the same length and the elements at each index in the two arrays are equal.

Two null elements element1 and element2 are possibly deeply equal if any of the following conditions satisfied:

element1 and element2 are both arrays of object reference types, and Arrays.deepEquals(element1, element2) would return true.

element1 and element2 are arrays of the same primitive type, and the appropriate overloading of Arrays.equals(element1, element2) would return true.

element1 == element2

element1.equals(element2) would return true.

Note that this definition permits null elements at any depth.

If either of the given arrays contain themselves as elements, the behavior of this method is uncertain.
[中]如果两个给定数组彼此非常相等，则返回true。与方法equals（Object[]array1，Object[]array2）不同，此方法适用于任意深度的嵌套数组。
如果两个数组引用都为null，或者它们引用的数组具有相同的长度，并且两个数组中每个索引处的元素相等，则认为这两个数组引用是完全相等的。
如果满足以下任一条件，则两个空元素element1和element2可能完全相等：
element1和element2都是对象引用类型的数组和数组。deepEquals（element1，element2）将返回true。
element1和element2是相同基元类型的数组，并且是数组的适当重载。equals（element1，element2）将返回true。
element1==element2
要素1。equals（element2）将返回true。
请注意，此定义允许任何深度的空元素。
如果任意一个给定的数组都包含自己作为元素，则此方法的行为是不确定的。
