本文整理了Java中java.util.Objects.deepEquals()方法的一些代码示例，展示了Objects.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。Objects.deepEquals()方法的具体详情如下：
包路径：java.util.Objects
类名称：Objects
方法名：deepEquals

Objects.deepEquals介绍

[英]Returns true if both arguments are null, the result of Arrays#equals if both arguments are primitive arrays, the result of Arrays#deepEquals if both arguments are arrays of reference types, and the result of #equals otherwise.
[中]如果两个参数都为null，则返回true；如果两个参数都是基元数组，则返回数组的结果#等于；如果两个参数都是引用类型的数组，则返回数组的结果#deepEquals；否则返回#等于。

 * @param one One instance
 * @param another The other instance
 *
 * @return True if the two are considered equal; false otherwise.
 */
