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

System.identityHashCode介绍

[英]Returns an integer hash code for the parameter. The hash code returned is the same one that would be returned by the method java.lang.Object.hashCode(), whether or not the object's class has overridden hashCode(). The hash code for null is 0.
[中]返回参数的整数哈希代码。返回的哈希代码与java方法返回的哈希代码相同。lang.Object。hashCode（），无论对象的类是否已重写hashCode（）。null的哈希代码为0。
