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

System.load介绍

[英]Loads and links the dynamic library that is identified through the specified path. This method is similar to #loadLibrary(String), but it accepts a full path specification whereas loadLibrary just accepts the name of the library to load.
[中]加载并链接通过指定路径标识的动态库。此方法类似于#loadLibrary（String），但它接受完整路径规范，而loadLibrary只接受要加载的库的名称。
