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

Class.getClassLoader介绍

[英]Returns the class loader which was used to load the class represented by this Class. Implementations are free to return null for classes that were loaded by the bootstrap class loader. The Android reference implementation, though, always returns a reference to an actual class loader.
[中]返回用于加载此类表示的类的类加载器。对于引导类加载器加载的类，实现可以自由返回null。不过，Android引用实现总是返回对实际类加载器的引用。
