哪些是 Java 的系统类? [英] Which are Java's system classes?

问题描述

在阅读一些关于断言的文档时，我发现:

java -ea -dsa

<块引用>

"一般情况下启用断言，但是禁用系统中的断言类."

哪些是系统类?

解决方案

根据断言文档，系统类是没有显式类加载器"的类，即由引导类加载器加载的类.AFAIK 表示 rt.jar 的内容，整个标准 API.

When reading some documentation about assertions, I found:

java -ea -dsa 

"Enables assertions in general, but disables assertions in system classes."

Which are the system classes?

解决方案

According to the assertions documentation, system classes are classes "which do not have an explicit class loader", i.e. the classes loaded by the bootstrap classloader. AFAIK that means the contents of rt.jar, the entire standard API.
