How does java.lang.Object class load native fucntions?

Question

When I create JNI code I must use System.load() or System.loadLibrary() method to load DLL created in C or C++ in order to use native functions.

But how do classes like java.lang.Object or java.lang.System load their own native functions like hashCode() or clone() or setOut0(PrintStream out) , and where does that library reside?

Answer 1

JVM通过JNI函数RegisterNatives()代表Object和其他一些类执行此操作。
