An example of this is the customer object, which has a property value such as name, which needs to be returned after assigning a value to each property in the C program.Jniexport Jobject Jnicall Java_com_or

caches some classes, which improves the execution efficiency of the loadClass method. The other is packagesMap: this map maintains the package name of the class and the mapping relationship of UCL. For details about the logic of UCL to load class, see the following activity diagram:Shows the inheritance structure of UnifiedClassLoader3. The RepositoryClassLoader parent class of UnifiedClassLoader3 overrides the loadClass method of URLClassLoader and implements the logic.See the following code:R
