关于java.class.Class的getResouce()方法分析

宝贝

Here in Sun's API
getResource
public URL getResource(String name)
Finds a resource with a given name. This method returns null if no resource with this name is found. The rules for searching resources associated with a given class are implemented by the * defining class loader of the class.
This method delegates the call to its class loader, after making these changes to the resource name: if the resource name starts with "/", it is unchanged; otherwise, the package name is prepended to the resource name after converting "." to "/". If this object was loaded by the bootstrap loader, the call is delegated to ClassLoader.getSystemResource.
Parameters:
name - name of the desired resource
Returns:
a java.net.URL object.
Since:
JDK1.1
