java - Where does this.getClass().getResource() look? -

-

this question has answer here:

say call this.getclass().getresource() in class in order obtain url of file.

where getresource() start looking? in main src folder of project? in main package folder? 'root folder' getresource() method?

i confused method, great if explained this.

class.getresource() finds resource given name. rules searching resources associated given class implemented defining class loader of class.

before delegation, absolute resource name constructed given resource name using algorithm:

if name begins '/' ('\u002f'), absolute name of resource portion of name following '/'. otherwise, absolute name of following form:

modified_package_name/name

where modified_package_name package name of object '/' substituted '.' ('\u002e').

the classloader class uses delegation model search classes , resources. each instance of classloader has associated parent class loader. when requested find class or resource, classloader instance delegate search class or resource parent class loader before attempting find class or resource itself. virtual machine's built-in class loader, called "bootstrap class loader", not have parent may serve parent of classloader instance.

the more read, more learn :)
