      • getResource

        public java.net.URL getResource​(java.lang.String name)
        If we want to load a resource and it is available in both the parent classloader and the child classloader, then the default behaviour is, first it will check in the parent classloader if it not found then it will check in the child classloader. So if we want to load the this type resource, we will always get the resource from the parent classloader, child's resource will never get loaded. To solve this first we are checking in the child classloader, if it is not found then checking in the parent classloader.
        Overrides:
        getResource in class java.lang.ClassLoader
        Parameters:
        name - The resource name
        Returns:
        A URL object for reading the resource, or null if the resource could not be found or the invoker doesn't have adequate privileges to get the resource.
