Relative Path Problem (getClass().getResource())

[desturrr]

I am having diffuculties while trying to make the path of my files relative.
I am using an interface to hold my static variables in order not to mix them with my other codes , just implementing the interface is sufficient to use the variables.

I need to give the address of my file as a parameter, and i am making it by using absolute path of file just like below .
>>static JLayerPlayer xLayer=new JLayerPlayer("C:/Java_Projects/Ney1/src/Sounds/plainSounds/xFile.mp3");

But i need to make them relative paths. When i try the code below.
>>static JLayerPlayer xLayer =new JLayerPlayer(getClass().getResource("/Sounds/plainSounds/xFile.mp3"));

I am getting an error says you can not use non-static getClass() method inside a static class or in interfaces, is there any other way to accomplish relative path inside interfaces.

Thanks in advance.

You can use class literal notation rather than getClass().

package my.pack;
 
import java.net.URL;
 
public interface Foo {
    static URL url = Foo.class.getResource("data.txt");
}
