I'm trying to get a resource (image.png, in the same package as this code) from a static method using this code:
import java.net.*;
public class StaticResource {
public static void main(String[] args) {
URL u = StaticResource.class.getClass().getResource("image.png");
System.out.println(u);
}
}
The output is just 'null'
I've also tried StaticResource.class.getClass().getClassLoader().getResource("image.png");
, it throws a NullPointerException
I've seen other solutions where this works, what am I doing wrong?
