getSource in Java gets error

Question

My project JavaBasic gets NullPointerException at this line :

url = this.getClass().getClassLoader().getResource("/JavaBasic/res/sfx_wing.wav");

I think my getResource method get problems and it's relevant to Classpath, how can I set it ? Thanks!

Provide error logs and what you already tried to solve it – Brandon Zamudio May 10 '17 at 20:05 — Brandon Zamudio, May 10 '17 at 20:05

Put the file sfx_wing.wav at the at level of the package of class calling the url. This if the class calling the url is in the package stackoverflow, put the file at the same level as the stackoverflow.

my-java-project
  src
    stackoverflow
     ClassCallingUrl
    sfx_wing.wav

Then used this call.

url = this.getClass().getClassLoader().getResource("sfx_wing.wav");

OR

url =this.getClass().getResource("/sfx_wing.wav");

Much explanation can be found here.

I've just tried creating a package and move .wav file to it, then set path to start from the package's name the it works fine. – Thien Anhhhhh May 11 '17 at 12:49
