Error in sound player

I tried to test sound file but there is no respond. Can some one tell me the reason. The music.play become yellow and the following error is on consol: NullPointerException

Here is the code:

import processing.sound.*;
SoundFile music;

void setup() {
size(400, 400);
music = new SoundFile(this, “music.mp3”);
music.play();
}

void draw() {

}

Hello,

Take a look at the example in the reference:
https://processing.org/reference/libraries/sound/SoundFile.html

Do you have a sound file in the correct folder and using the correct name?

Explore the menu and look for "Show Sketch Folder:

There is a mention in here of NullPointerException:

The guidelines in the Processing FAQ ask:

Please help us help you by formatting your code on this forum. Formatted code is not only easier to read, it sometimes cannot be cut-pasted and run correctly if not formatted, making it difficult for others to help you.
