I am trying to read a file placed in the resources folder in my java project. I went trough many topics how to handle that but I cannot succeed coming up with NullPointerException. Could you please help me?

I have already tried many versions of code and this is the latest snippet that also fails:

BufferedReader br = new BufferedReader(new InputStreamReader(this.getClass().getClassLoader().getResourceAsStream("/small.in")))

Use the absolute path `input/small.in`. – Samuel Philipp Apr 29 '19 at 18:15
@SamuelPhilipp I have tried that as well and did not succeed – supercolo Apr 29 '19 at 18:16

@supercolo Did you try `getResourceAsStream("input/small.in")` – Jeeppp Apr 29 '19 at 18:18

@supercolo without `/` at the beginning. – Samuel Philipp Apr 29 '19 at 18:19
Thought I did, but eventually I did not! So it works now. Thank you! – supercolo Apr 29 '19 at 18:21
Which class is loading the resource? Where is this class? – Cardinal System Apr 29 '19 at 19:58
@CardinalSystem The class is in the src/main/java/service directory – supercolo Apr 29 '19 at 20:55
