在Java中的jar文件中使用getResourceAsStream的最佳方法

Question

My jar file can't find my data.txt file with the code below:

try (BufferedReader br = new BufferedReader(new FileReader("data.txt"))) {
}

So I am trying to use getResourceAsStream . What is the best way to use it that does exactly the same as my code above? This is how my files are stored:

-Project
   -src
      -a.java
      -b.jav
   -data.txt

You can try something like:

String sFileName = "/data.txt";
String sFileToRead = getClass().getResource().getFile(sFileName);
BufferedReader br = new BufferedReader(new FileReader(new File(sFileToRead)));
