equivalent to Files.readAllLines() for InputStream or Reader?

Question

I have a file that I\'ve been reading into a List via the following method:

List doc = java.nio.file.Files.readAllLines(new File(\"/path/to/src/res

An InputStream represents a stream of bytes. Those bytes don't necessarily form (text) content that can be read line by line.

If you know that the InputStream can be interpreted as text, you can wrap it in a InputStreamReader and use BufferedReader#lines() to consume it line by line.

try (InputStream resource = Example.class.getResourceAsStream("resource")) {
  List doc =
      new BufferedReader(new InputStreamReader(resource,
          StandardCharsets.UTF_8)).lines().collect(Collectors.toList());
}
