Convert word to a sum of integer representation of characters

Question

I'm trying to convert a word such as foo to a sum of the integer encoding of individual characters. This would be calculated as 102 + 111 + 111 equaling 324. I'm trying to achieve this using a stream from a list of characters:

String word = "foo";

Arrays
   .asList(word.toCharArray())
   .stream()
   .mapToInt (letter -> Character.getNumericValue(letter))
   .sum();

The error I'm getting is:

no suitable method found for getNumericValue(char[])

How would I go about resolving this error, or is there a better way to accomplish this?

Answer 1

Use the official way, and not some kind of "I want a Stream, but I can only get a Stream from a List, so I have to convert the String into a List".

String word = "foo";

word.codePoints().sum()

String.codePoints() returns an IntStream of the code points in the stream.
Note that not every character can be represented by a single char , emojis for example need two char s.

Answer 2

      int sum = word.chars().sum();
      System.out.println(sum);
