Java: List how to get specific element on a line

Question

I'm trying to get a specific element from a list, but not the entire list. For example if I do

System.out.println(words.get(0))

I would get

[16, Matthew, 13,954, Alexis, 8,181]

But how would I get a specific element on this line, like the name Matthew and not the whole line. [Matthew]

 List<List<String>> words = topNames.stream()
                .map(sentence -> sentence.split("\\s+"))
                .map(Arrays::asList)
                .collect(Collectors.toList());


            System.out.println(words.get(0));

Answer 1

Add a map() operation to map to the elements at the specified index :

 List<String> wordsAtTheOneIndex = topNames.stream()
                .map(sentence -> sentence.split("\\s+"))
                .map(Arrays::asList)
                .map(l -> l.get(1))
                .collect(Collectors.toList());
