How to convert CSVRecord to List?

Question

I need to convert a CSVRecord to a List to get the position of an element.

So I used this:

List<CSVRecord> records = csvParser.getRecords();
int i = records.get(0).indexOf(element);

However, records.get(0) returns a List<CSVRecord> and not a List<String> ...

Moreover I cannot use csvParser.getHeaderNames(); because after that I need to copy the file with the header.

Answer 1

Given the below function that I found on geeksforgeeks.com

public static <T> List<T> getListFromIterator(Iterator<T> iterator) { 
    Iterable<T> iterable = () -> iterator; 

    return StreamSupport 
              .stream(iterable.spliterator(), false) 
              .collect(Collectors.toList()); 
} 

and the fact that you can get an iterator from CVSRecords you can do

List<String> list = getListFromIterator(records.get(0).iterator());
