I didn't see it documented, figured the easiest way to find out would be to
just test it.
It currently uses the last column with the given name.
> What happens/should happen for each enum value when you call
CSVRecord.get(String).
| A | A
|---|---
| 1 | 2
| 3 | 4
```java
List<CSVRecord> records = parser.getRecords();
for (CSVRecord record : records)
System.out.println(record.get("A"));
// 2
// 4
```
> What happens/should happen for each enum value when you call
CSVRecord.toMap().
| A | A | B | B
|---|---|---|---
| 1 | 2 | 5 | 6
| 3 | 4 | 7 | 8
```java
List<CSVRecord> records = parser.getRecords();
for (CSVRecord record : records) {
Map<String, String> map = record.toMap();
System.out.println(map);
}
// {A=2, B=6}
// {A=4, B=8}
```
I think we could add a docstring on `CSVRecord#get` and `CSVRecord#toMap` to
clarify this.
We could also add something on `CSVFormat#setDuplicateHeaderMode`?
It might be a good idea to add test cases to cover this scenario, if it'll
become documented behavior.
Mind if I do this in a separate PR?
I'd say it counts as a separate change from this one, so it'll keep things
tidier.
