Read CSV files in Java using Apache Commons CSV for loop starting index 1

Question

I have the following Code about iterating over a list of elements in a CSV file.

 for (CSVRecord csvRecord : csvParser) {
    // Accessing Values by Column Index
    String name = csvRecord.get(0);

    dates_csv.add(name);
  }

}

How can I start the iteration starting from Index 1 in this for loop. I am still new to java :)

Use a regular index-based for loop instead of the current foreach one you're using? — Gagravarr

boolean firstRound = true;
for (CSVRecord csvRecord : csvParser) {
    if(firstRound){
        firstRound = false;
    } else {
        String name = csvRecord.get(0);
        dates_csv.add(name);
    }
}

or

List<CSVRecord> recList = csvParser.getRecords();
for(int i = 1; i < recList.size(); i++){
    dates_csv.add(recList.get(i).get(0));
}

List<CSVRecord> parserList = parser.getRecords();
for (CSVRecord csvRecord : parserList.subList(1, parserList.size()))
{ 
    //code here
}

How will you get subList from an Iterable?

List<CSVRecord> parserList = parser.getRecords();

for (CSVRecord csvRecord : parserList.subList(1, parserList.size())) { //code here } }
