I have a system where users can import data through csv files. The file is parsed to POJOs using SuperCSV.
I want to be able to manage these files with or without the header row.
CsvBeanReader.getHeader(true) will extract the first row, but if it is not a header then that row won't be parsed by the BeanReader.
Is there an easy way of detecting the header without losing the first line of data?
The best idea to skip header from super csv while reading the values from file:-
//dont write this line beanReader.getHeader(true)
// before reading the values pass headers array that u have declared like headers = {column1},{column2}
//then use below lines, which exclude the header
beanReader.read(type, headers, processors))
Above steps help us to read the csv file which was saved without header.
The easiest solution would be to just read the file twice (check for expected headers on the first pass - you only need to read the first line, and read with/without header on the second pass).
I found a solution.
By wrapping the provided Reader using a BufferedReader I could mark the beginning, read the first line, and then do reader.reset() if it's not the header.
