csv

问题 I have a CSV file where columns are comma separated and columns with textual data that have commas are quoted. Sometimes, within quoted text there also exist quotes to mean things like inches resulting in more quotes. Textual data without embedded commas do not have quotes. For example: A,B,C 1,"hello, how are you",hello 2,car,bike 3,13.3 inch tv,"tv 13.3""" How do i use awk to print the number of columns for each row of which i should get 3 3 3 I thought of using $awk -F'[,"]' but im getting

Filenames are: AP.csv (list of APs, headers are Hostname and IP): Hostname;IP AP1;10.29.202.101 AP2;10.29.202.102 AP3;10.29.202.103 AP4;10.29.202.104 Ap5;10.29

问题 I have a CSV file like so - "user_id","age","liked_ad","location" 2145,34,true,USA 6786,25,true,UK 9025,21,false,USA 1145,40,false,UK The csv file goes on. I worked out that there are duplicate user_id's within the file and so what I am trying to do is find out which users have the most 'true' answers for the 'liked_ads' column. I am super stuck on how to do this in Java and would appreciate any help. This is what I have so far to literally just parse the file - public static void main(String
