java - How to parse a String into multiple arrays -

good day!

i making mini bookstore program , required read file based customer buys on specified counter follows:

counter 4,book1 2,book2 2,book3 2,tender 100.00 counter 1,book1 2,book2 1,book3 3, book4 5,tender 200.00 counter 1,book3 1,tender 50.00 

in short format is: counter -> items bought -> tender

i tried doing not efficient:

public list<string> getorder(int i) {         list <string> tempqty = new arraylist<string>();         string[] orders = orderlist.get(0).split(",");         (string order : orders) {             string[] fields = order.split(" ");             tempqty.add(fields[i]);         }         return tempqty; } 

how can read file , @ same time, ensures put on correct array? besides counter , tender, need know name of book , qty price , computer total price. need multiple arrays store each values? suggestions/ codes highly appreciated.

thank you.

    map<string, integer> itemsbought = new hashmap<string, integer>();     final string counter = "counter";     final string tender = "tender";     string[] splitted = s.split(",");     (string str : splitted) {         str = str.trim();         if (str.startswith(counter)) {             //do want counter         } else if (str.startswith(tender)) {             //do want tender         } else {             //process items, e.g:             string[] iteminfo = str.split(" ");             itemsbought.put(iteminfo[0], integer.valueof(iteminfo[1]));         }     }
