java - How would I extract a specific row in a .CSV file? -

the goal of code ask user input, user specifies input , code search , find out row user input located.

once located, have code extract row (string array?) can edit part of it's contents.

my problem i'm not sure code/methods/classes use in order this.

i have code set right reads .csv file , outputs string array of type list. iterate through array , find out if user input specified located within file.

at moment, code says if found, unsure how extract specific row, , hoping guys me out.

here's code @ click of button:

try{          string strsearch = searchserialfield.gettext();          csvreader reader = new csvreader(new filereader("test.txt"), ',');         list<string[]> myentries = reader.readall();         reader.close();          //write existing file         //csvwriter writer = new csvwriter(new filewriter("test.txt"), ',',csvwriter.no_quote_character, "\r\n");          //iterate through array find row user input located on         (string[] line : myentries)         {             arraylist<string> newline = new arraylist<string>();             (string word : line)             {                 if (word.contains(strsearch))                 {                     //need method can find out row item on                     system.out.println("found - item on row: ...");                      //code extract row (string array?) can edit it's contents                      //i need write edited row it's original row                  }else                 {                     system.out.println("not found");                 }             }         }     }catch (ioexception e)         {             system.out.println(e);         } 

i've tried best i'm stumped how i'm meant extract row, how can go doing this?

thanks help.

what need not nested loop, arrays.tostring method.

import java.io.filereader; import java.io.ioexception; import java.util.arrays; import java.util.list;  import com.opencsv.csvreader;   public class test {     public static void main(string[] arg){         search();     }     public static void search(){         try{              string strsearch = "banana";              csvreader reader = new csvreader(new filereader("d:\\textfile.txt"), ',');             list<string[]> myentries = reader.readall();             system.out.println(myentries.size());             reader.close();              //write existing file             //csvwriter writer = new csvwriter(new filewriter("test.txt"), ',',csvwriter.no_quote_character, "\r\n");              //iterate through array find row user input located on             int i=1;             (string[] line : myentries)             {                  string textline = arrays.tostring(line).replaceall("\\[|\\]","");                 system.out.println(textline);                   if (textline.contains(strsearch))                     {                         //need method can find out row item on                         system.out.println("found - item on row: ...:"+i);                          //code extract row (string array?) can edit it's contents                          //i need write edited row it's original row                      }else                     {                         system.out.println("not found");                     }                   i++;             }         }catch (ioexception e)             {                 system.out.println(e);             }     } }
