finance - MACD java Double array -

i little stuck on how implement importing of closing price of ford. currently, using scanner while there next line should continue loop down. after importing line need converted double. question how can import entire file string array , convert double , use loop cycle through double array compute macd given equations.

import java.io.file; import java.io.filenotfoundexception; import java.util.scanner;  public class importcsv { public static void main(string[] args) {   //to import .csv file   string filename = "ford.csv";   file file = new file(filename);    try   {      scanner inputstream = new scanner(file);       //ignore first line      inputstream.next();       while (inputstream.hasnext())      {         //get whole line         string data = inputstream.next();          //split string array of strings         string [] values = data.split(",");          //convert double         double closingprice = double.parsedouble(values[4]);        // system.out.println(closingprice);          final double ema_12_alpha = 2.0 / (1 + 12);         final double ema_26_alpha = 2.0 / (1 + 26);         double ema12 = 0;         double ema26 = 0;         double macd = 0;               ema12 = ema_12_alpha * closingprice + (1 - ema_12_alpha) * ema12;            ema26 = ema_26_alpha * closingprice + (1 - ema_26_alpha) * ema26;            macd = ema12 - ema26;             system.out.println(macd);         }      inputstream.close();   }   catch (filenotfoundexception e)   {      // todo auto-generated catch block      e.printstacktrace();   } 

} }

file reading code has been omitted brevity - replace loop adding prices list while loop reading closing price csv.
