Java arraylist how to read DDE double values from an excel file and write into an array? -

-

i have excel file dde links external sources. trying read values java application.

i using apache poi library read excel. when trying, following error:

exception in thread "main" java.lang.illegalstateexception: cannot numeric value text cell @ org.apache.poi.hssf.usermodel.hssfcell.typemismatch(hssfcell.java:643) @ org.apache.poi.hssf.usermodel.hssfcell.getnumericcellvalue(hssfcell.java:668) @ basketexcelread.run(basketexcelread.java:40) @ tester.main(tester.java:7)

my code is

import java.io.file; import java.io.fileinputstream; import java.io.ioexception; import java.util.arraylist; import java.util.list;  import org.apache.poi.hssf.usermodel.hssfcell; import org.apache.poi.hssf.usermodel.hssfrow; import org.apache.poi.hssf.usermodel.hssfsheet; import org.apache.poi.hssf.usermodel.hssfworkbook;  public class basketexcelread implements runnable {      public void run() {          string inputfile = "someexcel.xls";          list<string> code = new arraylist<string>();         list<double> bid = new arraylist<double>();         list<double> share = new arraylist<double>();          try {              fileinputstream file = new fileinputstream(new file(inputfile));              hssfworkbook workbook = new hssfworkbook(file);              hssfsheet sheet = workbook.getsheetat(0);              int ss = sheet.getphysicalnumberofrows();              (int = 0; < ss; i++) {                  hssfrow row = sheet.getrow(i);                 hssfcell cellcode = row.getcell(0);                 hssfcell cellbid = row.getcell(7);                 hssfcell cellshare = row.getcell(9);                  code.add(cellcode.getstringcellvalue());                 bid.add(cellbid.getnumericcellvalue());                 share.add(cellshare.getnumericcellvalue());              }          } catch (ioexception e) {             e.printstacktrace();         } {             system.out.println("done reading");         }           (int = 0; < 30; i++) {             system.out.println(code.get(i)+" "+bid.get(i)+" "+share.get(i));         }      } }

the cell text/numeric value conflict happens @ bid.add(cellbid.getnumericcellvalue()); cellbid dde link within excel file shows numeric values
