Find String Values of Cell Using POI

     

In this program we are going to find the String Values of Cell of  an excel sheet using POI3.0 API Event.

The class  org.apache.poi.hssf.record.LabelSSTRecord extends Record implements CellValueRecord interface and java.lang.Comparable
This is used  to make reference of a string  and a column value. 

The methods used in this example:

getSSTIndex():
The method is used to get the index to the string in the SSTRecord. The return type of this method is integer (index of string in the SST Table).

getString(int i):
This method is used to get the string  value from SSTRecord .

The code of the program is given below:
import java.io.*;
import org.apache.poi.hssf.usermodel.*;
import org.apache.poi.poifs.filesystem.*;
import org.apache.poi.hssf.usermodel.HSSFRow;
import org.apache.poi.hssf.eventusermodel.*;
import org.apache.poi.hssf.record.*;
import org.apache.poi.hssf.dev.EFHSSF;
public class FindStringCellsValues implements HSSFListener
{
 public static void main(String[] argsthrows IOException
  {
 FileInputStream fin = new FileInputStream(args[0]);
 
  POIFSFileSystem poifs = new POIFSFileSystem(fin);
  InputStream din = poifs.createDocumentInputStream
(
"Workbook");
  HSSFRequest req = new HSSFRequest();
 req.addListenerForAllRecords
(
new FindStringCellsValues());
 HSSFEventFactory factory = new HSSFEventFactory();
  factory.processEvents(req, din);
  fin.close();
 din.close();
  System.out.println("STOP");
  }
  SSTRecord sstrecord;
  public void processRecord(Record record)
  {
  switch (record.getSid()) {
  case SSTRecord.sid:
  sstrecord = (SSTRecordrecord;
  for (int k = 0; k < sstrecord.
getNumUniqueStrings
(); k++)
  {
  System.out.println("String 
table value " 
+ k + " = " + sstrecord.getString(k));
  }
  System.out.println("\n\n");
  break;
  
  case LabelSSTRecord.sid:
  LabelSSTRecord lrecord = (LabelSSTRecordrecord;
  System.out.println("String cell found with value \t"
  + sstrecord.getString(lrecord.getSSTIndex()));
  break;
  }
 }  
}

The output of the program is given below:
