Find Value of Column

In this program we are going to find the value of row from the column of an excel sheet using POI3.0 API Event.

The org.apache.poi.hssf.record.NumberRecord class extends Record and implements CellValueRecord interface, java.lang.Comparable interface.

The methods used in this example:

getRow():
This method is used to get the row from cell.

getColumn():
This method is used to get the column from cell defines within the row.

getNumStrings():
This method is used to fine the number of strings.

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 FindValuesRowAtColumn implements HSSFListener

{

 public static void main(String[] args) throws IOException

  {

  

  FileInputStream fin = new FileInputStream(args[0]);

 

  POIFSFileSystem poifs = new POIFSFileSystem(fin);

  InputStream din = poifs.createDocumentInputStream

    ("Workbook");

  HSSFRequest req = new HSSFRequest();

 req.addListenerForAllRecords(new 

    FindValuesRowAtColumn());

 HSSFEventFactory factory = new HSSFEventFactory();

  factory.processEvents(req, din);

  fin.close();

 din.close();

  System.out.println("STOP");

  }

  public void processRecord(Record record)

  {

  switch (record.getSid())  {

  

  case NumberRecord.sid:

  NumberRecord numrecord = (NumberRecord) 

    record;

  System.out.println("Cell found with value "

     + numrecord.getValue()

  + " at row " + numrecord.getRow() +

     " and column " + numrecord.getColumn());

  break;

  case SSTRecord.sid:

  SSTRecord sstrecord = (SSTRecord) record;

  for (int k = 0; k < sstrecord.

    getNumUniqueStrings(); k++)

  {

  System.out.println("String table value " + k + 

    " \t " + sstrecord.getString(k));

  }

  break;

  }

 }  

}

The output of the program is given below:
