import java.io.IOException;
import java.util.Random;
/*poi*/
import org.apache.poi.hssf.usermodel.HSSFCell;
import org.apache.poi.hssf.usermodel.HSSFRichTextString;
import org.apache.poi.hssf.usermodel.HSSFRow;
import org.apache.poi.hssf.usermodel.HSSFSheet;
import org.apache.poi.hssf.usermodel.HSSFWorkbook;

public class ExcelExporting {

public int int1;
public int writeExcelFile(String fileName) {
FileOutputStream fileOutputStream = null;
HSSFWorkbook sampleWorkbook = null;
HSSFSheet sampleDataSheet = null;
try {


sampleWorkbook = new HSSFWorkbook();
sampleDataSheet = sampleWorkbook.createSheet();

HSSFRow headerRow = sampleDataSheet.createRow(0);
HSSFRow dataRow1 = sampleDataSheet.createRow(1);

Random randomGenerator = new Random();
int1=randomGenerator.nextInt(9000000)+1000000;
System.out.println("Number is:"+ int1);

HSSFCell firstHeaderCell = headerRow.createCell(0);

firstHeaderCell.setCellValue(new HSSFRichTextString("RN"));

dataRow1.createCell(0).setCellValue(
new HSSFRichTextString(""+int1));
fileOutputStream = new FileOutputStream(fileName);
sampleWorkbook.write(fileOutputStream);
} catch (Exception ex) {
System.out.println(ex);
} finally {

try {
if (fileOutputStream != null) {
fileOutputStream.close();
}
} catch (IOException ex) {
System.out.println(ex);
}
}
return int1;
}

public static int Export(){
int int2 = new ExcelExporting().writeExcelFile("G:\\Excel\\Excel2.xls"); /*this method will return int1 value and we are assigning to int2 */
return int2;
}

}


This might help u....

hey i tried your code in eclipse but it gives error saying HSSFWorkbook,HSSFSheet, HSSFRow,HSSFCell, HSSFRichTextString do cannot be resolved to a type and the available fixes ask for creating a class of the respective type........................do i need to import some file or declare any variable?

yes u need to add poi jar for tht....

k.....thanks...can you tell me a link to download these jar files?
