import data from excel files to database

[efi oikonom]

Hi to all,
i am newbie in java. I have created a program to read data from excel files with APACHE POI and show them in my console. I am using Eclipse as editor. Now I an trying to import these data in database so I can store them. The purpose for that is i would like to be able to access them from different locations.
Can someone help me of how I would do this?

Here is my code for import data from excel to database:

import java.io.FileInputStream;
import java.io.IOException;
import java.sql.DriverManager;
import java.sql.SQLException;

import org.apache.poi.hssf.usermodel.HSSFSheet;
import org.apache.poi.hssf.usermodel.HSSFWorkbook;
import org.apache.poi.poifs.filesystem.POIFSFileSystem;
import org.apache.poi.ss.usermodel.Row;

import com.mysql.jdbc.Connection;
import com.mysql.jdbc.PreparedStatement;


public class EXCELTODB {

   
    public static void main(String[] args) {
        try{
            Class.forName("com.mysql.jdbc.Driver");
            Connection con = (Connection) DriverManager.getConnection("jdbc:mysql://localhost/test","root","");
            con.setAutoCommit(false);
            PreparedStatement pstm = null ;
            FileInputStream input = new FileInputStream("C:\\Users\\Efi\\Documents\\test5.xls");
            POIFSFileSystem fs = new POIFSFileSystem( input );
            HSSFWorkbook wb = new HSSFWorkbook(fs);
            HSSFSheet sheet = wb.getSheetAt(0);
            Row row;
            for(int i=1; i<=sheet.getLastRowNum(); i++){
                row = sheet.getRow(i);
                int id = (int) row.getCell(0).getNumericCellValue();
                String name = row.getCell(1).getStringCellValue();
                String address = row.getCell(2).getStringCellValue();
                String sql = "INSERT INTO tablename VALUES('"+id+"','"+name+"','"+salary+"')";
                pstm = (PreparedStatement) con.prepareStatement(sql);
                pstm.execute();
                System.out.println("Import rows "+i);
            }
            con.commit();
            pstm.close();
            con.close();
            input.close();
            System.out.println("Success import excel to mysql table");
        }catch(ClassNotFoundException e){
            System.out.println(e);
        }catch(SQLException ex){
            System.out.println(ex);
        }catch(IOException ioe){
            System.out.println(ioe);
        }

    }

And here is my code to read excel file using APACHE POI:

import java.io.FileInputStream;
import java.io.IOException;
import java.util.ArrayList;
import java.util.Iterator;
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;
import org.apache.poi.ss.usermodel.Cell;

public class ExcelRead{

public static void main(String[] args) throws Exception {
//
// An excel file name. You can create a file name with a full
// path information.
//
String filename = "C:\\Users\\Efi\\Documents\\test5.xls";

//
// Create an ArrayList to store the data read from excel sheet.
//
List sheetData = new ArrayList();

FileInputStream fis = null;
try {
//
// Create a FileInputStream that will be use to read the
// excel file.
//
fis = new FileInputStream(filename);

//
// Create an excel workbook from the file system.
//
HSSFWorkbook workbook = new HSSFWorkbook(fis);
//
// Get the first sheet on the workbook.
//
HSSFSheet sheet = workbook.getSheetAt(0);

//
// When we have a sheet object in hand we can iterator on
// each sheet's rows and on each row's cells. We store the
// data read on an ArrayList so that we can printed the
// content of the excel to the console.
//
Iterator rows = sheet.rowIterator();
while (rows.hasNext()) {
HSSFRow row = (HSSFRow) rows.next();
Iterator cells = row.cellIterator();

List data = new ArrayList();
while (cells.hasNext()) {
HSSFCell cell = (HSSFCell) cells.next();
data.add(cell);
}

sheetData.add(data);
}
} catch (IOException e) {
e.printStackTrace();
} finally {
if (fis != null) {
fis.close();
}
}

showExelData(sheetData);
}

private static void showExelData(List sheetData) {
//
// Iterates the data and print it out to the console.
//
for (int i = 0; i < sheetData.size(); i++) {
List list = (List) sheetData.get(i);
for (int j = 0; j < list.size(); j++) {
Cell cell = (Cell) list.get(j);
if (cell.getCellType() == Cell.CELL_TYPE_NUMERIC) {
System.out.print(cell.getNumericCellValue());
} else if (cell.getCellType() == Cell.CELL_TYPE_STRING) {
System.out.print(cell.getRichStringCellValue());
} else if (cell.getCellType() == Cell.CELL_TYPE_BOOLEAN) {
System.out.print(cell.getBooleanCellValue());
}
if (j < list.size() - 1) {
System.out.print(", ");
}
}
System.out.println("");
}
}
}

Welcome to the Ranch
I have added code tags, which you should always use. You can see how much better it looks, at least where you actually indented the code:wink:
