the project need create the Excel files.i try to use MS Lib in .net but it cost a lot of menory.so i get the JexcelApi and POI to create excel file,it is great.

this page is keep code,nothing else,:>

this is the process Class:

package jExcel;

import jxl.*;

import jxl.write.*;

import jxl.write.biff.RowsExceededException;

import java.io.*;

import java.util.*;

public class Export {

/**

* Data Items

*/

private static List<String[]> items = new ArrayList<String[]>();

/**

* Generate Items

*

* @param Address

* @param Zip

*/

public static void GenerateItem(String Address, String Zip) {

items.add(new String[]{Address,Zip});

}

/**

* Export To Excel

*

* @param filepath

* @throws IOException

* @throws RowsExceededException

* @throws WriteException

*/

public static void ExportToExcel(String filepath) throws IOException,

RowsExceededException, WriteException {

File file = new File(filepath);

//check file exsist

if (file.exists()) {

} else {

file.createNewFile();

}

//create create a workbook

WritableWorkbook book = Workbook.createWorkbook(file);

//create a sheet

WritableSheet sheet = book.createSheet("sheet1", 0);

//init a new label

Label label = null;

/**

* create head line

*/

//create a new label

label = new Label(0, 0, "Address");

//add label into sheet

sheet.addCell(label);

//TODO:you can add cell format here like:WritableCellFormat

label = new Label(1, 0, "Zip");

sheet.addCell(label);

//add item cells

for (int i = 0; i < items.size(); i++) {

String[] temp = items.get(i);

for (int s = 0; s < temp.length; s++) {

label = new Label(s,i + 1, temp[s]);

sheet.addCell(label);

}

}

//begin to write excel to disk

book.write();

//close this steam

book.close();

}

}

this is the main function class:

import java.io.*;

import java.util.*;

import jxl.write.WriteException;

import jxl.write.biff.RowsExceededException;

import jExcel.*;

public class ExApplication {

static String s = "";

static BufferedReader input = new BufferedReader(new InputStreamReader(

System.in));

static String getFilename() {

String temp = "";

File file = new File(".");

temp = file.getAbsolutePath().substring(0,

file.getAbsolutePath().lastIndexOf("\\"))

+ "\\";

Date day = new Date();

temp += day.toString().replace(" ", "").replace(":", "") + ".xls";

return temp;

}

/**

* @param args

* @throws IOException

* @throws WriteException

* @throws RowsExceededException

*/

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

RowsExceededException, WriteException {

System.out.println("Please input Address,Zip");

while (!s.toLowerCase().equals("done")) {

if (s.toLowerCase().indexOf(",") > -1) {

String[] temp = s.toLowerCase().split(",");

if (temp.length == 2) {

Export.GenerateItem(temp[0], temp[1]);

}

}

s = input.readLine();

}

if (s.toLowerCase().equals("done")) {

try {

String name = getFilename();

Export.ExportToExcel(name);

System.out.println("Create Complete File :" + name);

} catch (Exception ex) {

ex.printStackTrace();

}

}

}

}
