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()) {

        } 

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);
