从java POI创建excel文件时出错

嗨，我想从java代码创建一个excel文件，我把这个代码放在eclipse上但没有任何反应

import org.apache.poi.ss.usermodel.Workbook; import org.apache.poi.hssf.usermodel.HSSFWorkbook; import java.io.FileOutputStream; public class TestPOI1 { public static void main(String[] args) { //create the new workbook Workbook workbook = new HSSFWorkbook(); try { //create the output stream to save the document on the hard drive FileOutputStream output = new FileOutputStream("Test1.xls"); //write the file onto the hard drive workbook.write(output); //finish it up by closing the document output.close(); } catch(Exception e) { e.printStackTrace(); } } } 

在控制台中，写入此消息

  Usage: BiffDrawingToXml [options] inputWorkbook Options: -exclude-workbook exclude workbook-level records -sheet-indexes output sheets with specified indexes -sheet-namek output sheets with specified name 

我无法在硬盘驱动器或文件项目中找到我的excel文件。 感谢帮助。
