package com; import org.apache.poi.hssf.usermodel.*; import org.apache.poi.poifs.filesystem.POIFSFileSystem; import java.io.*; public class read { /** * @param args */ public static void main(String[] args) { // TODO Auto-generated method stub POIFSFileSystem fs = null; HSSFWorkbook wb = null; try { fs = new POIFSFileSystem(new FileInputStream("test.xls")); wb = new HSSFWorkbook(fs); } catch (IOException e) { e.printStackTrace(); } HSSFSheet sheet = wb.getSheetAt(0);//第一张表，注意这里和数组类似是从0开始数的 HSSFRow row = sheet.getRow(4); //第4行，同样也是从0开始数的 HSSFCell cell = row.getCell((short) 3);//第3列，同样也是从0开始数的 String msg = cell.getStringCellValue(); System.out.println(msg); } }
