六禕-POI創建Excel之2013版本

第一步：導入jar包

第二步：上代碼

package cn.lystudio.poi.excel;

import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;

import org.apache.commons.io.FileUtils;
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;

		//創建一個數組，存放數據
		String[] title = {"id","name","sex"};
		
		//創建excel工作蒲
		HSSFWorkbook workbook = new HSSFWorkbook();
