public class POICJ {
public static void main(String[] args) {
//创建一个数组,存放数据
String[] title = {"id","name","sex"};
//创建excel工作簿
XSSFWorkbook workbook = new XSSFWorkbook();
//创建一个工作表sheet
Sheet sheet = workbook.createSheet();
//创建第一行,从0开始
Row row = sheet.createRow(0);
//定义cell
Cell cell = null ;
//插入第一行数据, id ,name , sex
for (int i =0; i<title.length; i++){
cell = row.createCell(i);
cell.setCellValue(title[i]);
}
//追加数据
for ( int i=1; i<10; i++){
Row nextrow =sheet.createRow(i);
Cell cell2 =nextrow.createCell(0);
cell2.setCellValue("a"+i);
cell2 = nextrow.createCell(1);
cell2.setCellValue("user"+i);
cell2 = nextrow.createCell(2);
cell2.setCellValue("女生");
}
//创建一个文件
File file = new File("d:/poi_xlh_test.xlsx");
try {
file.createNewFile();
//将excel内容存盘
FileOutputStream stream = FileUtils.openOutputStream(file);
workbook.write(stream);
stream.close();
} catch (IOException e) {
e.printStackTrace();
}
}
