用java写Excel

 

 

import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;

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;



public class WriteExcel {
     public static void main(String[] args) {
        FileOutputStream fos;
        try {
            fos = new FileOutputStream("d:\\test.xls");//文件要写的路径，如存在则覆盖，不存在则创建
            HSSFWorkbook wb = new HSSFWorkbook();
            HSSFSheet s = wb.createSheet();
            wb.setSheetName(0, "first sheet");
            for(int i=0;i<8;i++){
                HSSFRow row = s.createRow(i);
                for(int j=0;j<8;j++){
                    HSSFCell cell = row.createCell(j);

                    cell.setCellValue(i+","+j);
                }

            }

            wb.write(fos);
            fos.close();
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        } catch (IOException e) {
