如何利用JAVA生成Excel文件

Answer 1

package beans.excel;

import java.io.IOException;
import java.io.OutputStream;

import jxl.Workbook;
import jxl.write.Label;
import jxl.write.WritableSheet;
import jxl.write.WritableWorkbook;
import jxl.write.WriteException;

public class SimpleExcelWrite {
public void createExcel(OutputStream os) throws WriteException,IOException{
//创建工作薄
WritableWorkbook workbook = Workbook.createWorkbook(os);
//创建新的一页
WritableSheet sheet = workbook.createSheet("First Sheet",0);
//创建要显示的内容,创建一个单元格，第一个参数为列坐标，第二个参数为行坐标，第三个参数为内容
Label xuexiao = new Label(0,0,"学校");
sheet.addCell(xuexiao);
Label zhuanye = new Label(1,0,"专业");
sheet.addCell(zhuanye);
Label jingzhengli = new Label(2,0,"专业竞争力");
sheet.addCell(jingzhengli);

Label qinghua = new Label(0,1,"清华大学");
sheet.addCell(qinghua);
Label jisuanji = new Label(1,1,"计算机专业");
sheet.addCell(jisuanji);
Label gao = new Label(2,1,"高");
sheet.addCell(gao);

Label beida = new Label(0,2,"北京大学");
sheet.addCell(beida);
Label falv = new Label(1,2,"法律专业");
sheet.addCell(falv);
Label zhong = new Label(2,2,"中");
sheet.addCell(zhong);

Label ligong = new Label(0,3,"北京理工大学");
sheet.addCell(ligong);
Label hangkong = new Label(1,3,"航空专业");
sheet.addCell(hangkong);
Label di = new Label(2,3,"低");
sheet.addCell(di);

//把创建的内容写入到输出流中，并关闭输出流
workbook.write();
workbook.close();
os.close();
}

}
