Selenium 写入excel文件

}

使用Jxl获取Excel文件中的行

public class ExcelLibrary{

请指定您想做什么，并正确设置问题格式。不可能读懂你的问题！这甚至不是一个问题！添加到评论中是否有使用jxl的特定原因？因为这个API有很多限制，所以最好使用ApachePOIAPI。

package Testpackage;

import java.io.FileInputStream;
import java.io.IOException;
import jxl.Workbook;
import jxl.Sheet;
import jxl.read.biff.BiffException;

public class Rowcount {
    public static void main(String[] args) throws BiffException, IOException {
        FileInputStream exo=new FileInputStream("E:\\test1.xls");
        Workbook wbo=Workbook.getWorkbook(exo);
        Sheet wso=wbo.getSheet(0);
        int lastrownum;
        lastrownum= wso.getRows();
        System.out.println(lastrownum);
    }
