文件.xslx中的第一项不是用java读取的

任何人都可以知道我在做什么错了吗？我创建一个数据库连接和数据（登录，密码）保存到File.xlsx的是什么文件写入文件.xslx中的第一项不是用java读取的

Login1 | Password1 
Login2 | Password2 
Login3 | Password3

然后，它从文件到测试检索值之后实施例。然而，测试开始从

Login2 | Password2 
Login3 | Passrowd3

虽然

Login1 | Password1

它从一个文件下载数据时省略下载数据。

有人能指导我哪里出错吗？我是初学者，对于丑陋的代码感到抱歉。

ReadData.java

public class ReadData {

    XSSFWorkbook wb = new XSSFWorkbook(pkg); 

    XSSFSheet s = wb.getSheet("EMP_DETAILS"); 

    Iterator<Row> rowIterator = s.iterator(); 
    rowIterator.next(); 

    ArrayList<String> list = new ArrayList<String>(); 
    while(rowIterator.hasNext()){ 
     list.add(rowIterator.next().getCell(colNo).getStringCellValue()); 
    } 
    System.out.println("List :::: "+list); 
    return list; 
} 

public void tc() throws IOException, InterruptedException, InvalidFormatException{ 
    WebDriver driver = new FirefoxDriver(); 
    driver.get("https://accounts.google.com/ServiceLogin?service=mail&passive=true&rm=false&continue=https://mail.google.com/mail/&ss=1&scc=1&ltmpl=default&ltmplcache=2&emr=1&osid=1#identifier"); 
    driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS); 
    driver.manage().window().maximize(); 

    ArrayList<String> userName = readExcelData(0); 
    ArrayList<String> password = readExcelData(1); 

    for(int i =0;i<userName.size();i++){ 
    // driver.findElement(By.id("f_login")).clear(); 
    driver.findElement(By.id("Email")).sendKeys(userName.get(i)); 
    driver.manage().timeouts().implicitlyWait(100, TimeUnit.SECONDS); 
    driver.findElement(By.id("next")).click();

    driver.findElement(By.id("Passwd")).sendKeys(password.get(i));

在你readExcelData方法，您在遍历文件的行之前调用rowIterator.next();：

Iterator<Row> rowIterator = s.iterator(); 
rowIterator.next();

那调用似乎是多余的，看起来会跳过第一行。所以尝试，删除第一个rowIterator.next();电话。
