线程＆＃34; main＆＃34;中的例外情况java.io.FileNotFoundException :. xls（系统找不到指定的文件）

Question

我试图从excel文件中读取数据，但控制台提供了系统无法找到指定路径的异常。但我已经给出了正确的路径，文件也是可访问的。请帮我解决这个问题。

WebDriver driver = new FirefoxDriver();
driver.get("someurl");

Workbook book = Workbook.getWorkbook(new File("E:\\TestDataforSelenium1.xls"));
Sheet sh= book.getSheet("TestData");
for(int i=0; i<sh.getRows(); i++)
{
    String username=sh.getCell(0, i).getContents();
    String password=sh.getCell(1, i).getContents();
    driver.findElement(ByName.name("uid")).sendKeys(username);          
    driver.findElement(ByName.name("password")).sendKeys(password);         
    driver.findElement(ByName.name("btnLogin")).click();
    try
    {
        Alert alt=driver.switchTo().alert();        
        String alerttext=alt.getText(); 
        System.out.println(alerttext);
        if(alerttext.equalsIgnoreCase("User or Password is not valid"))
        {
            alt.accept();
            System.out.println("test case pass with invalid credential and valid error message");   
        }
        else        
            System.out.println("test case pass with invalid credential");   
        }           
    catch (NoAlertPresentException Ex)      
    {       
        String url ="http://www.demo.guru99.com/V4/manager/Managerhomepage.php";    
        if (url.equalsIgnoreCase("http://www.demo.guru99.com/V4/manager/Managerhomepage.php"))  
            System.out.println("Verify that user is successfully able to login.");
        else    
        System.out.println("Verify that user is not able to log into the application.");
    }
}
