Java - 转换文件名 - 出错？

Question

(这里是Hello world级别的自动化测试人员)

我正在尝试下载一个文件并将其重命名以便于查找。我收到一个错误....这是代码

    @Test
public void allDownload() throws Exception {
    PiDownloadScreen();
    WebElement oK = driver.findElement(By.xpath
            ("/html/body/div[4]/div[11]/div/button"));
    String timeStamp = new SimpleDateFormat("yyyyMMddHHmmss").format(Calendar.getInstance().getTime());
    oK.click();
    System.out.println(timeStamp);
    File fileName = new File("C:/Users/HIQMD017/Downloads/" + timeStamp + (".csv"));
    File newName = new File("C:/Users/HIQMD017/Downloads/allPI.csv");
    if (fileName.renameTo(newName)) {
        System.out.println("AllPI was renamed");
    }
    else
    {
        int timeStampInt = Integer.parseInt(timeStamp);
        int completeStamp = timeStampInt - 1;
        String completeString = Integer.toString(completeStamp);
        File fileNameNew = new File("C:/Users/HIQMD017/Downloads/" + completeString + (".csv"));
        fileNameNew.renameTo(newName);
        System.out.println("All pi was renamed after conversion");
    }
    System.out.println(completeString);
}

我不确定为什么会收到这些错误以及它们的含义，我对调试器也不是很擅长，有人可以提供一些见解吗，我查看了我的代码，看起来还不错，哈dto 说我哪里出错了。如果需要，我很乐意添加其他代码，当然我需要修改以保密。

亲切的问候，

Answer 1

您使用的字符串(时间戳)超出整数范围。这就是它抛出 NumberFormatException 的原因。您可以替换以下代码:

 int timeStampInt = Integer.parseInt(timeStamp);
 int completeStamp = timeStampInt - 1;
 String completeString = Integer.toString(completeStamp);

作者:

long timeStampLong = Long.parseLong(timeStamp);
long completeStamp = timeStampLong - 1;
String completeString = Long.toString(completeStamp);

我认为这会奏效。
