and your value is:
你的价值是：

You can't use a longfor this. You could use BigIntegerinstead, but given the use-case, I think that Stringwould be the most appropriate type. (I can't imagine you needingto do integer arithmetic on book ids, and if you need to do numeric comparison, you could easily implement a custom Comparator to do that on decimal strings.)
您不能long为此使用 a 。您可以BigInteger改用，但考虑到用例，我认为这String将是最合适的类型。（我无法想象您需要对书籍 ID 进行整数运算，如果您需要进行数字比较，您可以轻松实现自定义 Comparator 来对十进制字符串执行此操作。）

I think you need to use BigIntegeror BigDecimal
我认为您需要使用BigInteger或BigDecimal
For example:
例如：
BigInteger bi;
String buyId = "PSFT_20110328114728073793";
bi = new BigInteger(buyId.replaceAll("PSFT_",""));
Add try-catch block too, with NumberFormatException
也添加 try-catch 块，使用 NumberFormatException

What about using something suiting for storing timestamps more than just a long? Date class? or JodaTime? Probably this post also will be helpful: Joda time : How to convert String to LocalDate?
使用适合存储时间戳而不只是很长的东西怎么样？约会课？还是JodaTime？可能这篇文章也会有帮助：Joda time : How to convert String to LocalDate?

I don't think the label PSFT_20110328114728073793 was ever intended to be used arithmetically. It seems to be a combination of type, date and ID. As others have pointed out 20110328114728073793 won't fit in a long. Maybe splitting the string into its original parts would make more sense for your use case ?
我认为标签 PSFT_20110328114728073793 从来没有打算在算术上使用。它似乎是类型、日期和 ID 的组合。正如其他人指出的那样 20110328114728073793 不适合长时间使用。也许将字符串拆分为其原始部分对您的用例更有意义？

The number is out of Long range. Use BigInteger!
该号码超出了远程范围。使用大整数！
