If you are trying to convert String to Number.如果您尝试将字符串转换为数字。 In the above case I think your String is "8/3/2012".在上述情况下,我认为您的字符串是“8/3/2012”。 For converting to any number, you must not have any characters other than numbers or you can have double if you want decimals.要转换为任何数字,您不能有数字以外的任何字符,或者如果您想要小数,则可以有 double。
This looks like a date, please explore the Date class and see how you can convert it to a date.这看起来像一个日期,请浏览 Date 类,看看如何将其转换为日期。
Date 8/3/2012 is not proper numeric type.日期 8/3/2012 不是正确的数字类型。 Check the line of code where you are parsing it to Double.检查将其解析为 Double 的代码行。
From the java docs,从java文档,
Thrown to indicate that the application has attempted to convert a string to one of the numeric types, but that the string does not have the appropriate format.抛出以指示应用程序已尝试将字符串转换为数字类型之一,但该字符串没有适当的格式。
