NumberUtils.isCreatable介绍

[英]Checks whether the String a valid Java number.

Valid numbers include hexadecimal marked with the 0x or 0X qualifier, octal numbers, scientific notation and numbers marked with a type qualifier (e.g. 123L).

Non-hexadecimal strings beginning with a leading zero are treated as octal values. Thus the string 09 will return false, since 9 is not a valid octal value. However, numbers beginning with 0. are treated as decimal.

null and empty/blank String will return false.

Note, #createNumber(String) should return a number for every input resulting in true.
[中]检查字符串是否为有效的Java数字。
有效数字包括用0x或0X限定符标记的十六进制数字、八进制数字、科学记数法和用类型限定符标记的数字（例如123L）。
以前导零开头的非十六进制字符串被视为八进制值。因此字符串09将返回false，因为9不是有效的八进制值。但是，数字以0开头。被视为十进制。
null和空/空字符串将返回false。
注意，#createNumber（String）应该为每个导致true的输入返回一个数字。
