NumberUtils.isParsable介绍

[英]Checks whether the given String is a parsable number.

Parsable numbers include those Strings understood by Integer#parseInt(String), Long#parseLong(String), Float#parseFloat(String) or Double#parseDouble(String). This method can be used instead of catching java.text.ParseExceptionwhen calling one of those methods.

Hexadecimal and scientific notations are not considered parsable. See #isCreatable(String) on those cases.

Null and empty String will return false.
