How to check that a string is parseable to a double? [duplicate]

Question

Is there a native way (preferably without implementing your own method) to check that a string is parseable with Double.parseDouble()?

Answer 1

Apache, as usual, has a good answer from Apache Commons-Lang in the form of NumberUtils.isCreatable(String).

Handles nulls, no try/catch block required.

Answer 2

You can always wrap Double.parseDouble() in a try catch block.

try {   Double.parseDouble(number); } catch(NumberFormatException e) {   //not a double }
