My regex does not remove the dash between numbers in java

I have tried to use regex in JAVA for replacing any funny character in a string for mobile numbers, however, it doesnt seems to be able to remove the '-' between the numbers

here is my code,

// Remove all (,),-,.,[,],<,>,{,} from string

myMobileNumber.replaceAll("[^\\d]", "");

example 65-12345678

it will still allows the - to go through without deleting it away. =(

You should reassign the result. A String is an immutable object, and all methods including .replaceAll won't modify it.

myMobileNumber = myMobileNumber.replaceAll("[^\\d]", "");

(BTW, the pattern "\\D" is equivalent to "[^\\d]".)
