Thread: regular expression issue

    Default regular expression issue

    I use the method String.matches(String regex) to find if a string matches the regex expression

    From my point of view the regular expression regex="[0-9]+" means a String that contains at least one figure between 0 and 9

    But when I debug "3.5".matches("[0-9]+") it returns false.

    So what is wrong ?

    Perhaps your point of view is obscured? Did you look into String.matches and see if it does what you think?
    Have you looked at the Pattern class?
    Have you tried to figure out if anything else would work? For example if you changed "3.5" to "3", would it then return true?
