    hello

    I want to validate a phone number
    the logic is as follows

    0 or 1 '+'

    followed by at least 6 digits and as many spaces in between

    so I had this expression
    [+]?\\s]*[\\d{6,}$
    so [+]? = + once or not at all
    and [\s]*[\d]{1} (lets call this A)= zero or more whitespace charaters followed by a 1 digit
    [A]{6,0} = A to be true at least 6 times

    but yet the phone number
    77 77 comes back as true
    even though I'm looking for 6 digits

    any body any clue of where my logic is wrong?

    Once regex sees square brackets it tries to match one of the items in the brackets, I think this is where your problem lies. Try this instead
    [+]?\\s*\\d{6,}$

    Doh! with the round brackets

    [+]?(\\s*\\d\\s*){6}$
