    Default Number format Exception


    Actually a situation is like i have a form in index.jsp file as :
    Number format Exception-index.png

    and i have another file as newcard.jsp which looks like :
    Number format Exception-newcard.png

    ok when i enter the mob no = 0123456789 OR 0987654321 , it works fine

    but when i'm trying to enter no. like mob no =9876543210 OR 9927080800 OR 8877009944 , it throws an exception on newcard.jsp as :

    org.apache.jasper.JasperException: java.lang.NumberFormatException: For input string: "8877009944"

    i'm really confused what to do as exactly don't know where i'm going wrong...

    so please help me with a solution and explaination

    thanks in advance

    What is the maximum size of an int?
    (Hint, it's less than the number you are trying to parse).

    Also, a phone number is not an int.
    It's a String that just happens to consist solely of digits.
    For example:
    might be a valid phone number, but if you converted that to an int you would get:
    which is not the same.

    ETA: Actually, just thought I'd add, it can also consist of a leading '+', if you're storing international dialling.
