Answer 1

The given number must be within the int range otherwise you get this error.

Answer 2

Jigar Joshi has explained why you're getting the exception in the first place, but personally I'd avoid parsing the number that way to start with... you'll lose information about significant leading zeroes. For example, my home phone number in the UK starts with "0797" - if you try to dial it without the 0, it will fail.

Likewise "00" is often used as the equivalent of "+" to dial international numbers.

Basically, I'd store the number as a string instead of as an integer.

Answer 3

4342432435 is greater than the maximum value for a 32-bit int.

Answer 4

Because 4342432435 is out of int 's range., Use long field and Long.parseLong(someString);
