Answer 1

Your if statement compares a string to an integer thats why there is an error.
What is idPassportNum for i dont see it being used. And if you redefine contactNum to "contactNum" after the input why take in an input for it in the first place?
I think you're trying to do this

Answer 2

get the length then compare them with 10
contactNum.length() == 10
