Ned help please.

Question

How can I make it possible so the UserA “ Input” doesn’t enter number below 18 ? Or it only enter 4 digits ex: 1994?

Answer 1

Then your code works fine except that you are Notifying about DOB input, after accepting. Instead add line 23 , before DOB input.

If you want to validate input as 4 digits, then you can check like if dob is between 1000 and 9999 (possible 4 digits).. But you can cut down to checking if age(UserA) is negative or above 100 then say "invalid input"
( edit: other way, Dob as String input, then find find it's length is 4 or not. if no, then invalid input. )

if( userA < 0 || userA > 100 )
System.out.println( "Invalid input ");

So this make 18 input is invalid for Year.

Hope its clears now..!

Answer 2

What is the problem you are facing with this code? in terms of expected output with a sample input...!

Answer 3

Be clear about your input. Do you accepting age or year of birth? If you take age as input, then directly use it.
Like
UserA = in.nextInt();

If you take input as year, then find age by current_year - input_year.

You are mixing these two.
