Why can't I use nextLine() or next() after nextInt()?

Question

Is it a bug? Then why isn't it fixed? If its not, then why oracle hasn't changed it. It would've helped many.
Any workarounds?
Thanks :D

Answer 1

Hi
nextInt() has no carriage return attached to so you need to clear the Scanner before you can use it again an example would be

Scanner input = new Scanner (System.in);

int a = input.nextInt();
input.next ();
String a = input.nextLine();

hope this helps

if you have a problem with a piece of code please post it and I will take a look for you and try to explain

Answer 2

nextInt() will grab the next integer value from the input stream. nextLine() will try to grab a whole line at a time all the way to the end of line characters. If you have no other characters after the integer before your new line and carriage return then it makes sense that the nextLine wouldn't work as expected.

Answer 3

Thank you for the help. I was wondering why hasn't Oracle added a carriage return to nextInt() as A^dr3w stated? Is it hard? Or is it just impossible? Sorry, if the question is dumb but I really want to know why haven't they made it easier for the coders.
