How can I implement sequential input?

Question

I have a code
int a = new Scanner(System.in).nextInt();
int b = new Scanner(System.in).nextInt();
but the compiler does not see the second input(

Answer 1

Miu-miu HASKEER if by sequential you mean an infinite amount of lines as input, do it like this:

Answer 2

Create a single scanner, multiple that use the same stream at the same time will cause problems.

Scanner sc = new Scanner(System.in);

int a = sc.nextInt();
int b = sc.nextInt();

Then input it like so on code playground:
10
20

a will receive the value '10'.
b will receive the value "20'.

Answer 3

strange that I did not work, because it is working now
