Why the scanner object not accepting the string input from stdin ?

Question

I've used scanner object for accepting 2 inputs
First int input =4 and
second string input ="ground fun"
I don't want to close the scanner object and then create a new scanner object for string input

Expected output should be
8
Playground fun

Answer 1

It's something about the buffer. Put this between line 12 and 13:
sc.nextLine()

Answer 2

nextInt() doesn't read end_of_line after number,
so nextLine() reads end_of_line
and not expected second input

in input:
4
ground fun
