1If you use the nextLine() method immediately following the nextInt() method, 
2nextInt() reads integer tokens; because of this, the last newline character for 
3that line of integer input is still queued in the input buffer and the next 
4nextLine() will be reading the remainder of the integer line (which is empty). 
5So we read can read the empty space to another string might work. Check below 
6code.
