Java Scanner. How to read data?

Question

Java

Reverse
I need to make a Reverse class that reads numbers from stdin and prints them to stdout in reverse order. As input, the program receives integers separated by a space.
Input example:
1 3
3

How to correctly read these characters through Scanner?

Answer 1

If no arithmetic is required, then you can just read nextLine() and then get an array of substrings by splitting the string on spaces with split(), and then output them in reverse order.
If you still need numbers, you can read them using the nextInt() method, or take the resulting substrings and convert each to an integer.
