How do I write this java program using the nextInt() and hasnextInt() methods?

The instructions say to process 1 integer at a time using nextLine and looping

The instructions say to write a java program that asks for a sequence of any integers, including integers greater than 9 and less than 0, and returns an encoded output separated by spaces

For example:

Sample input: 1 1 2 3 4 4 0 -22 -22

Sample output: 1 2 2 1 3 1 4 2 0 1 -22 2
