What is the method to incorporate a space between the digits when using System.out.print?

edit

One method to incorporate a space between the digits when using System.out.print is to use the concatenation operator "+" to add a space character " " between the digits. For example:

System.out.print(digit1 + " " + digit2);

This would print the value of digit1 followed by a space character, followed by the value of digit2.
