What does the program print?

JAVA

public class Main {
    public static void main(String[] args) {
        System.out.print(1);
        System.out.print(2);
        System.out.println(3);
    }
}

123

Expecting 1 2 3: print adds neither a space nor a line break, so the values stay glued into 123 until println ends the line.
Expecting 6: nothing adds the numbers up; print(1) and print(2) each print their own value, and println(3) prints 3.

What does System.out.println() with no argument print?
How would you print 1 2 3 on one line, with spaces between the numbers?
