Note:  "\t" is different than 8 spaces, because it moves the output cursor forward up to 8 spaces, depending on where the cursor is at right now.  For example, in
System.out.println("HI\tTHERE!");
the "\t" will move the cursor forward 6 spaces, to get to the next multiple of 8. Like this:
HI      THERE!
But in 
System.out.println("HELLO\tTHERE!");
You only get 3 spaces after HELLO (because the cursor is 5 letters toward column 8).
HELLO   THERE!
In both cases, the "T" in  "THERE!" is placed in column 8.
