Um, because you set the cell, then increment i: When it comes to the
print statement, it prints an array cell you haven't set yet, and
which has a default value of 0.

The first run of your loop is equivalent to:

arr[0] == 1;
System.out.println(arr[1] + " " + 1);

You cannot increment an increment expression: That is, "++i++" is
either equivalent to "(++i)++" or "++(i++)", neither of which make
sense.

Think of it: If i is 0 to begin with, the expression evaluates to
either "1++" or "++0", neither of which are legal.
