1. Use the ? construction to assign to the variable sign the value +1 is i is positive and -1 if i is non-positive.

  sign = (i > 0)? 1 : -1

2. What is printed by the following code fragment? Trace your results, do not just guess.

for (i = 0, j = 2; i < 4 && j > 0; i++, j--)  
  System.out.println(i + " " + j); 

Tracing: i = 0 then 1 then 2 
         j = 2 then 1 then 0
         
What will be printed:

0 2
1 1
