  System.out.print ("   " + k);

Why is the answer k%3?

Do you know what is the % operator?

Why is the answer x != 5 && y <= 2

Do you know De Morgan's laws? (hint: search on Wikipedia)
This is inherent to boolean algebra.

Why is the answer x = y; else x = z

If y is lower than z, what is the smaller? And otherwise?
