System.out.println(x);

b) if (x = 1)

y++;

else if (x = 2)

Q2. What are the values of the following expressions? In each line, assume that

1. What are the values of the following expressions? In each line assume that [1.5 Points] double X = 2.5, Y = -1.5; int M = 18, N = 4; String S = "Hello", T = "World";

0. X + N * Y - ( X + N ) * Y

0. M / N + M % N

0. 5 * X - N / 5

0. S + T

0. S + N

0. ( 1 - ( 1 - ( 1 - ( 1 - N ))))

Q3. Write a program called CheckPassFail which read the mark from user and prints "PASS" if the mark is more than or equal to 60; or prints "FAIL" otherwise. [2 Points]
