b.
((S == 700) && (T = = 400))
c.
((I == S) || J = = 0))
d.
((S < 300) && ((I < 50) || (J = = 1)))
e.
((S < 300) && (!(I < 50) || (J = = 1)))
15. Determine a value of Q that will cause the condition in the if statements
below to be true:

if (Q / 3 < 9) intCount = intCount + 1
d.
if ((Q > 3) && !(Q = = 3)) dblSum = dblSum + dblAmt
16. Given the conditions S = = 0, Y = = 4, B = = 7, T = = 8, and X = = 3,
determine the action taken for each of the following:
a.
if (S > 0) JOptionPane.showMessageDialog(null,
"Computation complete.");
b.

if (X > 1) JOptionPane.showMessageDialog(null,
"Computation complete.");
c.
if ((X == 3) || (T > 2))
if (Y > 7) JOptionPane.showMessageDialog(null,
"Computation complete.");
d.
if ((X + 2) < 5)
if (B < (Y + X))
JOptionPane.showMessageDialog(null, "Computation
complete.");
