int c = 3;

Which of the following expressions evaluates to false ? -Correct Answer-D. a < b != c < b



Consider the following code segment.

boolean a = true;

boolean b = false;

System.out.print((a == !b) != false);

What is printed as a result of executing this code segment? -Correct Answer-B. true



Consider the following expression.

(3 + 4 == 5) != (3 + 4 >= 5)

What value, if any, does the expression evaluate to? -Correct Answer-A. true



Consider the following code segment.

int quant = 20;

int unitPrice = 4;

int ship = 8;

int total;

if (quant > 10)

{

unitPrice = 3;

}

if (quant > 20)

, {

ship = 0;

}

total = quant * unitPrice + ship;

What is the value of total after this code segment has been executed? -Correct Answer-C. 68



Consider the following code segment.
