d. convoluted

5. In Java, the value of (4 > 7) is ______C______.

a. 4

b. 7

c. true

d. false

6. Assuming the variable q has been assigned the value 3, which of the following statements prints XXX? A.

a. if(q > 0) System.out.println("XXX");

b. if(q > 7); System.out.println("XXX");

c. Both of the above statements print XXX.

d. Neither of the above statements prints XXX.

7. What is the output of the following code segment? C.

t = 10;

if(t > 7)

{

System.out.print("AAA");

System.out.print("BBB");

}

a. AAA

b. BBB

c. AAABBB

d. nothing

Because the tested expression is true, both statements in the block execute.

8. What is the output of the following code segment? C.

t = 10;

if(t > 7)

System.out.print("AAA");

System.out.print("BBB");

a. AAA

b. BBB

c. AAABBB

d. nothing

The tested expression is true, so AAA prints. The second print statement is a stand-alone statement, so BBB also prints.

9. What is the output of the following code segment? D.

t = 7;

if(t > 7)

System.out.print("AAA");

System.out.print("BBB");

a. AAA

b. BBB

c. AAABBB

d. nothing

The tested expression is false, so AAA does not print. The statement that prints BBB is not
