This document contains 15 multiple choice questions about loops, conditionals, and other control structures in Java. Key points covered include: 1) A for loop automatically increments the counter after each iteration. 2) A do-while loop will always execute the code at least once, even if the conditional statement is never true, unlike a regular while loop. 3) Loops are useful because they allow code to be repeated a variable number of times until a certain condition is met.

1. Quiz5
1.In a for loop,
the counter is
automatically
incremented
after each
loop
iteration.
True or
False?

(1) Points
True
False (*)
Correct
2. A counter used in a for loop cannot be initialized within the
For loop statement. True or False?
Mark for Review
(1) Points
True
False (*)
Incorrect. Refer to Section 5
Lesson 2.
3. What is one significant difference between a while loop
and a do-while loop?
Mark for Review
(1) Points
A DO-WHILE loop does not exist in Java and a
WHILE loop does.
A DO-WHILE loop will always execute the code at
least once, even if the conditional statement for the
WHILE is never true. A WHILE loop is only executed
if the conditional statement is true. (*)
A DO-WHILE loop includes an int that serves as a
counter and a WHILE loop does not.
There is no difference between a DO-WHILE loop and
a WHILE loop.
Correct
4. Why are loops useful?
Mark for Review
(1) Points
They save programmers from having to rewrite code.
They allow for repeating code a variable number of
times.
They allow for repeating code until a certain argument
is met.
All of the above. (*)
Incorrect. Refer to Section 5
Lesson 2.
5. Which of the following best describes a while loop?
Mark for Review
(1) Points
A loop that contains a segment of code that is executed
before the conditional statement is tested.
A loop that executes the code at least one time even if
the conditional statement is false.

2. A loop that is executed repeatedly until the conditional
statement is false. (*)
A loop that contains a counter in parenthesis with the
conditional statement.
Correct
6.How many
times will
the
following
loop be
executed?
What is the
value of x
after the
loop has
finished?
What is the
value of
count after
the loop
has
finished?
int count =
17;
int x = 1;
while(count
> x){
x*=3;
count-=3;
}

5; 27; 8
3; 9; 11
5; 30; 5
3; 27; 8 (*)
4; 8; 27
Incorrect. Refer to Section 5 Lesson

7. What is the function of the word "break" in Java?
Mark for Review
(1) Points
It does not exist in Java.
It exits the current loop or case statement. (*)
It continues onto the next line of code.
It stops the program from running.
Incorrect. Refer to Section 5 Lesson
2.
8. How would you use the ternary operator to rewrite this if
statement?
if (skillLevel > 5)
numberOfEnemies = 10;
else
numberOfEnemies = 5;
Mark for Review
(1) Points

3. numberOfEnemies = ( skillLevel >= 5) ? 5 : 10;
numberOfEnemies = ( skillLevel > 5) ? 5 : 10;
numberOfEnemies = ( skillLevel < 5) ? 10 : 5;
numberOfEnemies = ( skillLevel >= 5) ? 10 : 5;
numberOfEnemies = ( skillLevel > 5) ? 10 : 5; (*)
Incorrect. Refer to Section 5 Lesson
1.
9. In an if-else construct, the condition to be evaluated must be
contained within parentheses. True or False?
Mark for Review
(1) Points
True (*)
False
Incorrect. Refer to Section 5 Lesson
1.
10. The three logic operators in Java are:
Mark for Review
(1) Points
&&, !=, =
!=, =, ==
&, |, =
&&, ||, ! (*)
Correct
11.switch
statements
work on
all input
types
including,
but not
limited to,
int, char,
and
String.
True or
false?
Mark for Review
(1) Points
True
False (*)
Correct
12. Which of the following could be a reason to use a switch
statement in a Java program?
Mark for Review
(1) Points
Because it terminates the current loop.
Because it allows the user to enter an input in the console
screen and prints out a message that the user input was
successfully read in.
Because it allows the code to be run through until a
certain conditional statement is true.
Because it allows the program to run certain segments of
code and neglect to run others based on the input given.
(*)
Incorrect. Refer to Section 5 Lesson
1.

4. 13. This keyword is used to instruct specific code when the input
for a switch statement that does not match any of the cases.
Mark for Review
(1) Points
switch
case
break
default (*)
None of the above
Incorrect. Refer to Section 5 Lesson
1.
14. What is the difference between the symbols = and == ?
Mark for Review
(1) Points
The symbol = is used in if statements and == is used in
loops.
The symbol == is used to assign values to variables and
the = is used in declarations.
The = is use to assign values to variables and the ==
compares values. (*)
There is no difference.
Incorrect. Refer to Section 5 Lesson
1.
15. Which of the following correctly matches the switch
statement keyword to its function?
Mark for Review
(1) Points
(Choose all correct answers)
switch: identifies what element will be compared to the
element of the case statements to find a possible match
(*)
switch: tells the compiler the value to compare the input
against
case: signals what code is executed if the user input
matches the specified element (*)
default: signals what code to execute if the input does not
match any of the cases (*)
if: records the user's input and sends it to the case
statements to find a possible match
Incorrect. Refer to Section 5 Lesson
