Expert Solution & Answer
Chapter 5, Problem 4RE
a.
Program Description Answer
A method does not have exactly one “return” statement.
Hence, the correct option is “False”.
b.
Program Description Answer
A method need not contain one “return” statement.
Hence, the correct option is “False”.
c.
Program Description Answer
A method should contain at most one “return” value.
Hence, the correct option is “True”.
d.
Program Description Answer
A method with “return” value “void” can contain a “return” statement.
Hence, the correct option is “False”.
e.
Program Description Answer
The method will exit immediately, when a “return” statement is executed.
Hence, the correct option is “True”.
f.
Program Description Answer
A method with return value “void” does not print a result.
Hence, the correct option is “False”.
g.
Program Description Answer
A method without parameter variables does not return the same value.
Hence, the correct option is “False”.

A return statement is the same as a print statement. Anything that a method returns will automatically get printed.
True
False
a) Write a boolean method called sumDivisibleByFive that returns true if the sum of the digits of its integer
parameter is divisible by 5 and false otherwise. For example, if the parameter passed to the method is 73
then the sum of its digits is 10 (7+3) The method should return true since 10 is divisible by 5.
b) Write a main method that calls the method sumDivisibleByFive for the values between 10 and 100
inclusive 10 per line. This should output the following numbers:
14 19 23 28 32 3741 46 50 55
64 69 73 78 82 87 91 96
True or False: When passing multiple arguments to a method, the order in which the arguments are passed is not important.

- a. Plan the logic for an insurance company program to determine policy premiums. The program continuously prompts the user for an insurance policy number. When the user enters an appropriate sentinel value, end the program. Call a method that prompts each user for the type of policy needed—health or auto. While the user’s response does not indicate health or auto, continue to prompt the user. When the value is valid, return it from the method. Pass the user’s response to a new method where the premium is set and returned—$550 for a health policy or $225 for an auto policy. Display the results for each policy. b.Modify Exercise 9a so that the premium-setting method calls one of two additional methods—one that determines the health premium or one that determines the auto premium.
