isEmpty of type boolean, indicating whether a class roster is empty or not.
numberOfCredits of type int, containing the number of credits for a class.
The expression that evaluates to true if the class roster is not empty is :
(isEmpty == false) && (numberOfCredits == 3 || numberOfCredits == 1)
Step-by-step explanation:
Two variables, isEmpty of type boolean, indicating whether a class roster is empty or not, and numberOfCredits of type int, containing the number of credits for a class.
An expression that evaluates to true if the class roster is not empty and the class is more than two credits is
(isEmpty == false) && (numberOfCredits == 3 || numberOfCredits == 1)
If isEmpty is false, then the number of credits can be either three or one.
The statement shows the expression.
