Question

Given the following code sample, which of the following statements assigns the flavor enumerated type value to the integer variable n?

a) int n = Flavor.CHOCOLATE.getValue();
b) int n = Flavor.VANILLA.ordinal();
c) int n = Flavor.STRAWBERRY.index();
d) int n = Flavor.CARAMEL.toInt();

Answer 1

The correct way to assign an enumerated type value to an integer variable in Java is using the .ordinal() method. Therefore, the statement 'int n = Flavor.VANILLA.ordinal();' correctly assigns the ordinal value of VANILLA to the integer n.

Step-by-step explanation:

The student's question pertains to enumerations in programming, where the objective is to assign an enumerated type value to an integer variable. In Java, the .ordinal() method can be used to get the position of an enum constant, which is zero-based. Thus, the correct statement that assigns the flavor enumerated type value to the integer variable n would be:

b) int n = Flavor.VANILLA.ordinal();

This line of code will assign the ordinal value of VANILLA within the Flavor enum to the integer variable n. The .ordinal() method returns the index of the enum constant, which is an int value. The other options provided do not correspond with standard methods available in Java enum types and would result in a compilation error or are inaccurate unless those methods are explicitly defined in the Flavor enum.
