Question

How are constants assigned to variables declared using an enumerated type?

a) variableName = enum typeName.VALUE_X;
b) variableName = VALUE_X;
c) enum typeName.VALUE_X = variableName;
d) enum typeName = variableName.VALUE_X;

Answer 1

In programming, an enumerated type's constant is assigned to a variable using the syntax 'variableName = enum typeName.VALUE_X;'. This assigns the specified constant from the enumerated type to the variable.

Step-by-step explanation:

When working with enumerated types in many programming languages, constants are assigned to variables using a specific syntax. The correct syntax for assigning a value from an enumerated type to a variable is generally the one mentioned in option (a), which is:

variableName = enum typeName.VALUE_X;

This statement assigns the constant VALUE_X defined within the enumerated type typeName to the variable variableName. An example could be an enum named Color with a constant RED. The assignment would look like:

Color myColor = Color.RED;

This line of code correctly sets the variable myColor to the constant RED from the enumerated type Color.
