Can enum be Camelcase?
classes and enums are written in camel case and they are likewise constants. But classes and enums are not values (constant or otherwise); they’re types.
How is enum stored in memory?
As enum types are handled as integral types, they are stored in the stack and registers as their respective data types: a standard enum is usually implemented as an int32; this means that the compiler will handle your enum as a synonym of int32 (for the sake of simplicity, I left out several details).
Is an enum a constant Java?
A Java enum is a data type that stores a list of constants. You can create an enum object using the enum keyword. Enum constants appear as a comma-separated list within a pair of curly brackets. An enum, which is short for enumeration, is a data type that has a fixed set of possible values.
What is ordinal in enum Java?
enum ordinal() The ordinal() method returns the order of an enum instance. It represents the sequence in the enum declaration, where the initial constant is assigned an ordinal of ‘0’ . It is very much like array indexes. It is designed for use by sophisticated enum-based data structures, such as EnumSet and EnumMap .
Are there spaces in the name of an enum in Java?

Are there advantages to using tostring in Enum?
Multiple output formats may be required depending on context, parameters, etc. which toString doesn’t allow. Advantages of toString include using default string operations on the object, and in this case, using valueOf to directly translate from the human-readable version to the enum value.
