public enum DAYS { Monday=!, Tuesday, wednesday, Thursday, Friday, saturday, Sunday, } In the two examples given, the values of each literal has been’ unique within the enumeration. This is usually how you will want things to be, but in fact the values need notbe unique. In the foll...
Enums areused when we know all possible values at compile time, such as choices on a menu, rounding modes, command line flags, etc. It is not necessary that the set of constants in an enum type stay fixed for all time. In Java (from 1.5), enums are represented using enum data type...
This section describes 'enum' types, which are defined by 'enum' declaration statements. An 'enum' type is actually a special kind of class type.
Enum in Java provides type-safety and can be used when we know all possible values at compile time. Since enum is a keyword you can not use as variable name and since its only introduced in JDK 1.5 all your previous code which has enum as variable name will not work and needs to be...
To be precise, there is some non-trivial value that enums bring to your actual Python code. Enums become very apparent in scenarios where there is more of persistence to databases. To change the same plain old class file to an enum construct, using the libraries provided by Python programmi...
An enum is a user-defined type consisting of a set of named constants called enumerators. The colors of the rainbow would be mapped like this.: Now internally, the compiler will use an int to hold these and if no values are supplied, red will be 0, orange is 1 etc. ...

In the code, strings in static classes even look similar to enums. Developers can get the string by referring to the class and using dot notation to call the relevant string. “You have very readable code, it looks kind of enum-y, and your coding experience is about the same,” Wilson...
