Java™ How To Program (Early Objects), Tenth Edition

Section 6.10 Case Study: A Game of Chance; Introducing enum Types

• An enum type (p. 221) is introduced by the keyword enum and a type name. As with any class, braces ({ and }) delimit the body of an enum declaration. Inside the braces is a comma-separated list of enum constants, each representing a unique value. The identifiers in an enum must be unique. Variables of an enum type can be assigned only constants of that enum type.

• Constants can also be declared as private static final variables. Such constants are declared by convention with all capital letters to make them stand out in the program.
