Enumerations serve the purpose of representing a group of named constants in a programming language. #2 -Java Enums can be thought of as classes that have a fixed set of constants - Enum is named constants that we create for specific constants or error codes. - Enum is created in place of an object for constants. - Enum is pre-defined that contains all name constants. - Enums are used to create our data type like classes. - In enum, instead of returning a string format or a specific object, we can simply return a status or a value present inside an enum. e.g., enum Status{ Running, Failed, Pending, Success; } - enum is also treated as a class in Java. Objects can also be created for enum like: Status s= Status.Running; - Every enum constant represents an object of type enum. - enum type can be passed as an argument to switch statement #3 - In enum, all the name constants are defined by using numbers. - ordinal() method is used to get the index of the name constant present in the enum. - values() method is used to get all the statuses or name constants of enums. Status [][] s= Status.values(); *values() method will give an array.
