- Enumeration in Java
- What is an enum in Java?
- How to use an enum in Java?
- Methods used with enum

#1
Enum is a short term used for Enumeration.
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.
