What is enumeration in Java?

Question

I could not understand enumeration in Java. Please explain enumeration with an example.

Answer 1

Enumeration is also called as enum. The enumeration in java is a kind of class that contains a set of constants also called enumerators.

We can create enum by adding enum keyword before the class name. Declare the constant variables inside the enum and all these variables in enum should be in capital letters.

Example:

enum gameLevel {

  BEGINNER,

  INTERMEDIATE,

  ADVANCE

}

Use the dot operator to access enum variables:

gameLevel myVar = gameLevel.INTERMEDIATE;
