# What is enum datatype in java

Enum keyword is used to represent a fixed number of related values. Since enum constants are implicitly static and final,there values can't be changed once they are created.

```
public enum Day { SUNDAY, MONDAY, TUESDAY, WEDNESDAY,THURSDAY, FRIDAY, SATURDAY }// Uses public void weekDay() { switch (day) { case MONDAY: System.out.println("Mondays are bad."); break; }}
```
