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;
 }
}
