What is Enums in Salesforce Apex?

Hi Arun,

An enum is an abstract data type with values that each take on exactly one of a finite set of identifiers that you specify. Enums are typically used to define a set of possible values.

For Example.

public enum Season {WINTER, SPRING, SUMMER, FALL}

Season e = Season.WINTER;

Season CheckSeason(Season e) {
if (e == Season.SUMMER){
return e;
}
}
