Question

In Java, an Enum can do the great things that Enums do, but can also have methods (behavior and logic). What advantage does that have over using a class using an enum? Simple examples to illustrate the point would also be welcome.

Answer 1

Here’s a simple example:

enum RoundingMode {     UP {         public double round(double d) {             return Math.ceil(d);         }     },     DOWN {         public double round(double d) {             return Math.floor(d);         }     };      public abstract double round(double d); }
