Class design question: Can you have an enum of class objects?

Question

Hi, thank you for reading this post!
We all know that an enum represents a set of constants, but sometimes a class has a restricted set of values as
well. My question is can we have an enum of objects.
Example:
We have a class named Coin
   A coin with a monetary value.
public class Coin implements Measurable
   private double value;
   private String name;
   public Coin(double aValue, String aName)
      value = aValue;
      name = aName;
   public double getValue()
      return value;
   public String getName()
      return name;
   public double getMeasure()
      return value;
}We all know that a coin has a set of values "Dollar" = 1.00, "Quarter" = 0.25, "Dime" = 0.10, "Nickel" = 0.05, and
"Penny" = 0.01.
Can we have an enum of Coins with Coin as a class at the same time?
If yes, how do we do this?
Thank you in advance for your help!

Answer 1

Maybe you want something like this:
public enum Coin implements Measurable {
     DOLLAR(1.00, "Dollar"),
     QUARTER(0.25, "Quarter"),
     DIME(0.10, "Dime"),
     NICKEL(0.05, "Nickel"),
     PENNY(0.01, "Penny")
     private double value;
     private String name;
     Coin(double aValue, String aName)
          value = aValue;
          name = aName;
     public double getValue()
          return value;
     public String getName()
          return name;
     public double getMeasure()
          return value;
}
