Question

I have enum like:

public enum Enum2 
{
    ONE,TWO,THREE;
}

I can list all values like:

public static void main(String... args)
{
   for (Enum2 e : Enum2.values()) 
   {
        System.out.println(e);
   }

}

Is it possible list values if I have only string name of Enum?

String enum_name="Enum2";

E.g. if in some logic like:

if (a>b) 
{
enum_name="EnumA";
} 
else
{
enum_name="EnumB";
}

And after I receive string name of enum – I can list all values.

Answer 1

Class<?> enumClazz = Class.forName("com.mycompany.Enum2");
for (Enum<?> e : ((Class<? extends Enum<?>>)enumClazz).getEnumConstants()) {
    System.out.println(e.name()); // The variable "e" would be Enum2.ONE, etc
}

Thank you @Harry for helping me get this right.
