Java creates an enum instance through reflection

Question

I want to get an instance of an enumeration type so that:

String enumString="abc"; MyClass.MyEnum enumType=Class.forName("com.MyClass.MyEnum."+enumString); 

This gives me irreversible types.

Answer 1

You are looking for MyClass.MyEnum.valueOf(enumString) . It is not necessary to fully qualify a class in a string.

Answer 2

Enum.valueOf will do this, but it is pretty legible in this type. Make sure you drop Class on Class<? extends Enum> Class<? extends Enum> . Example:

 enum Foo { BLAT, BLARG }; System.out.println(Enum.valueOf((Class<? extends Enum>)Class.forName("Foo"), "BLARG")); 

Answer 3

See Enum.valueOf (class enumType, String Name).
