Enum.valueOf(Class enumType, String name) question

I think it won’t work exactly like this unless you have access to a type variable (through either a type or method signature). The problem is the method signature of Enum.valueOf:

public static <T extends Enum<T>> T valueOf(
    Class<T> enumType,
    String name
);

There’s no way to get a T without a type variable. But you can do it like this if you’re willing to suppress some compiler warnings:

public enum King{
    ELVIS
}

@SuppressWarnings({ "unchecked", "rawtypes" })
public static void main(final String[] args){
    final Class<? extends Enum> enumType = King.class;
    final Enum<?> theOneAndOnly = Enum.valueOf(enumType, "ELVIS");
    System.out.println(theOneAndOnly.name());
}

Output:

ELVIS
