Is there a way to use the "values()" method from a generic enum ?

public class TCP_Message<T extends Enum<T>> {

    public T anEnum;

    public void doSomething() {
        anEnum = T.values().values[0];
    }
}

this code does not allow me to access .values().

No. You'll need to provide the class of the enum. – JB Nizet Sep 11 '17 at 17:18

If you have the `Class` object of the enum -- as you'll probably need -- you can use `getEnumConstants()`. – Louis Wasserman Sep 11 '17 at 17:22
Indeed, thanks for your answers, it works fine now. – Axel Samyn Sep 11 '17 at 18:31
