I have an enumeration Class and I want to use the values in it in order to populate a ComboBox.

The enum class :

public enum Drink {
    Water, Milk, Coffee, Thea, wine
}

The controller class :

@FXML
private JFXComboBox DrinkComboBox;

private void SetComboBox(JFXComboBox DrinkComboBox)
{
    // fill this.DrinkComboBox with value of enum Drink
}

An enum has a values() method that returns an array containing all values of the enum.

So all you need is

@FXML
private JFXComboBox<Drink> drinkComboBox;

private void SetComboBox() {
   this.drinkComboBox.getItems().setAll(Drink.values());
}

Access enum from another class, There are at least two possible solutions here: Place the Suit enumeration in its own file. Access Suit with its fully qualified name in other classes. That is use  Use enumeration classes instead of enum types. 10/08/2018; 2 minutes to read +3; In this article. Enumerations (or enum types for short) are a thin language wrapper around an integral type. You might want to limit their use to when you are storing one value from a closed set of values.

If you want to iterate over the enums:

for (Drink drink : Drink.values()) {
   //do things with drink
}

S.4.5a, C++11 defines a new concept, the enum class (also called a scoped have to use a scope qualifier to access the enumerator (e.g. Color::red). However, with enum classes, the strong scoping rules mean that all enumerators are considered part of the enumeration, so you have to use a scope qualifier to access the enumerator (e.g. Color::red). This helps keep name pollution and the potential for name conflicts down.

Oracle has some great tutorials on enums. Enum Tutorial. The the .value() method should give you what you want.

Enum Types (The Java™ Tutorials > Learning the Java Language , The enum class body can include methods and other fields. The compiler Note: The constructor for an enum type must be package-private or private access. My problem is, that I have a method which takes as an input parameter a class (Class c) and within the method I check whether or not it is an enum (c.isEnum()). If it is an enum, I would need to somehow get the enum values, the problem is that I don't know quite how to do this, I'm not even totally sure it is possible.

If you want to search and return only the names of directories or files, use the enumeration methods of the Directory class.

Using Enumeration classes instead of enum types, NET Microservices Architecture for Containerized .NET Applications | Lear how you can use enumeration classes, instead of enums, as a way  The enum class body can include methods and other fields. The compiler automatically adds some special methods when it creates an enum. For example, they have a static values method that returns an array containing all of the values of the enum in the order they are declared. This method is commonly used in combination with the for-each construct to iterate over the values of an enum type.

enum class, When an unscoped enumeration is a class member, its enumerators may be accessed using class member access operators . and -> : struct X  Creating the enumeration class. To move away from an enumeration to an enumeration class, I’ll first use the Enumeration layer supertype from our “default architecture” we use at Headspring, from Tarantino: It’s a large class, but it gives us some nice functionality out of the box, such as equality operations and such.
