Can an enum be an array?

Use the element() method of vector to get the enumeration of the vector element. Using the list(Enumeration e) method of the Collections to get the ArrayList.

Enums are lists of constants. When you need a predefined list of values which do represent some kind of numeric or textual data , you should use an enum. You should always use enums when a variable (especially a method parameter) can only take one out of a small set of possible values.

The idea is to use the Enum. GetValues() method to get an array of the enum constants’ values. To get an IEnumerable<T> of all the values in the enum, call Cast<T>() on the array. To get a list, call ToList() after casting .

To get all values of an enum, we can use the Enum. GetValues static method . The Enum. GetValues method returns an array of all enum values.

You can create a list that holds enum instances just like you would create a list that holds any other kind of objects: ? List<ExampleEnum> list = new ArrayList<ExampleEnum>(); list.

A Java Enum is a special Java type used to define collections of constants . More precisely, a Java enum type is a special kind of Java class. An enum can contain constants, methods etc. Java enums were added in Java 5.
