2 <clause number="8.11" title="Enums" informative="true">
3 <paragraph>An enum type declaration defines a type name for a related group of symbolic constants. Enums are used for "multiple choice" scenarios, in which a runtime decision is made from a fixed number of choices that are known at compile-time. </paragraph>
4 <paragraph>The example <code_example><![CDATA[
13 public void Fill(Color color) {
29 ]]></code_example>shows a Color enum and a method that uses this enum. The signature of the Fill method makes it clear that the shape can be filled with one of the given colors. </paragraph>
30 <paragraph>The use of enums is superior to the use of integer constants-as is common in languages without enums-because the use of enums makes the code more readable and self-documenting. The self-documenting nature of the code also makes it possible for the development tool to assist with code writing and other "designer" activities. For example, the use of Color rather than <keyword>int</keyword> for a parameter type enables smart code editors to suggest Color values. </paragraph>
