![]() An enum class can include methods and fields. ![]() It was introduced with the release of Java 5. Java program to demonstrate getDeclaringClass () method. Syntax : public final Class getDeclaringClass () Parameters : NA Returns : the Class object corresponding to this enum constants enum type.`enum` keyword: in order to create an enum list, we start with the keyword `enum`.Īfter the keyword `enum` we set the name of the enum(in the example above it was `Color`) and after that we declare the list of constant values (objects) in the body of the enum. In Java, enum types are considered to be a special type of class. Any Two enum constants e1 and e2 are of the same enum type if this method returns the same Class object for both. Here the name of the enum is `Color` and its constant values (objects) are `BLACK`, `RED` and `BLUE` and all of these values are basically objects of type Color. How to create enums in Java? (Enum syntax) Static means in order to access the members of an enum class (its values (AKA objects)), we need to use the name of that class.Ĭonstant means: the objects (values) in an enum will stay with that enum for as long as the program is alive. The Java enum constants are static and final. We say an enum is a special class this means we can add attributes and methods (basically members that we can use inside a class) inside the body of an enum as well. Java Enums can be thought of as classes which have a fixed set of constants (a variable that does not change). Learn how to use enum in Java with code examples of all advanced features including constructors, methods, and switch expressions (Java 12). The `enum` is a special class that represents a list of static constant objects of its type. This value will be read by the barista who prepares the customer. We are writing a program that prints out the size of coffee a customer has ordered to the console. Now that we have declared an enum, we can refer to its values in our code. In this tutorial we will learn what the enums are and how to use them in Java. In this example, we have declared an enum called Sizes which has three possible values.
