(col.valueOf ('RED')) Įxample of value(), ordinal() and ValueOf() The below example shows enum methods as follows:

The value of the method returns the enum constant, which was specified by using the existing string value. Order is important in enum methods while using the ordinal method, each enum index is found in the array of indexes. The values method returns all the values present inside the enum. The below example shows enum methods as follows. If the enum class contains abstract methods, then every instance of the enum class implements the same. The enum will contain abstract and concrete methods. ('Tue is third day.') Įnum_class ec = new enum_class(Day.valueOf (str)) In the below example, we are giving day as an enum data type as follows. The below example shows a switch statement with an enum data type as follows. In the following example, an enum is employed with a switch statement to designate the level. The switch statement utilizes the enum data type to examine values. We can also pass the enum data type by using a switch statement. We are creating the class name as enum_class as follows. In the below example, we are defining the enum datatype outside of the class as follows. We are creating the class name as enum_class as follows: In the below example, we are defining the enum datatype inside the class as follows: Like we give the constructor and also add the instance variables. In Java, an enum is defined as a class type, so we do not need to instantiate the enum using new it will contain the same capabilities as other classes. In Java, we define enums inside and outside of a class. It is not necessary to keep the enum type constants fixed all of the time.

In Java, we use an enum when we know that all possible values will be available at the time of compilation. The enumeration in Java represents a group by incorporating named constants into the programming language. The enum-type fields are always in capital letters. Because it will be constants, we can say that the enum example compass directions. The variable we have defined is equal to the values we have defined. In Java, an enum is a special data type that enables variables to set predefined constants. The above example illustrates clearly where the enum is the keyword followed by the name of user-defined datatypes and the value of user-defined datatypes. It works so that any enumeration of Java within a class is provided using a keyword with an enum followed by the type of datatype for a user and then giving values of user-defined datatypes. To illustrate the syntax more precisely enum days Syntax: enum (name of user defined datatype) Java Enumeration in Java appears almost like enumerations in other languages besides the fact that the concept of classes and object orientation comes into the picture in Java.

The Enumeration in Java came into existence in full fledge after releasing versions of JDK 5. In Java, enumerations act as a final variable once declared, they help explain the concept being introduced within the program’s set of statements and control flow. Java Enumeration signifies a set of constants contained within a class that denotes and specifies the functionality of the declarations made before the program’s execution begins. It is a special class representing the constant group, like the final variable.

To define the enum in Java, we use the enum keyword.

We use an enum to create our classes and an enum keyword to create our enum type.
