This is really useful because it provides more context and meaning to your code. If you want, you can also provide one or more constructors to your Enum as it also supports constructor overloading like normal Java classes. This is very different from the enum you have seen in C or C++...
Enums are useful when we need to define a set of named values that have a specific meaning in our application. Here is an example of a Java enum: public enum OrderStatus { PENDING, IN_PROGRESS, COMPLETED, CANCELED } In this example, the OrderStatus enum defines four constants. These con...
2.3. Iterate UsingforEach() TheforEach()method was added to theIterableinterface in Java 8. So all the java collection classes have implementations of aforEach()method. In order to use these with anEnum, we first need to convert theEnumto a suitable collection. We can useArrays.asList()...
DataEnum is in Beta status, meaning it is used in production in Spotify Android applications, but we may keep making changes relatively quickly. It is currently built for Java 7 (because Android doesn't support Java 8 well yet), hence the duplication of some concepts defined injava.util.fun...
Added Functionality:Java enum has powerful features, unlike traditional languages where enumerations are just named integers. Enums in Java are objects, meaning they can have constructors and methods and even implement interfaces, which opens a whole new world of possibilities, making Java Enum versa...
, meaning it may or may not be legal and you have to explicitly check it. (Optionals are essentially a syntactic Maybe Monad, and way off topic.) You can even define an enumeration in terms of itself, which is just all kinds of weird. From the documentation: indirect enum Arithmetic...
Determine whether the given set is "full" (meaning it contains all possible values). Parameters: authentications - the set Returns: true if the set is full, false otherwise in public boolean in(Authentication value1, Authentication value2) Determine whether this...
, 0. C# enums are type safe meaning. You cannot implicitly convert from the underlying type to the actual enum. Also, you cannot assign a value of one enum to another enum, even though the underlying types of both the enums are same. An explicit cast is always required....
public class DeploymentLogEnumDeploymentType extends java.lang.Object implements java.io.SerializableThis class holds the value of the DeploymentLog.deploymentType property. That property is an "enumerated" type, meaning that it has a predefined set of allowed values. Each of those values has an ...
Returns the name of this enum constant, as contained in the declaration. This method may be overridden, though it typically isn't necessary or desirable. An enum class should override this method when a more "programmer-friendly" string form exists. ...
