Short for enumeration, an enumvariable typecan be found in C (ANSI, not the original K&R), C++ andC#. The idea is that instead of using anintto represent a set of values, a type with a restricted set of values is used instead. For example, if we use the colors of the rainbow, w...
As you see you can extend enum functionality in different ways. Java EnumSet EnumSetis an interesting class to work with enumeration types. It provides useful methods to create a new set of enum constants. You can do like this: Set<Color> allColors = EnumSet.allOf(Color.class); Set<Color...

An enum type is defined by the "enum" declaration statement. A simplest enum Type can be defined with 2 components: The enum type name - Specified by the declaration identifier. The enum constant list - Specified as a comma-delimited identifier list in the declaration body. ...
EnumMap: EnumMap is a specialized implementation of the Map interface that is used with enum keys. It offers high performance and type safety when working with enums as keys, thus providing efficient storage and retrieval. Benefits of HashMaps in Java Some of the benefits that HashMaps offer...
You should never ignore compiler warnings. They can break your code in weird and unexpected ways. Always fix compiler warnings. One Pass or Two? Some programming languages are written so a compiler can read the source code only once and generate the machine code.Pascalis one such language. Ma...
Enum, in C#, is a keyword that represents a value type for declaring a set of named constants. Advertisements An enum helps to define a series of related integral constants that represent special values within a module of code. An enum can be used in a switch statement, which is used as...
An enum is simply a named integer constant. Many times in coding we end up in a situation where we need to declare a variable for flag purposes; eg. add, update,delete etc. It can be done either by creating an integer variable or a string variable. Example private static void perfor...
In its most common form, an interface is a group of related methods with empty bodies. A bicycle's behavior, if specified as an interface, might appear as follows: interface Bicycle { // wheel revolutions per minute void changeCadence(int newValue); void changeGear(int newValue); void spe...
