Traverse the collection: Using enumeration makes it easy to iterate through all elements in a collection, such as an array, list, set, etc.
State machine: In state machine design, enumerations can be used to represent different states, simplifying the process of state switching and handling.
Configuration options: Enumerations can be used to represent a group of configuration options, enhancing code readability and maintainability.
Singleton pattern: When implementing the singleton pattern, you can use enums to ensure thread safety and achieve lazy loading.
Constant definition: enums can be used to define a set of constants, making the code more readable.
Error code: When handling exceptions and errors, it is helpful to use enums to represent different error codes for easier management and identification.
Status code: In network communication or interface calls, different status codes can be represented using enumerations for easier understanding and handling of error situations.
Finite state machine: Enumeration can be used to implement finite state machines, simplifying state transitions and processing logic.
