What are the advantages of using Java enums?

The advantages of Java enumeration classes are as follows:

1. The code is easily readable: Each member in the enumeration class has a meaningful purpose, allowing the enumeration class to clearly represent the meaning of a certain state or option, making the code more readable and maintainable.
2. Type safety: each enum member is an instance of that enum class, so there is no risk of other types of instances being mistakenly passed to the enum class or to other methods.
3. Value constraints: members in the enumeration class are limited, allowing the input values to be restricted to only those in the enumeration class, preventing the entry of invalid or incorrect parameters.
4. Additional properties and methods can be added: In addition to having fixed members, an enum class can also add other properties and methods within its enum members, increasing flexibility and scalability.
5. You can iterate through Enumerations by implementing the Iterable interface, allowing you to use an enhanced for loop to traverse the enumeration members.
6. Thread safety: Instances of the enum class are unique, eliminating the possibility of race conditions in concurrent multi-threaded access.
