Records with Local Enumerated Types (Java 17)

 Records with Local Enumerated Types (Java 17)

Starting from Java 17, records can include local enumerated types, providing more flexibility and convenience when working with records. This allows you to define an enumerated type directly within a record's body. Here's an example:

record Person(String name, int age, Gender gender) {

    enum Gender {

        MALE, FEMALE, OTHER

    }

}

In this example, the Person record includes a local enumerated type Gender within its body. The Gender enum defines three constants: MALE, FEMALE, and OTHER. The Person record can then use the Gender enum as the type for the gender property.

Using local enumerated types within records helps encapsulate and organize related types within the scope of the record itself. It provides a convenient way to define and use enums that are specific to the record's purpose.

Exploring records with local enumerated types can improve the organization and readability of your code, especially when working with records that require specialized enumerated types.
