What are the characteristics of the hashCode implementation in a data class in Kotlin?

In Kotlin, a data class automatically generates the methods equals(), hashCode(), and toString(), based on all properties declared in the primary constructor. The feature of hashCode() implementation in a data class is that it combines the hash codes of all these properties using a standard algorithm to ensure correct comparison and usage of objects in collections such as HashMap or HashSet.

For example, if a data class contains several properties, hashCode() will be computed as a combination of their hashes, ensuring that two objects with the same property values have the same hashCode.
