Last Updated : 06 May, 2024 Comments Improve Suggest changes Like Article Like Report Using the copy function that case classes offer, you may clone an instance of a case class in Scala and modify a single field. You may create a new instance of a case class with updated fields while maintaining the integrity of the other fields by using the copy method that case classes automatically produce. Utilizing the Copy MethodScala case classes have a useful method called copy that generates a new instance of the case class with a few updated fields. Below is the Scala program to implement the above approach: Scala // Define a case class case class Person(name: String, age: Int) // Create an instance of the case class val person1 = Person("Alice", 30) // Clone the instance and change just one field val person2 = person1.copy(age = 35) // Output println("Original Person: " + person1) println("Modified Person: " + person2) In this example, the person1 instance's copy method is used to create a new instance, person2, with the name field left unaltered and the age field set to 35.
