Is_it_possible_to_access_copy_function_of_data_class_in_Java_with_optional_parameters_.kt

Is it possible to access copy function of data class in Java with optional parameters?  e.g I want to change a3 in Java. What is the best way to do it considering my class A is immutable.
Should I write setter method which internally should do a copy by updating the required value or is there any other option?

Since java doesn't support named/optional parameters, you'll have to make a custom copy function in kotlin for java.

```fun copyWithA3(a3: Int) = copy(a3 = a3)```
