Answer 2

Answer:

If a field is declared as var, Scala creates both getter and setter methods for that field. If the field is a val, Scala only spawns a getter method for it.

Explanation:

Here's the abridged version here:

• If a field is declared as var, Scala generates both getter and setter methods for that field.
• If the field is a val, Scala only generates a getter method for it.
• If a field does not have a var or val modifier, Scala becomes conservative, and does not generate a getter or setter method for the field.
• Additionally, the var and val fields can be modified with the private keyword, which prevents getters and setters from being generated.
