How would you override default getter for Kotlin data class?

Given the following Kotlin class:

data class Test(val value: Int)

How would I override the Int getter so that it returns 0 if the value negative?

1. Have your business logic that creates the data class alter the value to be 0 or greater before calling the constructor with the bad value. This is probably the best approach for most cases.
2. Don’t use a data class. Use a regular class.

   class Test(value: Int) {
      val value: Int = value
       get() = if (field < 0) 0 else field
   
       override fun equals(other: Any?): Boolean {
        if (this === other) return true
        if (other !is Test) return false
        return true
      }
   
      override fun hashCode(): Int {
        return javaClass.hashCode()
      }
   }

3. Create an additional safe property on the object that does what you want instead of having a private value that’s effectively overriden.

   data class Test(val value: Int) {
     val safeValue: Int
       get() = if (value < 0) 0 else value
   }
