Question

How would you refactor this code using apply?

Problem

Consider:

class Message(message: String, signature: String) {

  val body = MessageBody()

  

  init {

    body.text = message + "\n" + signature

  }

}

Do you see any refactoring that could be done?

Answer 1

You can write:

class Message(message: String, signature: String) {

  val body = MessageBody().apply {

    text = message + "\n" + signature

  }

}
