    In the previous sections we have seen how case classes could be used to achieve information aggregation, and also how classes could be used to achieve data abstraction or to define stateful objects.

    In the previous sections we have seen how case classes could be used to achieve information aggregation, and also how classes could be used to achieve data abstraction or to define stateful objects.

    What are the relationship between classes and case classes? How do they differ?

    Creation and Manipulation

    Remember the class definition of BankAccount:

    class BankAccount {

  private var balance = 0

  def deposit(amount: Int): Unit = {
    if (amount > 0) balance = balance + amount
  }

  def withdraw(amount: Int): Int =
    if (0 < amount && amount <= balance) {
      balance = balance - amount
      balance
    } else throw new Error("insufficient funds")
}

    And the case class definition of Note:

    case class Note(name: String, duration: String, octave: Int)

    Let’s create some instances of BankAccount and Note and manipulate them:

  77. val decided: DecidedWord
    Definition Classes
    Explicitly
  78. def defaultEquality[A]: Equality[A]
    Definition Classes
    TripleEqualsSupport

  82. val empty: EmptyWord
    Definition Classes
    MatcherWords
  83. def encoding(res0: String, res1: Boolean, res2: String): Unit

    In the above example, the same definitions of bank accounts lead to different values, whereas the same definitions of notes lead to equal values.

    In the above example, the same definitions of bank accounts lead to different values, whereas the same definitions of notes lead to equal values.

    As we have seen in the previous sections, stateful classes introduce a notion of identity that does not exist in case classes. Indeed, the value of BankAccount can change over time whereas the value of a Note is immutable.

    In Scala, by default, comparing objects will compare their identity, but in the case of case class instances, the equality is redefined to compare the values of the aggregated information.

    Pattern Matching

    We saw how pattern matching can be used to extract information from a case class instance:

    c3 match {
  case Note(name, duration, octave) => s"The duration of c3 is $duration"
}

    By default, pattern matching does not work with regular classes.

    Extensibility

    A class can extend another class, whereas a case class can not extend another case class (because it would not be possible to correctly implement their equality).

    Case Classes Encoding

    We saw the main differences between classes and case classes.

    It turns out that case classes are just a special case of classes, whose purpose is to aggregate several values into a single value.

    The Scala language provides explicit support for this use case because it is very common in practice.

    So, when we define a case class, the Scala compiler defines a class enhanced with some more methods and a companion object.

    For instance, the following case class definition:

    case class Note(name: String, duration: String, octave: Int)

    Expands to the following class definition:

    class Note(_name: String, _duration: String, _octave: Int) extends Serializable {

  // Constructor parameters are promoted to members
  val name = _name
  val duration = _duration
  val octave = _octave

  // Equality redefinition
  override def equals(other: Any): Boolean = other match {
    case that: Note =>
      (that canEqual this) &&
        name == that.name &&
        duration == that.duration &&
        octave == that.octave
    case _ => false
  }

  def canEqual(other: Any): Boolean = other.isInstanceOf[Note]

  // Java hashCode redefinition according to equality
  override def hashCode(): Int = {
    val state = Seq(name, duration, octave)
    state.map(_.hashCode()).foldLeft(0)((a, b) => 31 * a + b)
  }

  // toString redefinition to return the value of an instance instead of its memory addres
  override def toString = s"Note($name,$duration,$octave)"

  // Create a copy of a case class, with potentially modified field values
  def copy(name: String = name, duration: String = duration, octave: Int = octave): Note =
    new Note(name, duration, octave)

}

object Note {

  // Constructor that allows the omission of the `new` keyword
  def apply(name: String, duration: String, octave: Int): Note =
    new Note(name, duration, octave)

  // Extractor for pattern matching
  def unapply(note: Note): Option[(String, String, Int)] =
    if (note eq null) None
    else Some((note.name, note.duration, note.octave))

}

    We see that creating a class instance requires the keyword new, whereas this is not required for case classes.

    Also, we see that the case class constructor parameters are promoted to members, whereas this is not the case with regular classes.
