What are case classes, why do we have them, and how do we use them? These are a few questions you may want an answer to. So, in simpler words, a case class can omit the amount of code we may have to write to achieve this:
class Country(val name: String, val capital: String) {
override def toString: String = s"Country($name,$capital)"
override def equals(obj: scala.Any): Boolean = ???
override def hashCode(): Int = ???
}
Instead of declaring Country as we do in the preceding code, we would prefer to do the following:
case class Country(name: String, capital: String)
And our case class Country definition takes care of the rest. We have accessor methods for our name and capital members. We have our toString and equals methods ...
