Case class is a class which is defined with “case class” keywords. Case object is an object which is defined with “case object” keywords. Because of this “case” keyword, we will get some benefits to avoid boilerplate code.

We can create case class OBJECTS without USING “new” keyword. By DEFAULT, Scala compiler prefixes “val” for all constructor parameters. That’s why without using val or var, Case class’s constructor parameters will become class members, it is not possible for NORMAL classes.

Advantages of case class:

• By default, Scala Compiler adds toString, hashCode and equals methods. We can avoid writing this boilerplate code.
• By default, Scala Compiler adds companion object with apply and unapply methods that’s why we don’t need new keyword to create instances of a case class.
• By default, Scala Compiler adds copy method too.
• We can use case classes in Pattern Matching.
• By default, Case class and Case Objects are SERIALIZABLE.
