Case class is also a class, however when we compare it with normal class, it gives the following extra features or benefits:
1.By default, Case-class constructor parameters are ‘val’. We don’t need to declare parameters with ‘val’.
2.By default, Case-class constructor parameters become class fields.
3.These methods are added automatically: toString, equals, hashCode, copy. apply and unapply.
4.It automatically gets Companion object.
5.No need to use ‘new’ keyword to create instance of Case Class.
6.Easy to use in Pattern Matching.
All these features are added by Scala Compiler at compile-time. It is not possible with normal class.
