What do you mean by a case class in scala?

These classes in scala are the classes which are declared by using a special modifier case. The constructor parameters are exported using these case classes which hence provide a recursive decomposition mechanism through pattern matching. We treat the constructor parameters of the case classes as public values and so they can be accessed directly. The companion objects and its related methods can also be generated automatically for the case classes. All the methods in the class and the companion objects are generated based on the parameter list. It helps in automatically generating the methods from the parameter list. By default, case objects and classes are serializable.
