Program Plan Intro

Casting object:

  • The object casting instructs the compiler to change the type of an object to another type.
  • The objects of subclass can be assigned to the object of super class and this casting is done implicitly. This casting is called as upcasting.
  • In java, the objects of super class are not allowed to assign to subclass object implicitly. In this case, an explicit casting should be done. This casting is called as downcasting.
