LIKE, SHARE & SUBSCRIBE UpCasting and DownCasting in Java. TypeCasting process is used to cast or convert our Java reference variable from one type to another type. There are two types of Typecasting present in the Java programming language : 1) UpCasting (Implicit in nature) 2) DownCasting (Explicit in nature) The main use of UpCasting is to add Run-Time Polymorphism (Dynamic Method Dispatch and Method Overriding) feature in our Java code. The main use of DownCasting is to provide an access feature to our parent class reference variable so that it can the data members of our child class. Method Overriding is used to implement Run-Time Polymorphism or Dynamic Polymorphism in our Java code. We use @Override annotation to instruct our compiler that we are overriding a Parent Class Instance Method in our Child Class.
