Upcasting and downcasting in Java are the two forms of typecasting.Parent p1 = new Child() Child c1 = (Child)p1 Methods and variables of both the Parent and Child classes can be accessed through downcasting. Methods and variables of the Parent class can be accessed. ![]() Implicit downcasting is not allowed in Java. Implicit, as well as explicit upcasting, is allowed. Upcasting refers to typecasting a child object to a parent object.ĭowncasting provides casting a parent object to a child object. Look at the code below which show how this implicit typecasting is possible. And a child object can definitely exhibit the properties of its parent, which is why a child object can be implicitly typecasted as a parent object. Each of these child objects inherits the properties from their parent, i.e. Sport is a parent object whereas Cricket and Football are the child object. Now, let's see how we are going to understand it in terms of upcasting. Sport, in common, is a parent object and each of its different forms is its child object and they have an IS-A relationship.

Upcasting and downcasting in Java are the two forms of typecasting where conversion of data type takes place. Downcasting (or narrowing) is typecasting from a superclass to a subclass so that we can access the methods of the subclass, i.e., the child class.
