upcasting in java
Upcasting is a type of object typecasting in which a child object is typecasted to a parent class object. By using the Upcasting, we can easily access the variables and methods of the parent class to the child class. Here, we don't access all the variables and the method. We access only some specified variables and methods of the child class. Upcasting is also known as Generalization and Widening.down casting java
public class Fruit{} // parent class
public class Apple extends Fruit{} // child class
public static void main(String args[]) {
// The following is an implicit upcast:
Fruit parent = new Apple();
// The following is a downcast. Here, it works since the variable `parent` is
// holding an instance of Apple:
Apple child = (Apple)parent;
