Calendar cal=Calendar.getInstance() We know that Calendar is an abstract class so it can't be instantiated. So how we can say that cal is an instance of Calendar???

Beginner Question I suppose. Thanks in advace.

Hi , yes Calendar is an abstract class and it is not possible to create object directly by invoking the constructors in Calendar class.

Calendar cal=Calendar.getInstance()

In this cal is not a object to Calendar class directly , it is a object to java.util.GregorianCalendar class. Hear GregorianCalendar is sub class to Calendar and it is not a abstract. In this above code we are handling the GregorianCalendar class object by using it's super class Calendar class reference variable.
