Use anonymous class. Example: For an abstract class AbstrClass. AbstrClass ac = new AbstrClass() { public void m1() { // code of abstract method m1. } } ;

You cannot directly create the object of an abstract class... But you can create object reference of the abstract class

Abstract classes cannot be instantiated - this is by definition and design. From the JLS, Chapter 8. Classes: A named class may be declared abstract (§8.1.1.1) and must be declared abstract if it is incompletely implemented; such a class cannot be instantiated, but can be extended by subclasses.

No. 'Abstract' means incomplete. Abstract class is also an incomplete class. Only concrete classes can be instantiated.

No, you are not creating the instance of your abstract class here. Rather you are creating an instance of an anonymous subclass of your abstract class. And then you are invoking the method on your abstract class reference pointing to subclass object.
