In line no 15-
A a=new B();
Here, we are creating an object of class B, with reference of class A i.e, creating subclass object with superclass reference. In such a case, the subclass method gets executed, and superclass variable is executed.
Hence, output will be Value-B 10.
Moreover, there is a small but major error. printValue() method is a non-static method and should be invoked by the object of the class, somewhat like a.printValue();
