Otherwise, marks will be deducted.Do not define extra functions except for constructors.

Create a Java program demostrating the following aspects of OOP: You must create an UML. class diagram for all the classes and interfaces in the program. Use Java interface and method overriding appropriately. Inheritance/Interface and polymorphism. Your program the base class of interface should be used as the variable/parameter type to demostrate polymorphism. Overloading using either methods or constructors. Appropriate use of this keyword. Correct use of access modifiers (public, private) in an appropriate way. Correct use of static variable and instance variable. Passing object as parameter to a method. Caling method from another method of the same class. Creating user defined classes with Encapsulation principle consideration. You are free to pick any topic/system to accomodate the above points but please keep it simple. The application does not have to be real world application meaning you can use an imaginary system for the mentioned points. Neverthless, you should be aware…
Create a base class with an abstract print( ) method that is overridden in a derived class. The overridden version of the method prints the value of an int variable defined in the derived class. At the point of definition of this variable, give it a nonzero value. In the base-class constructor, call this method. In main( ), create an object of the derived type, and then call its print( ) method. Explain the results. (JAVA)

Q1) Write the Code the following scenario. Write an abstract function named receivePay in interface with return type double and no parameters. Write another incomplete function, name Show with return type void and an argument of type int in that interface. Build a class with name Bill that implements the above interface. Bill class with name BillId , itemsquantity and itemsprice with proper datatypes with private access . Define two constructors,one default and other is parameterized to initialize the class members . Now receivePay has to beimplemented in such a way that its displays product of itemsquantity and itemsprice and Display function will display the BillId.Can we do same task with abstract class instead of interface?
