Activity-1 Write a Program in Python to Implement Polymorphism with Function and Objects. V Create Two Classes as Ferrari, BMW V fuel_type() and max_speed() are the instance methods created in both classes. V Fuel_type() : Instance method which prints Petrol for Ferrari and Diesel for BMW V max_speed()instance method which Prints Speed 350 for Ferrari and 240 for BMW V Create a function car details which can take any object as a parameter and execute its method without checking its class type. V Create Object for Class Ferrari and BMW V Show the Details of the Created Objects. %3D

Using C# language: Programming PLO-2 Measured: Design, implement, and evaluate computer solutions utilizing structured and object-oriented programming methodologies.   Design a class named Contractor. The class should keep the following information:   Contractor name Contractor number Contractor start date   Write one or more constructors and the appropriate accessor and mutator functions for the class.

Create a Class called Transaction with: instance variables: stock - your stock class type - char -> b or s (buy/sell) quantity - can be fractional price - buy/sell price when - LocalDate   constructors: constructor with parameters for stock, type and quantity. - sets the price from the stock price instance variable - sets when from LocalDate   getters and setters for each instance variable

1. A method stub is a) a short method b)a method with an abrupt end c)a  method whose header has not yet been written d) a method whose statements have not yet been written 2 An abstract class      can always be instantiated as an object      can sometimes be instantiated as an object      can often be instantiated as an object      can never be instantiated as an object  3)When a derived class defines a member method that has the same name, parameters, and return type as a base class's method, the member method is said to     overload the base class's method     overreach  the base class's method     override the base class's method     overshadow the base class's method 4. What would be the best code to print out all the elements of an array      for (int i = 0 ; i <= arry.length ; i++ ) System.out.println(arry[i]);     for (int i = 0 ; i < arry.length ; i++ ) System.out.println(arry[i]);     for (int i…
