abstract class : An abstract class is a class which may or may not include abstract methods and cannot be instantiated but rather can be sub classed. The conditions for a class to be considered as legal abstract class are mentioned below: If a class includes abstract methods, then the class must be declared as abstract. The abstract method that is declared within the abstract class must be declared without braces and followed by a semicolon. Interface: Interface is a reference type in Java, which contains a collection of abstract methods. An interface needs to the follow certain conditions such as: One cannot instantiate an interface. Interfaces do not contain any constructors. All methods present in the interface are abstracts. An interface does not contain any instance field. An interface cannot be extended by a class.

Scenario You work for a small company that exports artisan chocolate. Although you measure your products in kilograms, you often get orders in both pounds and ounces. You have decided that rather than have to look up conversions all the time, you could use Python code to take inputs to make conversions between the different units of measurement. You will write three blocks of code. The first will convert kilograms to pounds and ounces. The second will convert pounds to kilograms and ounces. The third will convert ounces to kilograms and pounds. The conversions are as follows: 1 kilogram = 35.274 ounces 1 kilogram = 2.20462 pounds 1 pound = 0.453592 kilograms 1 pound = 16 ounces 1 ounce = 0.0283 kilograms 1 ounce = 0.0625 pounds For the purposes of this activity the template for a function has been provided. You have not yet covered functions in the course, but they are a way of reusing code. Like a Python script, a function can have zero or more parameters. In the code window you…
