- Object adapters and class adapters each provide a unique function. These concepts are also significant due to the significance that you attach to them.True or False A class can implement more than one interface.In object-oriented programming, an object is A One instance of a class B Another word for a class C A class with static method D A method that accesses a class.
- is a construct that defines objects of the same type. A class An object A method A data fieldLibrary Information System Design and Testing Library Item Class Design and TestingDesign a class that holds the Library Item Information, with item name, author, publisher. Write appropriate accessor and mutator methods. Also, write a tester program(Console and GUI Program) that creates three instances/objects of the Library Items class. Extending Library Item Class Library and Book Classes: Extend the Library Item class in (1) with a Book class with data attributes for a book’s title, author, publisher and an additional attributes as number of pages, and a Boolean data attribute indicating whether there is both hard copy as well as eBook version of the book. Demonstrate Book Class in a Tester Program (Console and GUI Program) with an object of Book class.Static variables can... ...can be accessed even without creating an object of that class. ...only be accessed by static methods. ...not be accessed using class prefix. ...not be inherited.
- The non-static class level variables and non-static methods of a class are known as a. instance members b. object behaviors c. object attributes O d. object referencesPractice with writing a program that contains three classes: Ship CruiseShip CargoShip Classes Design a Ship class with the following members: A field for the name of the ship (a string) A field for the year that the ship was built (a string) A constructor that accepts two arguments for the two fields, and appropriate accessors and mutators A toString method that returns a string with the ship’s name and the year it was built Design a CruiseShip class that extends the Ship class. The CruiseShip class should have the following members: A field for the maximum number of passengers (an int) A constructor that accepts three arguments for the three fields and appropriate accessors and mutators A toString method that overrides the toString method in the base class. The CruiseShip class’s toString method should return a string with only the ship’s name and the maximum number of passengers. Design a CargoShip class that extends the Ship class. The CargoShip class should have the…Common object behavior can be expressed using interfaces or abstract classes.What elements should you take into account when choosing between using an interface and an abstract class?
- Pick an object around you and create a class out of it - plan your class (Name, Parameters, Functionality) - your object has to have at least 4 parameters ( 2 string, 2 numbers) - your data has to be private - implement (override) the function __str__ to show the relative information for your function - create at least one extra function in your class for the object - create 4 different objects from your design class This question is based on python.True or False An interface can be used to define a set of methods that a class must implement.Pick the incorrect statement: O A class can implement more than one interface O A class can extend more than one classes O An interface can extend more than one interfaces O An interface cannot extend a class
