How can you tell if your class inherits from abstract classes or interfaces?
Step by step
Solved in 2 steps
- In Java, which of the following is false? An abstract class may implement an interface. A class that contains an abstract method must be declared abstract itself or a compiler message will result. A class may implement multiple interfaces. A class that extends another class may implement only one interface.Java allows implementing multiple interfaces through a single class declaration statement such as: public class Student implements Comparable, Cloneable{ //code goes here }Implement using Java Create an interface that shall have 2 methods and one string type attribute, also create an implementation class of the interface that shall define both methods (you can print YOUR favorite quote in each method body).
- Which advantages do interfaces provide? Is it not more convenient to construct objects that belong to a certain class?What is an abstract class? Choose only one option.(a) An object(b) A class with no methods.(c) A class with no concrete subclasses.(d) A class with at least one undefined message.(e) An interface.Which is true? Group of answer choices A class can implement multiple interfaces A class can inherit from multiple classes A class can implement only one interface An interface can implement multiple classes
- How do you define an interface and how do you use it in Java. what happens if anabstract class implements an interface? Is it possible to implement an interfacewithout using all the abstract methods in the implemented class? Elaborate youranswer with proper Examples andexplanations……………………………………………………..Write a java code that: a) Creates an abstract method in a superclass, then overrides it in a subclass. (Only show the methods in both classes). b) Provides a method PrintInfo () that prints your group info and can be used only in classes of the same package. c) Provides a non-overridden area() that calculates area. (choose a shape)In Java. Screenshot explains. Implement the Shape hierarchy -- create an abstract class called Shape, which will be the parent class to TwoDimensionalShape and ThreeDimensionalShape. The classes Circle, Square, and Triangle should inherit from TwoDimensionalShape, while Sphere, Cube, and Tetrahedron should inherit from ThreeDimensionalShape.Each TwoDimensionalShape should have the methods getArea() and getPerimeter(), which calculate the area and perimeter of the shape, respectively. Every ThreeDimensionalShape should have the methods getArea() and getVolume(), which respectively calculate the surface area and volume of the shape. Every class should have a member variable containing its dimensions -- for example, the Circle class should have a member variable describing its radius, while the Triangle class should have three member variables describing the length of each side. Note that the Tetrahedron cass should describe a regular tetrahedron, and as such, should only have one member…
