Override the testOverriding() method in the Triangle class. Make it print “This is theoverridden testOverriding() method”. (add it to triangle class don't make a new code based on testOverriding in SimpleGeometricObject class.) (this was the step before this one) Add a void testOverriding() method to the SimpleGeometricObject class. Make it print“This is the testOverriding() method of the SimpleGeometricObject class”
Given the Solid class, extend it with: Pyramid Cylinder RectangularPrism Sphere Make sure to create the constructor and override the volume and surfaceArea methods.

Please help to solve this codes. In Java public interface ShapesInterface{ public double getArea(); // This method returns the area of a 2 dimensional shape // or the surface are of a 3 dimensional shape. public double getVolume(); // This method returns the volume of a 3 dimensional shape // or 0 for a 2 dimensional shape. public void displayArea(); // This method displays the name of the shape and its area, // If the shape is 2 dimensional it displays the 2 dimensional area // If the shape is 3 dimensional it displays the surface area of the shape public void displayVolume(); // This method displays the name of the shape and its volume, // This method displays the volume of a 3 dimensional shape and 0 for a 2 dimensional shape. }

Object: SquareStates: sideBehaviors: computeArea(), computePerimeter() Object: RightTriangleStates: base, heightBehaviors: computeArea(), computePerimeter() - Find first the hypotenuse which is the 3rd (longest) side using the Pythagorean formula. You may use the sqrt() method defined in Math Java class KINDLY REFER TO THIS LINK BELOW:
You will create a class called Square. Length will represent the length of one side which is an integer.You should create the constructor, an instance variable, a getter method for the length of a side, a getArea method and a toString method. The area of a square = length * length.Your toString method should be written such that it would return a String of the form "Square with side length: 8” (if the side length was 8) public class Square { //create one instance variable called length //create the constructor with one parameter //create your getter method to get the length of one side with return type integer //create the getArea method with return type integer //create the toString method }
Java program: 1. Create a class named Rectangle that has instance variables height and width. Provide a constructor that initializes the instance variables based on parameter values, getter and setter methods for the instance variables, a toString method, and a method named computeSurfaceArea(), that returns the surface area of the rectangle. 2. Create a child class named RectPrism that contains an additional instance variable named depth. Provide a constructor, getter and setter methods for the new instance variable, and a method named computeVolume(), that returns the volume of the rectangular prism. Override the toString() and the computeSurfaceArea() methods. 3. Write an application called Demo, that instantiates a rectangle and a rectangular prism, and tests all the methods. Make sure you indent and comment your code based on the examples in the textbook. Don’t forget to include your name, the course number, title of the assignment, and today’s date.
Classes – Write a class to represent a AlternativeEnergyCar. Select the fields and methods that fit the modeling of an alternative energy car. Make sure to include code for the constructors, set/get methods, a toString() method.
Class RightTriangle Represents a right triangle by the length of each of its two legs Includes the default and overloaded constructor, methods to set the length of each of the two legs, amethod to get the area, a method to scale the size of the triangle, a method to invert the triangle(swap the lengths of its two legs), and a method to print its dimensions.Class TestRightTriangle Creates and initializes two triangles. Calls the various associated methods to set its size, compute its area, scale its size, invert, and print itsdimensions.You are required to implement both classes according to the requirements specified in the commentsdisplayed in the .java files. The following is an example of possible output:triangle1 dimensions: 6.0 3.5triangle1 area: 10.5triangle2 dimensions: 3.0 4.0triangle2 area: 6.0triangle1 dimensions: 18.0 10.5triangle2 dimensions: 5.5 6.5triangle1 dimensions: 4.5 2.625triangle1 dimensions after invert: 2.625 4.5A few details: Do NOT modify any of the code…
Define the Circle2DYourLastName class that contains: Two double data fields names x and y that specify the center of the circle withgetter methods. A double data field radius with getter method. A constructor that creates a circle with specified x, y, and radius. A method findTypeOfIntersection to determine and return types ofintersection as string (contained, overlap, or separate).Design a user class that prompts the user to enter the coordinates of the center andradius of two circles and displays the type of intersection. Allow the user to repeat yourprogram using a ConfirmDialog Box.
In java language Class Design – Date V0.0 & V1.0 Create a new project for this lab and create a new class inside called Date. If you created a Date class last week, you may use it as a base. What does it mean to be a Date? What data items (called “state”) do you need to keep track of? Alternatively, what does a date have? (“has a” == composition) What can a Date do? What are the actions and verbs that can be applied to a date? Come up with one or two. These become the class’s methods. Try adding 3 data items to your Date to manage the month, day and year. Should these be local variables? Class-level (or instance) variables? Now let’s build a method to set the date This function should take 3 integers as input and assign these to your instance variables declared in the previous step. public void setDate(int m, int d, int y) { And, let’s build a method to report the date This function takes no input and uses the console to output the Date in the format…
For your homework assignment, build a simple application for use by a local retail store. Your program should have the following classes: Item: Represents an item a customer might buy at the store. It should have two attributes: a String for the item description and a float for the price. This class should also override the __str__ method in a nicely formatted way. Customer: Represents a customer at the store. It should have three attributes: a String for the customer's name, a Boolean for the customer's preferred status, and a list of 5 indexes to hold Item objects. Include the following methods: make_purchase: accepts a String and a double as parameters to represent the name and price of an item this customer is purchasing. Create a new Item object with this info and append it to the internal list. If the customer is a preferred customer based on the Boolean attribute's value, take 10% off the total sale price. __str__: Override this method to print the customer's name and every…
