Computer Science Develop an inheritance hierarchy based upon a Polygon class that has methods area () and perimeter (). Implement classes Triangle and Quadrilateral that extend this base class, with the obvious meanings for the area () and perimeter () methods. Also implement classes, Isosceles_Triangle, Equilateral_Triangle, Rectangle, and Square, that have the appropriate inheritance relationships. are similar (have the same number of the sides).

Implement the following hierarchy shown in Figure 1, using Java Inheritance. The class Student is the parent class. Note that all the variables are private and hence the child classes can only use them through accessor and mutator methods.

Consider a three-dimensional (3-D) geometric shape as a concept. Any such 3-D shape will have a volume and surface area, but until you know the nature of the shape and its attribute dimensions, these will be abstract in nature. Design and implement an inheritance hierarchy starting with a 3-D shape, then a set of at least three derived classes that define regular 3-D shapes such as a cube, sphere, cylinder, and so on. Include with your submission a UML class diagram showing the design. Any general 3-D shape will have a name, but few other attributes. For each derived shape, store fundamental attribute data about its dimensions, and provide methods to access and modify this data. In addition, provide appropriate methods to compute each shape’s volume and surface area. For example, a cube has a volume of s3 where s is the length of a side, whereas a sphere has a volume of 4πr3/3 where r is the radius. In terms of style, every class should have constructors and a toString() method that…

In this lab, you will practice defining and using interface, abstract class, abstract methods , superclass and subclass. You will write an inheritance hierarchy of three-dimensional shapes. Make a top-level shape interface that has methods for getting information such as the volume and surface area of a three-dimensional shape. Then make classes and subclasses that implement various shapes such as spheres, cylinders. You will also place common behavior in superclasses whenever possible, and use abstract classes as appropriate. Add methods to the subclasses to represent the unique behavior of each three-dimensional shape, such as a method to get a sphere’s radius. You need to figure out the formulas to calculate the area, surface area and volume for different shapes.1. Use NetBeans IDE to do the following: a. Start NetBeans.b. Please create a new project in a folder in your H: drive or your own flash drive and name your new project as:COSC241<your section number>_<your…

Develop an inheritance hierarchy based upon a Polygon class that has abstract methods area( ) and perimeter( ), and three instance variables of type int (number of dimensions), float (value of perimeter), and float (value of area). Your class must include a constructor method that initializes the int variable to an appropriate value. Implement classes Triangle, Quadrilateral, Pentagon, Hexagon, and Octagon extend this base class (Polygon), with the obvious meanings for the area( ) and perimeter( ) methods. Also implement classes, IsoscelesTriangle, EquilateralTriangle, Rectangle, and Square, that have the appropriate inheritance relationships. Finally, write a simple program (to test your classes), that allows users to create polygons of the various types and input their geometric dimensions, and the program then outputs their area and perimeter. Allow users to input polygons by specifying their number of dimensions and be able to test if two such polygons are similar ((by including…

Javascript Create an object, Gremlin, that extends the Monster interface and takes the same argument language. Gremlins inherits how a monster eats. Gremlins speaks differently. Gremlins replace each word in a sentence with its only known language, "gar". For example, if the sentence is "I like chicken", the speak() method will turn it into "gar gar gar". class Monster { constructor(language){ this.language = language; this.stomach = Array(); } // takes a food_item STRING and returns everything eaten so far ARRAY eat(food_item) { this.stomach.push(food_item); }   // takes in a sentence STRING and returns the passed in sentence STRING with no change speak(sentence) { returnsentence; }   }

• Create two subclasses for checking and saving accounts.A checking account has an overdraft limit, but a savings account cannot be overdrawn. Draw the UML diagram for the classes and then implement them. Write a test program that creates objects of Account, SavingsAccount, and CheckingAccount and invokes their toString() methods.
