IN JAVA Design and code a class hierarchy that demonstrates your understanding of inheritance and polymorphism. Your hierarchy should contain at least 5 classes and one driver program that instantiates each type of object and runs multiple methods on those objects. Inheritance and Polymorphism must be apparent in the project. Please keep in mind that polymorphism was in chapter 37, so you will need to have read both chapters to understand what goes into this project. Bonus if you add...

JAVA: Quadrilateral Inheritance Hierarchy Write an inheritance hierarchy for classes Quadrilateral, Parallelogram, Rectangle, and Square. Use Quadrilateral as the superclass of the hierarchy. Create and use a Point class to represent the points in each shape. Make the hierarchy as deep as possible, i.e. more than two levels. Specify the instance variables and methods for each class. The private instance variables of Quadrilateral should be the x-y coordinate pairs for the four endpoints of the Quadrilateral. A program that instantiates...

Lab 1: InheritanceTest Write a program called InheritanceTest1.java to support an inheritance hierarchy for class Point–Square–Cube. Use Point as the superclass of the hierarchy. Specify the instance variables and methods for each class. The private data of Point should be the x-y coordinates, the private data of Square should be the sideLength, and the private data of Cube should be depth. Provide applicable accessor methods, mutator methods, toString() methods, area() method, and volume() method to all classes. Write a program...

Use inheritance to create a hierarchy of Exception classes -- EndOfSentenceException, PunctuationException, and CommaException. EndOfSentenceException is the parent class to PunctuationException, which is the parent class to CommaException. Test your classes in a Driver class with a main method that asks the user to input a sentence. If the sentence ends in anything except a period (.), exclamation point (!), or question mark (?), the program should throw a PunctuationException. If the sentence specifically ends in a comma, the program...
