this is for java programming Please Use Comments I am not 100% sure if my code needs work, this code is for the geometric if you feel like you need to edit it please do :) Problem Description: Modify the GeometricObject class to implement the Comparable interface and define a static max method in the GeometricObject class for finding the larger (in area) of two GeometricObject objects. Draw the UML and implement the new GeometricObject class and its two subclasses...

Problem 3: Shape (10 points) (Software Design) Create an abstract class that represents a Shape and contains abstract method: area and perimeter. Create concrete classes: Circle, Rectangle, Triangle which extend the Shape class and implements the abstract methods. A circle has a radius, a rectangle has width and height, and a triangle has three sides. Software Architecture: The Shape class is the abstract super class and must be instantiated by one of its concrete subclasses: Circle, Rectangle, or...

Objectives: GUI Tasks: In Lab 4, you have completed a typical function of music player -- sorting song lists. In this assignment, you are asked to design a graphic user interface (GUI) for this function. To start, create a Java project named CS235A4_YourName. Then, copy the class Singer and class Song from finished Lab 4 and paste into the created project (src folder). Define another class TestSongGUI to implement a GUI application of sorting songs. Your application must provide the...

(Enable the Account class comparable & cloneable) @ Create ComparableAccount class inheritance from the Account class, and implemented the comparable and cloneable interfaces. Override the compareTo method to compare the balance of two accounts. Print the Account ID, balance and dataCreated information from the toString() method. Implements the cloneable interface and override the clone method to perform a deep copy on the dateCreated field. Write a driver program to create one array contains 5 ComparableAcccount objects (account #: 1001-1005, initial...

Step One This is the Measurable interface we saw in class; you will need to provide this class; this is it in its entirety (this is literally all you have to do for this step): public interface Measurable double getMeasure(); Step Two This is the Comparable interface that is a part of the standard Java library: public interface Comparable int compareTo (Object otherObject); Finish this class to represent a PiggyBank. A PiggyBank holds quarters, dimes, nickels, and pennies. You will...

In Lab 5, you completed the MyRectangle class, which is a simple representation of a rectangle. Review Lab 5 before completing this lab and retrieve the MyRectangle class that you completed for this lab, since you will need it again in this lab. Before starting this lab, edit your MyRectangle class in the following way: • change the declaration of your instance variables from private to protected This will enable access of these variables by your MySquare subclass. Here is...

Since we do not want to have to rewrite this code when the element type changes, this classes uses a Comparator to assist in ordering the elements. You will need to complete the siftUpComparator() and siftDownComparator() methods in the LinkedHeap Class. siftUp §Added element may violate heap-order property §siftUp() restores order starting at added node §Processing will continue working up the tree until: úFinds properly ordered node & parent úReaches the root (reaches node without parent) siftDown §Restores heap’s order...
