9.1 (THE RECTANGLE CLASS) Following the example of the circle class in Section 9.20, design a class named Rectangle to represent a rectangle. The class contains: ▪ Two double data fields named width and height that specify the width and height of the rectangle. The default values are 1 for both width and height. ▪ A no-arg constructor that creates a default rectangle. ▪ A constructor that creates a rectangle with the specified width and height. ▪ A method named getArea () that returns the area of this rectangle. ▪ A method named getPerimeter () that returns the perimeter. Draw the UML diagram for the class then implement the class. Write a test program that creates two Rectangle objects-one with width 4 and height 40, and the other with width 3.5 and height 35.9. Display the width, height, area, and perimeter of each rectangle in this order.

10.11 C++ The base class Pet has protected data members petName, and petAge. The derived class Cat extends the Pet class and includes a private data member for catBreed. Complete main() to: create a generic pet and print information using PrintInfo(). create a Cat pet, use PrintInfo() to print information, and add a statement to print the cat's breed using the GetBreed() function. Ex. If the input is: Dobby 2 Kreacher 3 Scottish Fold the output is: Pet Information: Name: Dobby Age: 2 Pet Information: Name: Kreacher Age: 3 Breed: Scottish Fold

7.21 LAB: Triangle area comparison (classes) Given class Triangle (in files Triangle.h and Triangle.cpp), complete main() to read and set the base and height of triangle1 and of triangle2, determine which triangle's area is larger, and output that triangle's info, making use of Triangle's relevant member functions. Ex: If the input is: 3.0 4.0 4.0 5.0 where 3.0 is triangle1's base, 4.0 is triangle1's height, 4.0 is triangle2's base, and 5.0 is triangle2's height, the output is: Triangle with larger area: Base: 4.00 Height: 5.00 Area: 10.00

7.21 LAB: Random values use Java. In the file RandomNumbers.java, write a class called RandomNumbers that has three integer instance variables: var1, var2, and var3. Write getter method for each variable: getVar1(), getVar2() and getVar3(). Then write the following 2 instance methods: setRandomValues( ) - accepts a low and high integer values as parameters, and sets var1, var2, and var3 to random numbers (generated using the Random class) within the range of the low and high input values (inclusive). getRandomValues( ) - prints out the 3 random numbers in the format: "Random values: var1 var2 var3" Ex: If the input is: 15 20 the output may be: Random values: 17 15 19 where 17, 15, 19 can be any random numbers within 15 and 20 (inclusive). Note: When submitted, your program will be tested against different input range to verify if the three randomly generated values are within range. import java.util.Scanner; public class LabProgram {// main method used to test your codepublic…

11.17 (Bucket Sort) Use Python. Show the whole code input and output when done. A bucket sort begins with a one-dimensional array of positive integers to be sorted and a two-dimensional array of integers with rows indexed from 0 to 9 and columns indexed from 0 to n – 1, where n is the number of values to be sorted. Each row of the two-dimensional array is referred to as a bucket. Write a class named BucketSort containing a function called sort that operates as follows: a) Place each value of the one-dimensional array into a row of the bucket array, based on the value’s “ones” (rightmost) digit. For example, 97 is placed in row 7, 3 is placed in row 3, and 100 is placed in row 0. This procedure is called a distribution pass. b) Loop through the bucket array row by row, and copy the values back to the original array. This procedure is called a gathering pass. The new order of the preceding values in the one-dimensional array is 100, 3 and 97. c) Repeat this process for each subsequent…
13.5 (Enable GeometricObject comparable) Modify the GeometricObject class to implement the Comparable interface and define a static max method in the GeometricObject class for finding the larger of two GeometricObject class. Also, draw the UML diagram and implement the new GeometricObject class. Additionally, write a test program that use the max method to find the larger of two circle, the larger of two rectangles.
Description: In a hypothetical class, students take two midterms and an optional final. If a student takes the final and gets in it a better score than the lowest of the two midterm scores, then the lowest midterm score would be replaced by the comprehensive final score. The overall score will then be calculated by averaging the three test scores. If the student does not take the optional final, the overall score is calculated using only the two midterm scores. Students’ exam scores are included in the “Question1” tab in the attached worksheet. Empty data entries for the optional comprehensive final means that the student did not take the optional final. Tasks: Task 1: In Question1_Module, code a function that requires midterm1 score, midterm2 score, and comprehensive final as inputs and calculate the overall score per the description above. Task 2: In Question1_Module, code a Sub that uses the function coded in task 1 to fill column ‘I’ of the worksheet and link this…
