Given the following code snippet: for(Circle ccircles) { System.out.printin(c.toString(); Select one: O a. The compiler will call the toString() method of the parent class of class Circle if it is not defined in the Circle class O b. All of these O .The compiler will report an error if the toString( ) method is not defined in the Circle class O d. The compiler will report an error if the toString() method is not overridden in the Circle class

Please in pyth coding with correct indentation 4a) Given that you have a Liquid class that can be initialized with any amount of gallons, liters, ounces, etc, write the first line of the method that will allow you to add together two Liquid objects using operator overloading. Again, write ONLY the first line (method definition) – you do NOT have to write the entire method. 4b) Given that you have L1 and L2 which are instances of the Liquid class, write a line of code that uses operator overloading to add them together and assign the result to L3.
In this lab, you will construct a class called QuadraticSolver that will compute the real roots of a quadratic function (�(�) = ��! + �� + �).The class will implement the following methods.• A default constructor that initializes a legitimate quadratic function.• An overloaded constructor that takes the values of a, b, and c in the function �(�) = ��! +�� + �. This method throws a QuadraticException in the case where the input does not define a quadratic function.• A method that computes the discriminant (�! − 4��).• Boolean methods determining whether the solutions of the quadratic equation ��! + �� + � =0 have real or non-real solutions.• Two methods, one for each real root of the equation ��! + �� + � = 0. Each method will throw a NonRealException when the root is a non-real value.• A toString method that (reasonably) prints the quadratic function.The classes QuadraticException and NonRealException have been provided. Implement a main method in a separate class to test your…
Please help me with this , I am stuck ! PLEASE WRITE IT IN C++ Thanks 1) bagUnion: The union of two bags is a new bag containing the combined contents of the original two bags. Design and specify a method union for the ArrayBag that returns as a new bag the union of the bag receiving the call to the method and the bag that is the method's parameter. The method signature (which should appear in the .h file and be implemented in the .cpp file is: ArrayBag<T> bagUnion(const ArrayBag<T> &otherBag) const; This method would be called in main() with: ArrayBag<int> bag1u2 = bag1.bagUnion(bag2); Note that the union of two bags might contain duplicate items. For example, if object x occurs five times in one bag and twice in another, the union of these bags contains x seven times. The union does not affect the contents of the original bags. Here is the main file: #include <cstdlib>#include <iostream>#include "ArrayBag.h"using namespace std; template…

Use this exercise to test your code that you wrote in the previous exercise. Problem Class In this exercise, you are going to create the Problem class. The Problem class is used to help simulate a math fact, for example: 2 + 5 = Your class needs to contain two constructors, one that takes String, int, int that represents the operator sign(+, -, *, or /), the minimum, and maximum values for the number range, and a second constructor that takes only a String that represents the operator sign. For the second constructor, the minimum should default to zero and the maximum to ten. Your Problem object should generate 2 random integers between the minimum and maximum values (inclusively). Each Problem object should only have one set of numbers that do not change. While you may include additional helper methods, two methods need to be available to the user. The first is the answer method that should return a double that represents the answer to the problem. The second is the toString that…
I need help with this. Thanks in advance It might not be reasonable to expect users to type long entries such as “oil change” accurately. Implement the CarCareChoice2 class so that as long as the user enters the first three characters of a service, the choice is considered valid. An example of the program is shown below: Enter selection:oil changetire rotationbattery checkbrake inspectionbatry checkbatry check price is $15 import java.util.*; public class CarCareChoice2 { // Modify the code below public static void main (String[] args) { Scanner input = new Scanner(System.in); boolean isMatch = false; String[] items = { "oil change", "tire rotation", "battery check", "brake inspection"}; int[] prices = {25, 22, 15, 5}; int x; int matchIndex = 0; String menu = "Enter selection:"; for(x = 0; x < items.length; ++x) menu += "\n " + items[x]; System.out.println(menu); String selection =…

The following code may, or may not, work. However the bigger issue is that it doesn't give good information to the end user. Assume that there is a Circle class, like we've defined in class before. Fix what problems you see, that could affect naming conventions, capitalization, and data output, and make sure the data output is clean for the end user. cout << "For Circle 1:" << endl; cout << c1.getArea() << endl; cout << c1.getx() << " " << c1.gety() << endl; cout << c1.getcolor() << endl; cout << endl << endl; This is the full question and it is c++

Write a public int method named initialNumberOfSticks which takes two int parameters named max_sticks and min_sticks and returns a random integer value between max_sticks and min_sticks (inclusive). You will create a new instance of the Random class and call it r. Use the nextInt method of r to a get random value within a desired range and use it to compute the value that will be returned. Your method must be a syntactically correct Java method.
Assume that you are applying “testing” and “inspection”, the two defect finding methods in the following buggy code example to find defects. Explain how “testing” and “inspection” differ in finding defects quickly and the efforts required for the example. public class Employee { private String id; private int name; private double salary; public Employee(String id,int name,double salary) { } public Employee() { } } Public class Customer { public static void main(String s[]) { Employee e1=new Employee(“10060OTU”, “S1”, 2000.50); Employee e2=new Employee(); System.out.println (“The salary of Employee S1 is”+ e1.salary); }
