- What are the corresponding wrapper classes for the following primitive types?
- int
- char
- boolean
- short
Step by step
Solved in 2 steps with 1 images
- 1- Write a class that allows you to define complex numbers in C++ and call it complex. The class contains two private members named real and img. It also has a constructor to initialize its members to values other than zero. Then, write a four methods that implement the basic mathematical operations (+,-.*/) for two complex numbers. 2- The purpose of the method resize() in the IntegerArray class below is to dynamically change the size of the IntegerArray instance. This methid is implemented as follows: 1. create a new array with the desired size 2. copy the data form the old to new one 3. delete the old data 4. Make the old data pointer points to the newly created data 5. update the size field your task is to write the resize() method based on the above five steps. #include int main() { IntegerArray a(2); using namespace std; class IntegerArray { public: a.data[0] = 4; a.data[1] = 2; int *data; a.resize(5); int size; cout size = size; } -IntegerArray() { delete[] data; } void…Which refers to the automatic conversion of a primitive type to the corresponding Wrapper class (e.g. automatic conversion of int to Integer)?Activity: Create a collection of objects using Java generics. use java to write code. Create a Month class that can accept integer or String data type as an argument. The parameter type will be decided at run time. For this exercise, we will use Month class to store integer and string values that contains 12 months. For example, the integer value of 12 corresponds to string value of “December.” Use the following minimal class definition for Month class. public class Month<T> { private T month; public void setMonth(T month); public T getMonth(); }; Create a new class, MonthApp. This new class will have main method, and will instantiate Month objects to store month indices and names. Here is an example using arrays. // defineMonth<Integer>[] monthsByNumber = new Month<>[12];Month<String>[] monthsByName = new Month<>[12];// adding valuesmonthsByNumber[0] = new Month<Integer>();monthsByNumber[0].setMonth(1);monthsByName[0] = new…
- USING C++ Random Number Guesser Write a derived class of the NumberGuesser class named RandomNumberGuesser. The derived class should override the behavior of the getCurrentGuess method. It may also add member data and its own constructor. It may also override the higher(), lower() and reset() methods as you see fit. I have written a NumberGuesser class to make things easier. // NumberGuesser.h #ifndef NUMBERGUESSER_H #define NUMBERGUESSER_H #include <iostream> class NumberGuesser { protected: int low; int originalLow; int high; int originalHigh; public: NumberGuesser(int l, int h) { low = originalLow = l; high = originalHigh = h; } virtual int getCurrentGuess() { return (high + low) / 2; } virtual void higher() { low = getCurrentGuess() + 1; } virtual void lower() { high = getCurrentGuess() - 1; } virtual void reset() { low = originalLow; high = originalHigh;…public class Product { private String name; private double cost; public Product(String n, double c) { name=n; cost=c; } public String getName() { return name; On the left is code for a class called Product. Fill in the blanks in the code on the right in order to create three appropriate Product instances and add them to the cart ArrayList. Use the output of the code, shown below the code, to guide you. } public double getCost() { return cost; } public String toString() { return (name + "$" + cost); } public static void addProducts (ArrayList c) { add(new Product("Shampoo", 13.89)); add(new Product("Bread",4.99)); add(new Product("Cereal", 7.49)); } public static void main(String[] args) { ArrayList cart = new ArrayList(); ddProducts (cart); for (Product p : cart) { System.out.println(p); } } Output: Shampoo $13.89 Bread $4.99 Cereal $7.49C++ Program: Random Number Guesser. Write a derived class of the NumberGuesser class named RandomNumberGuesser. The derived class should override the behavior of the getCurrentGuess method. It may also add member data and its own constructor. It may also override the higher(), lower() and reset() methods as you see fit. To get everyone started off on the same page I have written a NumberGuesser class. It is defined entirely in-line in the following file: NumberGuesser.h (Links to an external site.) https://fog.ccsf.edu/~mluttrel/cs110b/NumberGuesser.h In the current NumberGuesser class the getCurrentGuess() method returns the midpoint of the range of possible values. In your RandomNumberGuesser class the getCurrentGuess() method should return a randomly generated number in the range of possible values. Note that repeated calls to getCurrentGuess() should always return the same value for both classes if neither the higher() or the lower() functions are called. Consider the…
- Software Requirements: • Latest version of NetBeans IDE • Java Development Kit (JDK) 8 Procedure: 1. our progras from rhFactor non-static and private. Remove the constructor with two (2) parameters. 2o upply uncapsutation Make bloodType and 2. The names of the public setter and getter methods should be: • setBloodType() • setRhFactor() getBlood Type() getRhFactor() 3. Use the setter methods to accept user input. 4. Display the values by calling the getter methods. Sample Output: Enter blood type of patient: Enter the Rhesus factor (+ or -): O+ is added to the blood bank. Enter blood type of patient: B Enter the Rhesus factor (+ or -): B- is added to the blood bank.Q. Can I have a static method in a class that implements a data type?Exercise: Exercises Write a class named Octagon that extends GeometricObject and implements the Comparable and Cloneable interfaces. Assume all eight sides of the octagon are of equal length. The area can be computed using the following formula: The Octagon class has a private double data field named side with its getter and setter methods. The class has a no-arg constructor that creates an Octagon with side 0, and a constructor to create an Octagon with a specified side. Write a test program that creates an Octagon object with side value 5 and displays its area and perimeter. Create a new object using the clone method, and compare the two objects using the compareTo method. As far as classes go, the abstract GeometricObject class contains the abstract doubles getArea() and getPerimeter(). The programming language used in this exercise is Java, and it covers the Interfaces topic. I did get how most of the program should look like, but I'm facing trouble understanding a few…
- Novice: How can i access a main class objects from outside the function? / Better Alternative? If i have 4 Student objects how can i print the information for the specific object given one parameter about the class, like the students Idnumber. What i came up with was making a checkId void function that takes the user input and runs an if else chain checking if the Id belongs to student 1-4 then printing the details of that classes object with the void function print. ideally i would want the if-else chain in the checkId function to call the print( student1-4) class object but im not sure how to properly do that. i dont think this is the best way to go about it, if you have any recommendations or alternatives please help me out.Problem (Circle.java) Implement a class called Circle for representing a circle. The circle has two data members, a Point object representing the center of the circle and a float value representing the radius. Include appropriate constructors for your Circle class. Encapsulate it. Also include methods for finding the area and circumference of the circle. area = pi * radius * radius circumference = 2 * pi * radius. (You may use the static constant pi in the Math class) 5. Override the toString() and equals().Car herCar = new Car();Car hisCar = new Car(); Car myCar = hisCar;hisCar = null;myCar = herCar;herCar = hisCar; suppose the following obejexts created in the class car, How many "null reference" can you see in this code? How many "unreachable objects" can you see in this code, which will be subject to garbage collection? How many "active object reference" can you see in this code? How many "reachable objects" can you see in this code?
