- Computer Science : Using Java implement the following lab experiment using HashMap. Create a class Product with following details Instance Variable: pid(int), product_name(String), price (double) Overloaded Constructor toString() method Create another class called TestProductMap and implement the following in the main method: Create 10 products Create HashMap that accepts key integer and value product. Ex: HashMap<int, Product> Add all the product to the HashMap, every product key is 1, 2, 3 … so on Display the HashMap Add duplicate product to the map with different key Get the duplicate product that you just added to the list and display it. Delete a product from the HashMap. Display the HashMapIn main.py define the Student class that has two attributes: name and gpa Implement the following instance methods: • A constructor that sets name to "Louie" and gpa to 1.0 set_name(self, name) - set student's name to parameter name get_name(self) - return student's name set_gpa(self, gpa) - set student's gpa to parameter gpa get_gpa(self) - return student's gpa Ex. If a new Student object is created, the default output is: Louie/1.0 Ex. If the student's name is set to "Felix" and the gpa is set to 3.7, the output becomes: Felix/3.7Write the Circle class:• A Circle has a radius – Add instance variable – 2 constructors – one should be the default or no args – Add accessor and mutator method for each instance variable – Add methods to calculate Area, Perimeter, and Diameter TestCircle Create a Circle with the radius Print the radius using the getters Print the Circle’s area, circumference, and diameter Change the circle’s radius Reprint the information
- Write PHP code for a class that contains three private variables and a method that consumes those variables and which displays an output. One of the variables must be a date/time class instance and another variable must be an arrayModified Circle class and test file: Add a new attribute for color (or any other new attribute) Add get/set methods for this new instance variable, including data validation in set method (assuming background is black, i.e. circle color can't be black, reset to any non-black color if black is entered ). Add a new constructor to pass the color attribute as an argument. Add an instance method to display all properties of a Circle object. Create 2 objects using different constructors in test file, with invalid data. Use this test java file test java file: class CircleTest{ public static void main(String[] args){ int num = 10; Circle c1 = new Circle(0.001); Circle c2 = new Circle("black", -9); c1.display(); c2.display(); c1.setRadius( -1); c1.setColor("black"); c1.display(); }}import components.naturalnumber.NaturalNumber;import components.naturalnumber.NaturalNumber2;import components.simplewriter.SimpleWriter;import components.simplewriter.SimpleWriter1L; /*** Program with implementation of {@code NaturalNumber} secondary operation* {@code root} implemented as static method.** @author Mati Desissa**/public final class NaturalNumberRoot { /*** Private constructor so this utility class cannot be instantiated.*/private NaturalNumberRoot() {} /*** Updates {@code n} to the {@code r}-th root of its incoming value.** @param n* the number whose root to compute* @param r* root* @updates n* @requires r >= 2* @ensures n ^ (r) <= #n < (n + 1) ^ (r)*/public static void root(NaturalNumber n, int r) {assert n != null : "Violation of: n is not null";assert r >= 2 : "Violation of: r >= 2"; double lowEnough = 0;double tooHigh = n.toInt();double power = 1.0 / r;double value = Math.pow(tooHigh, power);double guess = (1.0) * tooHigh / 2; while ((int) guess !=…
