A solution is placed in the "solution" section to help you, but we would suggest you try to solve it on your own first. Implement the constructor Dell(String name) of the Derived Class Dell which takes a string, name. We have already implemented the Base Class Laptop with the member function getName() and a parameterized constructor. Input# Laptop name is being passed through the parameterized constructor. Output# getName() method is returing Laptop name. Sample Input# Dell dell = new Dell("Dell Inspiron"); Sample Output# "Dell Inspiron"Use the following partial class definitions to answer the question: public class A1 { public int x; private int y; protected int z; } public class A2 extends A1 { protected int a; private int b; } public class A3 extends A2 { private int q; } Which of the following lists of instance data are accessible in A3? Group of answer choices x, y, z, a, b, q a, b, q a, q x, z, a, q x, a, q

In a main, build an object of that class, and print out the object using System.out.println(). Notice that this simply reports the memory address of the object in question, and we’d like to do something more useful. To replace (or override) the toString (or equals) function. Now, build a toString function that prints out the make, model, and odometer reading for a vehicle object. public class Car { //instance variables private int odometer; private String make; private String model; //overloading //constructors public Car(int odometer,String make, String model) { this.odometer = odometer; this.make = make; this.model = model; } public Car(String make, String model) { this.make = make; this.model = model; } public Car(String make) { this.make = make; } /* *getter & setter methods */ public int getOdometer() { return odometer; } public void…Q2: Consider the following statements: public class YClass { private int a; private int b; public void one() { } public void two(int x, int y); { } public YClass() { } } class XClass extends YClass { private int z; public void one() { } public XClass() { } } YClass yObject; XClass xObject; Write the definition of the default constructor of YClass so that the instance variables of YClass are initialized to 0.

- Subject: Java Programming Hi Expert Sir, this (A, B) is one question...... please read and solve it carefully. and Don't submit the wrong answer. It's very important to me.... thank you Write a program to calculate the midpoint of two 2D coordinate points. A) Among them, the Point class represents two-dimensional coordinate points and has private member variables x and y, representing the values of the abscissa and ordinate, initialized by the constructor. B) Four methods setX (), getX (), setY (), and getY () are used to set and obtain the coordinates. In addition, a member method midPoint (Point p), which takes a Point object as a parameter, calculates the midpoint of the two coordinates and returns a new two-dimensional point. It is required to reflect the encapsulation characteristics in the program. Instantiate two two-dimensional points (4, 5) and (6, 8) in the main function of the class Test. Calculate the midpoint of the two by calling the midPoint of one of them and return…I need help figuring out what is wrong with my code. class employee:def __init__(self, name, age, rank_ID):self.name = nameself.age = ageself.rank_ID = rank_IDdef is_higher_rank(self, employee):if self == employee:return "These employees are both the same rank!"elif self.rank_ID < employee.rank_ID:return self.name + " is senior rank than " + employee.name + "!"else:return employee.name + " is senior in rank than " + self.name + "!"def __eq__(self, employee):return self.rank_ID == employee.rank_IDdef __repr__(self):rep = ("Employee Name: " + str(self.name) + "\n" + "Age: " + str(self.age) + "\n" + "ID: "+ str(self.rank_ID) + "\n")return repemployee1 = employee("Michael", 45, 12345)employee2 = employee("Dwight", 40, 23456)employee3 = employee("Pam", 30, 34567)employee4 = employee("Jim", 35, 12345)def test_is_higher_rank():assert employee1.is_higher_rank(employee4) == 'These employees ''These employees are both the same rank!', "Should be the same"assert…Consider the following class. 1 public class Duck { 2 private String name; 3 private int age; 4 5 public Duck(String name, int age) { 6 this.name = name; 7 this.age = age; 8 } 9 10 public Duck(String name) { 11 this.name = name; 12 this.age = 10; 13 } 14 15 public void setNewName(String name) { 16 this.name = name; 17 } 18 19 ... 20 } Write the values of the name and age fields of both duck1 and duck2 objects after having executed the following code snippet: 1 Duck duck1 = new Duck("Oncle Scrooge"); 2 Duck duck2 = new Duck("Huey", 20); 3 duck1.setNewName("Dewey");
