True or False, the below method is a good example of a toString() method for the below class: public class Dog { private String name; private String breed; private int age; @Override public String toString() { return "Name: " + name + "\nBreed: " + breed + "\nAge: + age; } //other member methods go here }

True or False, the below method is a good example of a toString() method for the below class: public class Dog { private String name; private String breed; private int age; @Override public String toString() { return "Name: " + name + "\nBreed: " + breed + "\nAge: + age; } //other member methods go here }

*using java* Create a class AnimalCreate a class Cat, and a class Dog, and a class Bearded Dragon which extend Animal. Add to your Animal class: Member: name Methods: Public Animal(String name) //constructor public void makesSound()with the implementation printing out a generic animal sound. Next, override (add) the makesSound()method to your Cat and Dog class, with the implementation specific to each animal (i.e, cat says purr..). Do not override the makesSound() for your Dragon (bearded dragons don’t make sounds!)Note, you’ll also need a constructor in each of your subclasses which calls super(name) to initialize the common ‘name’ member of Animal. --- Next (in your test harness) create a List of different Animals ( a couple cats, a dog, a dragon... ) and add these Animals to your list. Iterate through your list & call makeSound on each. ( you should observe the implementation of the makeSound() method called will be: cat -> from Cat class, dog-> from Dog class,…
Write the complete equals method (including the method header) for the Appliance class. Two appliance objects are logically equivalent if they have the same description (ignoring capitalization), id (ignoring capitalization), and price. As an example, the two appliances with this data would be considered equal: "dishwasher", "ABC123", 999"DISHWASHER", "abc123", 999 Here is the appliance class: public class Appliance { private String description; private String id; private int price; // using an int for simplicity public Appliance(String description, String id, int price) { this.description = description; this.id = id; this.price = price; } public String getDescription() { return description; } public void setDescription(String description) { this.description = description; } public String getId() { return id; } public void setId(String id) { this.id = id; } public int getPrice() {…
In the following there are two classes, Employee and Manager. Manager is a subclass of Employee. The implementation of Employee class is given (Note: no getter methods are provided, so you are not able to access instance variables through getter methods in the subclass). The skeleton of the Manager class definition is given. Complete the constructor method, and the toString method for the subclass (see the details below). public class Employee { private String name; private double salary; // Make an employee with a given name and salary. public Employee(String aName, double aSalary) { name = aName; salary = aSalary; } // Provide a string description of an employee. public String toString() { return "Name: " + name + "\tSalary: " + salary; } } public class Manager extends Employee { private String department; // Make a manager with a given name, salary, and department. public Manager(String name, double salary, String department) { // put your code below } // Provide a string…

In this exercise, you have to calculate the student's total marks using the concept of Classes Problem Statement# Write a Java class called Student with ● private fields: ○ name(String type) ○ mark1 and mark2 (double type) And methods: ● getMarks(int markNumber), a method which should return mark1 if markNumber equals 1 and mark2 otherwise. ● calcTotal() method should take the two marks entered and return their sum. Also define two constructors: ● A default constructor that takes no parameters and initializes the values to zeros and null. ● A constructor that takes the three variables and sets them as the values of the appropriate fields. Input# Name of the student and the marks obtained in the first and second tests Output# Sum of both marks Sample Input# Student student = new Student("Jack", 60, 70); Sample Output# getMarks(1) => 60 getMarks(2) => 70 calcTotal() => 130.0 Part of solution class Student { // Define private fields here public Student() { // Write…

FOR JAVA Implement the following classes / abstract classes below. Monster abstract class which has health point (int), damage point (int), name (String), resistance rate (int) fields and following methods. – A constructor that takes the name as a parameter and sets the health and damage points to random numbers between 10 and 100. – isDead() method which returns true if hp is less than or equal to 0, and false otherwise. – fight() method which prints the applied damage after resistance (see below). WaterMonster class whose resistance rate is %20. For example, if the damage of an instance of this class is 100, the fight method should print 80. FireMonster class whose resistance rate is %10. SlicingMonster class whose resistance rate is %5.
