Create a PhoneListing class that uses the Name class for one of its instance variables. Remember the instance data in the Name class is private to the class and must be accessed through its methods.Add additional instance variables to the PhoneListing class for the phone number. The phone number should be broken down into three parts, area code, city code, and local code.Create all appropriate methods for the new class, including the following three methods: equals(PhoneListing):boolean, an equality of state method that returns true if the objects contain the same name and phone number. compareTo(PhoneListing):int, a comparison method that returns -1 if the calling PhoneListing object should precede the argument PhoneListing object, 1 if the calling PhoneListing object should come after the argument PhoneListing object, and a 0 if they are equal. Use last, first, middle, phone number as the ordering values. example:Adams, Alex, Henry, (609)473-2101 Adams, George, Henry, (509)373-1101…
(Java) Question 2 Explain the answer step-by-step and include verbal explanation. Thank you! What is the difference between overriding a method and overloading a method? Select the correct option next to each statement, or select both options if the statement is true for both. Both methods have the same name: Overriding / Overloading Both methods have the same signature: Overriding / Overloading Both methods are defined in the same class: Overriding / Overloading
ANSWER IN JAVA Create a class called Date that includes three instance variables-a month (type int), a day (type int) and a year (type int). Provide a constructor that initializes the three instance variables and assumes that the values provided are correct. Provide a set and a get method for each instance variable. Provide a method displayDate that displays the month, day and year separated by forward slashes (/). Add a main method to the class that demonstrates class Date's capabilities.

Change the Fraction class so that its instance variables (numerator and denominator) are hidden (i.e. private). Check that the client class (after this change) will now not compile. Why does it not compile? Provide the changes to the Fraction class and the TestFraction class such that the program can work with the private instance variables by implementing appropriate accessor and mutator methods. import java.util.Scanner;//test programpublic class testfraction{public static void main(String[] args) {//create a Scanner objectScanner in = new Scanner(System.in);//create new fractionFraction frac = new Fraction();//declare numerator and denominatorint n=1,d;System.out.print("Enter Fraction's Numerator: ");//input numeratorn = in.nextInt();System.out.print("Enter Fraction's Denominator: ");//input denominatord = in.nextInt();//loop execute until the numerator is negativewhile(n>=0){//call input with n and dfrac.input(n, d);//call displayfrac.display();System.out.print("Enter…

Create a Java class called "Person" with the following instance variables: a String variable named "name" an integer variable named "age" Create a constructor for the Person class that takes in a String parameter "name" and an integer parameter "age" and initializes the instance variables with those values. Create a method in the Person class called "introduce" that returns a String introducing the person, including their name and age. In the main method, create a new instance of the Person class and pass in the values "John" and 30 for the name and age parameters, respectively. Then, call the "introduce" method on the new instance and output the result to the console. Output: "Hi, my name is John and I am 30 years old." Finally, create another instance of the Person class with a different name and age, and call the "introduce" method on that instance as well. Output: "Hi, my name is Jane and I am 25 years old."

(1) Add an __init__ method to the Widget class below. Each object of type Widget should have an instance variable called name and an instance variable called cost that represents a cost in dollars; those values are passed in when an object of type Widget is initialized. (2) Add a method to class Widget called is_cheap that returns True if the cost is less than $10, and False otherwise. (3) Add proper doctrings along with two examples for each method. You may use the Sample Usage code given below in your work.
You are going to be working with class Rational which defines rational number objects. A rational number is a number that can be written as a fraction. A rational number consists of a numerator and a denominator (which cannot be 0). Rational numbers also have the ability to be displayed in an original form, decimal form or reduced form. You are going to be completing various object methods to perform the tasks previously list. You are to begin with the Rational Class and RationalTest classes provided. Make all modifications outlined in the point values below. Pay close attention to the names of the attributes, methods and return values. You are given starter files and the test files necessary. Only modify class Rational and keep the function headers provided to you for all of Part 1. You will need to add your own methods for Part 2. Part 1a This version requires that you complete the constructor, getOriginal(), and getDecimal() methods of class Rational. Constructor: at this stage…
