- Your task is to implement the Name class. This class represents a person's name. It has three instance variables representing the first, last and middle name (all are string variables). A character instance variable representing a separator (to be used for printing purposes) is also part of the class. The only valid separators we can have are a comma (,), a dash (-), and a pound symbol (#). In addition, a nickname instance variable (string) keeps track of the person's nickname (if any). The output have to match with the image. Write code in JavaScriptYour task is to implement the Name class. This class represents a person's name.

- Given the following class. (JAVA) public class FamilyMember { public String drink( ) {return “cup”;} public String eat( ) {return “fork”;} } Write a Baby class that is derived from the FamilyMember class. The Baby class has an instance variable for the age, a default constructor, and a constructor that accepts an integer. Include any other necessary methods. If a baby is older than 3 years, print that “it eats with its fork”; otherwise, “it eats with its hands”.Computer Science In Java, create a class Die representing a die to roll randomly. -Give Die a public final static int FACES, representing how many faces all dice will have for this run of the program. -In a static block, choose a value for FACES that is randomly chosen from the options 4, 6, 8, 10, 12, and 20. -Give Die an instance variable current, representing the last value it rolled. (cannot be less than 1 or more than FACES) -Give Die int instance variables maxCount and minCount. (cannot be negative) -Give Die a method roll that randomly sets current to a value between 1 and FACES. If the die rolls a 1, increase minCount, if the die rolls FACES, increase maxCount. -Give Die a static method sumDice, which takes a variable length parameter list of Dies and returns the sum of all their current values. -Give Die a static method sameDice, which takes a variable length parameter list of Dies, and returns true only if all of them have the same current value. Do not compare…Using JAVA Language Consider a Billing class that implements an interface Payable having a method getTotalPaymentAmount(). Besides this, you have a Doctor class with private instance variables (docID, docName, and docFee) and a public getDoc() method, Patient class with private instance variables (pName, pID, pDisease), Medicine class with private instance variables (medID, medName, medQty, medPrice), and MedicalTest class with private instance variables (testID, testName, testPrice). Each of these classes has the toString() method to display the information of its object. The Billing class is having "Has A" relationship with the other four classes (Doctor, Patient, Medicine, and MedicalTest) mentioned above. The getPaymentAmount() method of Billing class returns the total billing amount that includes doc fee, medicine cost, and medical test fee that a patient has to pay. After implementing these classes, you are required to do the following in the driver class: Create an ArrayList of…
- Write a java program to create a class Employee which contains member variables as name (String object)empid (Integer object)salary (Float object)age (Integer object)Define a default as well as a parameterized constructor to initialize member variables with default and specified values respectively. Define and overload a method search as defined below boolean search (Employee e[ ], String name) To search an employee with name in an array of employee objects, if found return true, else false.boolean search (Employee e[ ], Integer empid) To search an employee with the empid in an array of employee objects, if found return true, else false.Also define another method to get the name of employee having highest salary in a set of employees. String getHighestSalary(Employee e[ ]) To return the name of the employee with highest salary in an array of employee objects.Input: At least 3 employee details like name, empid, salary and age.Name of employee to searchId of employee to searchOutput:…i have a parent class called Person containing the name and ID number of students and i need to write the program for a child class named student that extends from the parent class and also adds two more attributes below is a copy of my Parent class public class Person{ private String name; private int id; public Person( ) { name = "not defined"; id = 0; } public Person(String newName, int newId ) { name = newName; id = newId; } public String getName( ) { return name; } public int getId( ) { return id; } public void setName(String newName) { name = newName; } public void setId(int newId) { id = newId; } public void set(String newName, int newId) { name = newName; id = newId; } public String toString( ) { return "Name = " + name + "ID is " + id;…Write a Java program for a class named Baby. A Baby has a name of type String and an ageof type integer.Supply two constructors: one will be the default constructor, that just setsdefault values for the name and age; the second constructor will take twoparameters, a string to set the name and an integer to set the age. Also, supplymethods for setting the name, setting the age, getting the name and getting theage.The class should not contain I/O methods; input of values to the instancevariables must be done with a set method or constructor, output of values fromthe instance variables must be done with get methods. The set method for thename instance variable should ensure that the input is not empty or containwhitespaces (otherwise set a default value). The set method for the ageinstance variable should validate the input to be between 1 and 4 inclusive(otherwise set a default value).Give Java code for an equals method for the Baby class. Babies count asbeing the same (i.e. equal) if…
- An arithmetic progression is a sequence of numbers such that the difference between the consecutive terms is constant. For instance, the sequence 5, 7, 9, 11, 13, 15 is an arithmetic progression with a common difference of 2.Given the class IntNumber:1 public class IntNumber2 {3 public final int value;45 public IntNumber(int number) {6 this.value = number;7 }8 }where value is an immutable field, that can be directly accessed (public), implement a class called ArithmeticProgressionthat implements the following methods:•1 public static IntNumber getArithmeticProgressionDifference(ArrayList<IntNumber> list)which returns the difference between terms of the arithmetic progression (as an object of type IntNumber) if thevalues of the IntNumber objects are an arithmetic progression. The method returns null in any other case.•1 public static void printIsArithmeticProgression(ArrayList<IntNumber> list)which prints on the console:The list is an arithmetic progression with difference =…Java program Make a class Employee with a name and salary. Make a class Manager inherit from Employee. Add an instance variable, named department, of type String. Supply a method toString that prints the manager’s name, department, and salary. Make a class Executive inherit from Manager. Supply appropriate toString methods for all classes. Supply a test program that tests these classes and methods.This question concerns writing a Student class to model a student's name, composed of a first name, middle name and last name. The Student class should meet the following specification:Class StudentA Student object represents a student. A student has a first name, middle name and last name.Methodspublic void setNames(String first, String middle, String last)// Set the first, middle and last names of this Student object.public String getFullName()// Obtain the full name of this Student with the middle name converted to an initial only.2Thinking of the problem in terms of testing, there are three requirements that must be met:1. The setNames() method sets the names stored in the object i.e. the values of firstName, middleName, lastName.2. The getFullName() method obtains the name of the student with the middle name converted to an initial only.3. The getFullName() method does not change anything – i.e. it does not modify the values of firstName, middleName, lastNameHINT: To start your…
