Use BlueJ to write a java program that complete the following parts: "Employee" class: Create a class Employee and perform the following: - Define private fields (Ename, Eage, Edepartment) as (String, int, and String) respectively. - Define a class variable Salarythat holds a constant value 10000. · Define a parameterized constructor of the class Employeeto initialize the values of (Ename, Eage, E_department) as they are received in the parameters. Your "fullName group "class. Create your class and perform the following: - Declare a HashMap of employees where the Hashmap holds employees' id strings as its keys, and the values are the objects that are created by the class Employee. - Create a method to add an employee into the HashMap. The method receives two parameters, the employee id and employee object. Create a method to lookup an employee in the HashMap by employee id. The method receives the lookup key in the parameter.

First, you need to design, code in Java, test and document a base class, Student. The Student class will have the following information, and all of these should be defined as Private: A first name (given name) A last name (family name/surname) Student number (ID) – an integer number (of type long) The Student class will have at least the following constructors and methods: (i) two constructors - one without any parameters (the default constructor), and one with parameters to give initial values to all the instance variables of Student. (ii) only necessary set and get methods for a valid class design. (iii) a reportGrade method, which you have nothing to report here, you can just print to the screen a message “There is no grade here.”. This method will be overridden in the respective child classes. (iv) an equals method which compares two student objects and returns true if they have the same student number (ID), otherwise it returns false. You may add other…
In Java, Write a line of code that performs each of the following tasks : (a) Call superclass Employee's toString method from subclass Pieceworker's toString method. (b)Specify that class Pieceworker inherits from class Employee. (c) Call superclass Employee's constructor from subclass Pieceworker's constructor - assume that the superclass constructor receives three strings representing the first name, last name and social security number.

code to To achieve encapsulation in Java: Declare the variables of a class as private.Provide public setter and getter methods to modify and view the variables values.
An employee has a name, phone number and salary. A coach is a person with a senitority status, one of: junior, lead, and senior. Define the possible status values as constants. A staff is a person with a job title and job descrption. Your programming task is to Implement as abstract class named Employee and two subclass name Coach and Staff in Java as defined above Provide constructors for classes to initalize private variable Override the toString() method in each of the classes in task 1 to display the class name and the person's name Write an application to create objects of type Coach and Staff and print the person's name and the class name of the objects
Note: Write a Java program given below Question # 1: Define a class for Students with field name, age, marks. Define getter and setter for all the fields. In the setter method, if age is less than 0, print that Age is less than zero. Similarly, if marks is less than zero or greater than 100, print in correct marks and don’t assign marks to member variable. In the Test class, create student’s object and assign the marks and age to appropriate values. Try assigning incorrect values to check if getter and setter methods work as expected.
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…

Define a class named Doctor whose objects are records for a clinic’s doctors. Derive this class from the class Person given in Listing 8.1. A Doctor record has the doctor’s name—defined in the class Person—a specialty as a string (for example Pediatrician, Obstetrician, General Practitioner, and so on), and an office-visit fee (use the type double). Give your class a reasonable complement of constructors and accessor methods, and an equals method as well. Write a driver program to test all yourmethods.
