- Create a Class Student in which we have three instance variables emp_name, emp_id, and Salary. Write getter and setters for each instance variable. Write another Display method that displays the record of Employee. In Main create five Employee’s Objects. Set their values as required and display as well. In the end Display top three employees with respect to Salary (Display those who have more Salary among all).Java - Constructors Create a class named Book that has the following attributes: Publisher - String Year Published - Integer Price - Double Title - String Create a constructor for the class Book that has the parameters from the attributes of the class. After, create a method for the class that displays all attributes. Ask the user for inputs for the attributes and use the constructor to create the object. Lastly, print the values of the attributes. Inputs 1. Publisher 2. Year Published 3. Price 4. Book Title XYZ Publishing 2020 1000.00 How to Win? Sample Output Published: ABC Publishing Year Published: 2022 Price: 150.00 Book Title: Stooping too low Stooping too low is published by ABC Publishing on 2022. It sells at the price of Php150.00.a. Write a FractionDemo program that instantiates several Fraction objects and demonstrates that their methods work correctly. Create a Fraction class with fields that hold a whole number, a numerator, and a denominator. In addition: Create properties for each field. The set access or for the denominator should not allow a 0 value; the value defaults to 1. Add three constructors. One takes three parameters for a whole number, numerator, and denominator. Another accepts two parameters for the numerator and denominator; when this constructor is used, the whole number value is 0. The last constructor is parameterless; it sets the whole number and numerator to 0 and the denominator to 1. (After construction, Fractions do not have to be reduced to proper form. For example, even though 3/9 could be reduced to 1/3, your constructors do not have to perform this task.) Add a Reduce() method that reduces a Fraction if it is in improper form. For example, 2/4 should be reduced to 1/2. Add an operator+() method that adds two Fractions. To add two fractions, first eliminate any whole number part of the value. For example, 2 1/4 becomes 9/4 and 1 3/5 becomes 8/5. Find a common denominator and convert the fractions to it. For example, when adding 9/4 and 8/5, you can convert them to 45/20 and 32/20. Then you can add the numerators, giving 77/20. Finally, call the Reduce() method to reduce the result, restoring any whole number value so the fractional part of the number is less than 1. For example, 77/20 becomes 3 17/20. Include a function that returns a string that contains a Fraction in the usual display format—the whole number, a space, the numerator, a slash (D, and a denominator. When the whole number is 0, just the Fraction part of the value should be displayed (for example, 1/2 instead of 0 1/2). If the numerator is 0, just the whole number should be displayed (for example, 2 instead of 2 0/3). b. Add an operator*() method to the Fraction class created in Exercise 11a so that it correctly multiplies two Fractions. The result should be in proper, reduced format. Demonstrate that the method works correctly in a program named FractionDemo2. c. Write a program named FractionDem03 that includes an array of four Fractions. Prompt the user for values for each. Display every possible combination of addition results and every possible combination of multiplication results for each Fraction pair (that is, each type will have 16 results).
- 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 Create a class named "Identity" class with attributes: name, age, city and gender. Choose your own data type (int, string etc.). Create 4 different methods; eat, study, sleep and play. Make each of them Print something like “I am sleeping”.In main driver class create object of a class with default constructor. Create two objects as shown in the image. Then call all methods of a class (eat, study, sleep and play).Add toString method displaying all attributes (name, age, city and gender). Add setters and getters for each attribute. Print each attributes from main program with getters.Write a Java program that manages students and their marks. Create a class called Student with the following attributes and methods: studentId name grades[] gradeCount getStudentId() addGrade(double grade) getAverageGrade() hasGradesAbove(double threshold) displayStudentInfo() Create two subclasses of Student: RegularStudent and HonorsStudent. The RegularStudent class should have an additional attribute: major. The HonorsStudent class should have an additional attribute: honorsProgram. Both subclasses should override the displayStudentInfo() method. In the Main class, create instances of the RegularStudent and HonorsStudent classes, and prompt the user to enter the details for each student. Add grades to each student by prompting the user to enter the grades. Show all screenshots of all outcomes
- Create a class Rectangle with attributes length and width with are variables, each ofwhich defaults to 1. Provide methods that calculate the rectangle’s perimeter and area.It has set and get methods for both length and width. The set methods should verify thatlength and width are each floating-point numbers (double datatype) larger than 0.0 andless than 20.0. Write a Test class to test all the methods from class Rectangle.RectangleTest.java source file should looks like this:class Rectangle{//data fileds//methods}//end Rectangle classpublic class RectangleTest{ //main method}//end RectangleTest classWrite a class named Car that has the following data attributes in pyton:a. __year_model (for the car’s year model)__make (for the make of the car)__speed (for the car’s current speed)The Car class should have an __init__ method that accepts the car’s year model and make as arguments. These values should be assigned to the object’s __year_model and __make data attributes. It should also assign 0 to the __speed data attribute.The class should also have the following methods:b. Accelerate: The accelerate method should add 5 to the speed data attribute each time it is called.Brake: The brake method should subtract 5 from the speed data attribute each time it is called.get_speed: The get_speed method should return the current speedCreate the following classes (each in a separate .jave file)- Product, Book, Car and ProductTest Product Class has an instance variable: int id and a print() method that displays the String" Product- id: xxx"Product Class has one Constructor for setting value for Id.Book Class inherits from Product.
