- 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).2-Create a class named 'Shape' with a method to print "This is This is shape".Then create two other classes named 'Rectangle', 'Circle' inheriting the Shapeclass, both having a method to print "This is rectangular shape" and "This iscircular shape" respectively. Create a subclass 'Square' of 'Rectangle' having amethod to print "Square is a rectangle". Now call the method of 'Shape' and'Rectangle' class by the object of 'Square' class.write a program using java Create a class named “Rectangle” having length and width as attribute.

- create a class rectangle with attributes length and width both encapsulated, each of which defaults to 1. provide methods that calculate the rectangle’s perimeter and area. write set and get methods for both length and width tp allow their access through behaviors. the set methods should verify that length and width are each floating-point numbers larger than 0.0 and less than 20.0. write a program to test class rectangleCreate a class Course, which has one field: String courseName Create the constructor, accessor, and mutator for the class. Then, in the main method of this class, create an instance of the class with the name "CST1201". Write an equivalent while statement to replace the following for statement for (int i=2; i<100; i=i+2) { System.out.println(i); }Java Question - Using the bottom code, create another class named "DigitalBook" as a subclass of the given "Book" class. Then, Make sure that the "DigitalBook" class contains two constructors: (1) one is the default constructor that takes no parameter, and (2) the other is a parameterized constructor that take 6 parameters. Be sure to use the “super” keyword in the constructors of the "DigitalBook" class. In the “main()” method of the “EX12_1” class, create four instances: “b1”, “b2”, d1”, and “d2”. Let “b1” and “b2” be the instances of the “Book” class, and let the “d1” and “d2” be the instance of the “DigitalBook” class. Be sure to use the specified constructor (as shown in attached picture) to initialize these instances. The Final Output is shown in the attached pictures. Please make sure that no errors show up in the Java Compiler when testing the code. Thank you. Add the following code to the "class Book" code (Below the ___ line). public class EX12_1{public static void…

Accounts have a balance and an annual interest rate. Include attributes in the Account class to reflect these. Write getters for both attributes and a setter for only the annual interest rate. Think about how real bank accounts work, you change your balance by withdrawing and depositing money, not just by telling the banker how much you want to change it to. Include a constructor with parameters used to assign values to both attributes. Users should be able to withdraw money from an Account, deposit money into an Account, find monthly interest rate, and find monthy interest. Include methods for each of these actions. More details on them below. withdraw method This method simulates withdrawing money from the Account. It should not return a value and take the amount to withdraw as a parameter and reduce the balance by this amount. deposit method This method simulates depositing money into the Account.…1.
