- Draw the UML diagram of the following class: public class Employee { String name; double salary; public Employee() { } public double getSalary() { return this.salary; } public String getName() { return this.name; } }Implement all the classes using Java programming language from the given UML Class diagram. Note: This problem requires you to submit just two classes: Circle.java, Circle.java, Rectangle.java, Square.java. Do NOT include "public static void main()" method inside all of these classes. Write a superclass called Shape (as shown in the class diagram), which contains: Two instance variables color (String) and filled (boolean). Two constructors: a no-arg (no-argument) constructor that initializes the color to "green" and filled to true, and a constructor that initializes the color and filled to the given values. Getter and setter for all the instance variables. By convention, the getter for a boolean variable xxx is called isXXX() (instead of getXxx() for all the other types). A toString() method that returns "A Shape with color of xxx and filled/Not filled". Write a test program to test all the methods defined in Shape. Write two subclasses of Shape called Circle and Rectangle, as…Consider the following class declaration: 1 public class Map 2 { 3 private String city = "Seattle"; 4 5 public void printCityName(String city) 6 { 7 System.out.println("The name of the city is " + city); 8 } 9 } What will be printed if we invoke printCityName("Boston")?
