Create a class called Employee that includes three pieces of information as instance variables a first name (type String), a last name (type String) and a monthly salary (double). Your class should have a constructor that initializes the three instance variables. Provide a set and a get method for each instance variable. Write a test application named EmployeeTest that demonstrates class Employee's capabilities. Create two Employee objects and display each object's yearly salary. Then give each Employee a 10% raise and display each Employee's yearly salary again.

// This class holds the information about an employee It has setter and getter methods to set the values and retrieve the values of the instance variables

public class Employees {

	private String firstName;
	private String lastName;
	private double salary = 0;

	// The default constructor

	public Employees() {

	// This parametrized constructor is used to set the values of instance variables
