Develop an Employee class that contains first name, last name, rank, and salary. The class should have the following methods:

parameterized constructor

getters necessary for printing the report

formatName() method that returns a String with the name in the format last, first

Employee information is stored in a sequential text file named employees.txt. The file has the format:

employees.txt file:   text file with the following fields separated by spaces:

Fields

Description

First Name

string

Last Name

string

Rank

Empolyee.java

public class Employee {

   private String firstName;
   private String lastName;
   private String rank;
   private double salary;

   public Employee(String firstName, String lastName, String rank, double salary) {
       this.firstName = firstName;
       this.lastName = lastName;
       this.rank = rank;
       this.salary = salary;
   }

   public String getFirstName() {
       return firstName;
   }

   public String getLastName() {
       return lastName;
   }

   public String getRank() {
       return rank;
   }

   public double getSalary() {
       return salary;
   }

   public void setFirstName(String firstName) {
       this.firstName = firstName;
   }

   public void setLastName(String lastName) {
       this.lastName = lastName;
   }

   public void setRank(String rank) {
       this.rank = rank;
   }

   public void setSalary(double salary) {
       this.salary = salary;
   }

   public String formatName() {
       return lastName + ", " + firstName;
   }
}
