Employee Class Create a class called Employee that includes

(Employee Class) Create a class called Employee that includes three instance variables—a

first name (type String), a last name (type String) and a monthly salary (double). Provide a constructor

that initializes the three instance variables. Provide a set and a get method for each instance

variable. If the monthly salary is not positive, do not set its value. Write a test app 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.

Solution

To run this application save both the files with the same class.

javaemployetest.java

public class Employee

{

private String firstName;

private String lastName;

private double monthlySalary;

public Employee(String name, String name2, double salary)

{

firstName = name;

lastName = name2;

monthlySalary = salary;

}

public void setFirstName(String name)

{

firstName = name;

}

public String getFirstName()

{

return firstName;

}

public void setLastName(String name)

{

lastName = name;

}

public String getLastName() {

return lastName;

}

public void setmonthlySalary(double salary)

{

monthlySalary = salary;

}

public double getmonthlySalary()

{

return monthlySalary;

}

public double yearlySalary()

{

double yearlySalary;

yearlySalary = (monthlySalary * 12);

return yearlySalary;

}

public double yearlySalaryIncrease()

{

double yearlySalaryIncrease;

yearlySalaryIncrease = (((yearlySalary() * (0.1)) + yearlySalary()));

return yearlySalaryIncrease;

}

public void displayYearlySalary()

{

System.out.printf(\"%s %s\'s Yearly Salary is $%.2f\ \", firstName, lastName,

yearlySalary());

}

public void displayYearlySalaryIncrease()

{

System.out.printf(\"%s %s = $%.2f\ \", firstName, lastName, yearlySalaryIncrease());

}

}

here is class employee test.java to test class employe.java

import java.util.Scanner;

public class EmployeeTest

{

public static void main(String[] args)

{

Employee employee1 = new Employee(\"first\", \"last\", 0.0);

Employee employee2 = new Employee(\"first\", \"last\", 0.0);

Scanner input = new Scanner(System.in);

String firstName;

String lastName;

double monthlySalary;

System.out.println(\"Enter details of employee1:\ \");

System.out.print(\"Enter First Name: \");

firstName = input.next();

employee1.setFirstName(firstName);

employee1.getFirstName();

System.out.print(\"Enter Last Name: \");

lastName = input.next();

employee1.setLastName(lastName);

employee1.getLastName();

System.out.print(\"Enter Monthly Salary: \");

monthlySalary = input.nextDouble();

if (monthlySalary > 0) //if monthly salary is not positive do not set its value

employee1.setmonthlySalary(monthlySalary);

employee1.getmonthlySalary();

System.out.println();

System.out.println(\"Enter details of employee2:\ \");

System.out.print(\"Enter First Name: \");

firstName = input.next();

employee2.setFirstName(firstName);

employee2.getFirstName();

System.out.print(\"Enter Last Name: \");

lastName = input.next();

employee2.setLastName(lastName);

employee2.getLastName();

System.out.print(\"Enter Monthly Salary: \");

monthlySalary = input.nextDouble();

if (monthlySalary > 0) employee2.setmonthlySalary(monthlySalary);

employee2.getmonthlySalary();

System.out.println();

employee1.yearlySalary();

employee2.yearlySalary();

employee1.displayYearlySalary();

System.out.println();

employee2.displayYearlySalary();

System.out.println();

employee1.yearlySalaryIncrease();

employee2.yearlySalaryIncrease();

System.out.printf(\"Congratulations to %s %s and %s %s. You just earned\"+ \" for yourselves a 10%c increase in your yearly salaries. \"+ \"\ Your new yearly salaries are:\ \ \", employee1.getFirstName(),

employee1.getLastName(), employee2.getFirstName(), employee2.getLastName(), \'%\');

employee1.displayYearlySalaryIncrease();

System.out.println();

employee2.displayYearlySalaryIncrease();

}
