Question

Each question is independent of each other. I want you to do it without copying from other's work. Do not forget to add comments to explain how your codes are working! Comments must be brief, clear, and understandable. Do not write long sentences!!!

Create a class called Employee that includes three instance variables – a first name (String), a last name (String), and a monthly salary (double). Provide a constructor that initializes the three instance variables. Provide a set and get method for each instance variable. If the monthly salary is not positive, do not set its value. Write a test application named EmployeeTest that demonstrates class Employee’s capabilities. Create two Employee objects and display each employee’s name, last name, and yearly salary. Then, give each Employee a 10% raise and display each employee’s name, last name, and yearly salary again. UPLOAD Employee.java and EmployeeTest.java

Make sure the work should be done by your own, no copied work.

Explanation / Answer

Solution:

##########Employee.java

public class Employee {

   //Declaring instance variables
   String firstName;
   String lastName;
   double salary;
  
   //Parameterized constructor to set the fields values respectively
   public Employee(String firstName, String lastName, double salary) {
       this.firstName = firstName;
       this.lastName = lastName;
       this.salary = salary;
   }

   //Getters and Setters
   public String getFirstName() {
       return firstName;
   }

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

   public String getLastName() {
       return lastName;
   }

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

   public double getSalary() {
       return salary;
   }

   public void setSalary(double salary) {
       //Checking if the salary is a positive numbe ror not
       if(salary > 0)
           this.salary = salary;
       else
           System.out.println("Invalid Salary!");
   }
  
   //Method to raise the salary by some percentage
   public void raiseSalary(double percent) {
       this.salary *= (1+percent/100);
   }
  
}

###########EmployeeTest.java

public class EmployeeTest {

   public static void main(String[] args) {
      
       //Creating 2 employees objects.
       Employee employee1 = new Employee("Adam", "Li", 2000.50);
       Employee employee2 = new Employee("John", "Cena", 3000.10);
      
       employee1.raiseSalary(10); //Raising employee1 salary by 10%.
       employee2.raiseSalary(10); //Raising employee2 salary by 10%.
      
       //Displaying employee1 Salary
       System.out.println("Employee1 salary is "+employee1.salary);
       //Displaying employee2 salary
       System.out.println("Employee2 salary is "+employee2.salary);
   }

}

Sample Run:

Employee1 salary is 2200.55
Employee2 salary is 3300.11
