Problem 1: Create an Employee class

Create a class to represent Employee information called Employee. This class includes three pieces of information as instance variables—a first name (type String), a last name (type String) and a monthly salary (type double). Your class should have 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, set it to 0.0. Write a driver class named EmployeeTest that demonstrates class Employee’s capabilities. Create two Employee objects and display the yearly salary for each Employee. Then give each Employee a 10% raise and display each Employee’s yearly salary again.

Explanation / Answer

//Employee.java

public class Employee
{

//Declaring Instance Variables
    private String first_Name;
    private String last_Name;
    private double sal_ary;

//Parameterized Constructor
    public Employee(String firstName, StringlastName, double salary)
    {
       setFirstName(firstName);
       setLastName(lastName);
        setSalary(salary);
    }
   

//Getter & Setter
    public String getFirstName()
    {
        return first_Name;
    }
   
    public void setFirstName(String firstName)
    {
first_Name =firstName;
    }
   
    public String getLastName()
    {
        return last_Name;
    }
   
    public void setLastName(String lastName)
    {
last_Name =lastName;
    }
   
    public double getSalary()
    {
        return sal_ary;
    }
   
    public void setSalary(double salary)
    {
        if(salary < 0.0)
        {
           salary = 0.0;
        }
       
sal_ary = salary;
    }
}

//EmployeeTest.java
public class EmployeeTest
{
    public static void main(String [] args)
    {

//Creating two employee objects
        Employee employee1 = newEmployee("Joe", "Blow", 10000.00);
        Employee employee2 = newEmployee("Jane", "Doe", 15000.00);
       
       System.out.println("Before 10% raise:");
       System.out.println(employee1.getFirstName() + "'s salary is $" +employee1.getSalary() +".");
       System.out.println(employee2.getFirstName() + "'s salary is $" +employee2.getSalary() +".");
       
       employee1.setSalary(employee1.getSalary() * 1.1);
       employee2.setSalary(employee2.getSalary() * 1.1);
       
       System.out.println("After 10% raise:");
       System.out.println(employee1.getFirstName() + "'s salary is $" +employee1.getSalary() +".");
       System.out.println(employee2.getFirstName() + "'s salary is $" +employee2.getSalary() +".");
    }
}
