Answer:
Follows are the code to the given question:
public class Employee //defining a class Employee
{
String first_name,last_name;
Double monthly_salary;
Employee(String first_name,String last_name,Double monthly_salary)
{
this first_name=f_name// initialize value in first_name
this last_name = l_name; // initialize value in the last_name
this monthly_salary = m_salary; // initialize value in the monthly_salary
if (monthly_salary < 0.0)//use if to check monthly_salary is positive
monthly_salary = 0.0;//set value 0
}
void setfirst_name (String f_name)//defining set method to store first_name
{
first_name = f_name; //holding the value of first_name
}
public String getfirst_name ()//defining get method to return first_name
{
return first_name;//return first_name
}
public void setlast_name (String l_name)//defining set method to store last_name
{
last_name = l_name; // holding the value of the last_name
}
public String getlast_name ()//defining get method to return last_name
{
return last_name;//return last_name
}
public void setmonthly_salary(double m_salary)//defining set method to store monthly_salary
{
monthly_salary = m_salary; // holding the value of the monthly_salary
}
public double getmonthly_salary ()//defining get method to return monthly_salary
{
return monthly_salary;//return monthly_salary
}
}
Explanation:
In this code, a class "Employee" is declared that defines two string variables "first_name,last_name", and one double variable "monthly_salary". In the next step, a parameterized constructor is defined that stores the value into the variable, and use if block to check "monthly_salary" is a positive. It also uses the getter and setter method to hold and return its value.
