Question

URGENT! I NEED THIS WITHIN TWO HOURS TO PREPARE TONIGHT FOR MY FINAL EXAM TOMORROW!

Create a class called Employee that includes three instance variables—a first name, a last name, and a monthly salary. Code the default (no-args, empty) constructor. Provide a set and a get method for each instance variable. If the monthly salary is not positive, do not set its value.

Answer:

Here is the code you need:

class Employee
{
String first_name;
String last_name;
double monthly_salary;
  
Employee()
{
first_name="";
last_name="";
monthly_salary=0;
}
  
public String get_first_name()
{
return first_name;
}
  
public String get_last_name()
{
return last_name;
}
  
public void set_first_name(String first_name)
{
this.first_name = first_name;
}
  
public void set_last_name(String last_name)
{
this.last_name = last_name;
}
  
public double get_monthly_salary()
{
return monthly_salary;
}
  
public void set_monthly_salary(double monthly_salary)
{
if(monthly_salary>=0)
this.monthly_salary = monthly_salary;
}
}
public class Main
{
   public static void main(String[] args) {
  
       Employee ob = new Employee();
       ob.set_first_name("ABC");
       ob.set_last_name("DEF");
       ob.set_monthly_salary(250);
      
       System.out.println(ob.get_first_name()+" "+ob.get_last_name());
System.out.println(ob.get_monthly_salary());
   }
}

Output:

ABC DEF 250.0
