public class Employee {
    private String firstName;

        this.firstName = firstName;
        this.lastName = lastName;
        if (monthlySalary >= 0) {
            this.monthlySalary = monthlySalary;
        }
    }

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

    public String getFirstName() {
        return firstName;
    }

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

    public String getLastName() {
        return lastName;
    }

    public void setMonthlySalary(double monthlySalary) {
        if (monthlySalary >= 0) {
            this.monthlySalary = monthlySalary;
        }
    }

    public double getMonthlySalary() {
        return monthlySalary;
    }
}


public class EmployeeTest {
    public static void main(String[] args) {
        Employee joe = new Employee("Joe", "Rogan", 9696);
        Employee tod = new Employee("Tod", "Howard", 8595);
        System.out.println(joe.getFirstName() + "'s monthly salary is " + joe.getMonthlySalary());
        System.out.println(tod.getFirstName() + "'s monthly salary is " + tod.getMonthlySalary());
        joe.setMonthlySalary(joe.getMonthlySalary() * 1.1);
        tod.setMonthlySalary(tod.getMonthlySalary() * 1.1);
        System.out.println("Salary after 10% boost");
        System.out.println(joe.getFirstName() + "'s monthly salary is " + joe.getMonthlySalary());
        System.out.println(tod.getFirstName() + "'s monthly salary is " + tod.getMonthlySalary());
    }
}
