Answer 1

Class Employee
public class Employee {
private String firstName;
private String lastName;
private double monthlySalary;
public Employee(String firstName, String lastName, double
monthlySalary) {
this.firstName = firstName;
this.lastName = lastName;
setMonthlySalary(monthlySalary);
}
public double getMonthlySalary() {
return monthlySalary;
}
public void setMonthlySalary(double monthlySalary) {
if (monthlySalary >= 0) {
this.monthlySalary = monthlySalary;
}
}
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}

public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
@Override
public String toString() {
return "first name:\t" + firstName + "\tlast name\t";
}
}
Class EmployeeTest
public class EmployeeTest {
public static void main(String[] args) {
Employee jackPerson = new Employee("Jack", "Pearson", 12000);
Employee luisLee = new Employee("Luis", "Lee", 25000);
System.out.println(jackPerson.toString() + "\t yearly salary\t" +
jackPerson.getMonthlySalary() * 12);
System.out.println(luisLee.toString() + "\t yearly salary\t" +
luisLee.getMonthlySalary() * 12);
jackPerson.setMonthlySalary(jackPerson.getMonthlySalary() +
jackPerson.getMonthlySalary() * 0.1);
luisLee.setMonthlySalary(luisLee.getMonthlySalary() +
luisLee.getMonthlySalary() * 0.1);
System.out.println(jackPerson.toString() + "\t yearly salary\t" +
jackPerson.getMonthlySalary() * 12);
System.out.println(luisLee.toString() + "\t yearly salary\t" +
luisLee.getMonthlySalary() * 12);
}
}
