Question

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 1

public class Employee {

    private String firstName;
    private String lastName;
    private double monthlySalary;

    public Employee() {
        firstName = "";
        lastName = "";
        monthlySalary = 0;
    }

    public String getFirstName() {
        return firstName;
    }

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

    public String getLastName() {
        return lastName;
    }

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

    public double getMonthlySalary() {
        return monthlySalary;
    }

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