Question

in Java, Create a class called EMPLOYEE that includes three instance variables – a first name (type String), a last name (type String) and a monthly salary (double). Provide a constructor that initializes the three instance variables.

Provide a set and a get method for each instance variable. If the monthly salary is not positive, do not set its value. Write a test app names EmployeeTest that demonstrates class EMLOYEE’s capabilities. Create two EMPLOYEE objects and display each object’s yearly salary. Then give each employee a 10% raise and display each employee’s yearly salary again.

Answer 1

class Employee{
        private String firstName;
        private String lastName;
        private double salary;
        //constructor to initialize the data
        public Employee(String aFirstName, String aLastName, double aSalary) {
                super();
                firstName = aFirstName;
                lastName = aLastName;
                salary = aSalary;
        }
        public String getFirstName() {
                return firstName;
        }
        public String getLastName() {
                return lastName;
        }
        public double getSalary() {
                return salary;
        }
        public void setFirstName(String aFirstName) {
                firstName = aFirstName;
        }
        public void setLastName(String aLastName) {
                lastName = aLastName;
        }
        public void setSalary(double aSalary) {
                if(aSalary>=0)
                        salary = aSalary;
        }
        @Override
        public String toString() {
                return "Employee [firstName=" + firstName + ", lastName=" + lastName + ", salary=" + salary + "]";
        }
        
}

public class TestEmployee {
        public static void main(String[] args) {
                //creating emp object
                Employee e1 = new Employee("Uday", "Kumar", 10000);
                System.out.println("Before salary hike");
                System.out.println(e1);
                // adding 10% hike to the salary
                e1.setSalary(e1.getSalary() + e1.getSalary() * 0.1);
                System.out.println("After salary hike");
                System.out.println(e1);
                
                
                Employee e2 = new Employee("Keerthi", "Kumar", 10000);
                System.out.println("Before salary hike");
                System.out.println(e2);
                // adding 10% hike to the salary
                e2.setSalary(e2.getSalary() + e2.getSalary() * 0.1);
                System.out.println("After salary hike");
                System.out.println(e2);
                
                
                
        }
