Question

Write a Java class called Employee (Parts of the code is given below), which has three private

fields firstName (String), lastName (String) and yearsEmployed (double). Implement

accessor/mutator methods for the private fields and toString() method, that returns a String

representation, which contains employee name and years she was employed.

public class Employee {

private String firstName;

...

}

Write a client program called EmployeeClient that creates an instance of Employee class, sets

values for the fields (name: John Doe, yearsEmployed: 4.5), and prints out the information about

an object.

Please note that you need to create 2 source files – one for the class implementation

(Employee.java) and one for the client code (EmployeeClient.java).

Answer 1

EmployeeClient.java

public class EmployeeClient {

   public static void main(String[] args) {
       Employee emp = new Employee();
       emp.setFirstName("John");
       emp.setLastName("Doe");
       emp.setYearsEmployed(4.5);
       System.out.println(emp);
   }

}

Employee.java

public class Employee {
   private String firstName , lastName ;
   private double yearsEmployed ;
   public Employee() {
      
   }
   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 getYearsEmployed() {
       return yearsEmployed;
   }
   public void setYearsEmployed(double yearsEmployed) {
       this.yearsEmployed = yearsEmployed;
   }
   public String toString() {
       return "Name: "+firstName+" "+lastName+", yearsEmployed: "+yearsEmployed;
   }
}

Output:

Name: John Doe, yearsEmployed: 4.5
