Explanation / Answer

class Employee {
//Defining variables as private so that restrict the access outside the class
private String firstName;
private String lastName;
private long ssn;
private int employeeid;
private String department;
private String jobTitle;
  
//First Constructor of assigning default value as "unknown"
Employee(){
this.firstName = "unknown";
this.lastName = "unknown";
this.ssn = 0;
this.employeeid = 0;
this.department = "unknown";
this.jobTitle = "unknown";
}
//Second Constructor of assigning defined values while creating the class
Employee(String firstName, String lastName, long ssn, int employeeid, String department, String jobTitle){
this.firstName = firstName;
this.lastName = lastName;
this.ssn = ssn;
this.employeeid = employeeid;
this.department = department;
this.jobTitle = jobTitle;
}
//setter methods
public void setFirstName(String firstName){
this.firstName = firstName;
}
public void setLastName(String lastName){
this.lastName = lastName;
}
public void setSsn(long ssn){
this.ssn = ssn;
}
public void setEmployeeId(int employeeid){
this.employeeid = employeeid;
}
public void setDeparment(String department){
this.department = department;
}
public void setJobTitle(String jobTitle){
this.jobTitle = jobTitle;
}
//getter methods
public String getFirstName(){
return this.firstName;
}
public String getLastName(){
return this.lastName;
}
public long getSsn(){
return this.ssn;
}
public int getEmployeeId(){
return this.employeeid;
}
public String getDepartment(){
return this.department;
}
public String getJobTitle(){
return this.jobTitle;
}

public static void main(String args[]){
Employee emp = new Employee();
System.out.println("Employee FirstName:"+emp.getFirstName());
emp.setFirstName("Prakash");
System.out.println(emp.getFirstName());
Employee e = new Employee("Sindhu","Vegi",1234,123456,"Production","Analyst");
System.out.println(e.getDepartment());
}
}
