Name:

Employee

Fields:

- name : String

- idNumber : int

- department : String

- position : String

Methods:

+ Employee()

+ Employee(name : String, idNumber : int)

+ Employee(name : String, idNumber : int, department : String, position : String)

+ getName() : String

+ getDepartment() : String

+ getPosition() : String

+ getIdNumber() : int

EmployeeDemo.java Code

public class EmployeeDemo
{
public static void printInfo(Employee e)
{
System.out.println(e.getName() + ", " + e.getIdNumber() + ", " + e.getDepartment() + ", " + e.getPosition());
}

public static void main(String[] args)
{
Employee e1 = new Employee();
Employee e2 = new Employee("Bill Gates", 1975);
Employee e3 = new Employee("Steve Jobs", 1976, "Design", "Engineer");

printInfo(e1);
printInfo(e2);
printInfo(e3);
}
}
