002_Using_Employee_Class.rb

# Create employee from our new Employee class
e = Employee.new(“Michael Koby”, 55000, “Dev”)

# Use change_department method
e.change_department “IT”

# Verify the department changed
e.department # => "IT"

# Give the employee a raise, via the give_raise method
e.give_raise(0.08) # => 59400

# Set the employee's age
e.age = 32 # => 32

# Output nice tab delimited output to screen using the to_s method
puts e.to_s 
#Result: Michael Koby    32    IT    59400
