Given nested modules Company::Department and a class Employee inside Department, how do you define a method info inside Employee that returns "Employee Info" and call it?
Amodule Company
module Department
class Employee
def info
'Employee Info'
end
end
end
end
puts Company::Department::Employee.new.info
Bmodule Company
module Department
class Employee
def self.info
'Employee Info'
end
end
end
end
puts Company.Department::Employee.info
Cmodule Company
module Department
class Employee
def info
'Employee Info'
end
end
end
end
puts Company.Department.Employee.info
Dmodule Company
module Department
class Employee
def self.info
'Employee Info'
end
end
end
end
puts Company.Department.Employee.new.info
Step-by-Step Solution
Solution:
Step 1: Define instance method info inside Employee class
Method info returns 'Employee Info' and is an instance method.
Step 2: Call method on new instance using correct module syntax
Use Company::Department::Employee.new.info to call instance method.
Final Answer:
module Company\n module Department\n class Employee\n def info\n 'Employee Info'\n end\n end\n end\nend\n\nputs Company::Department::Employee.new.info -> Option A
