Guys,

         Do you aware about the method invocation in ruby using different ways?

 want to know? There are 3 different ways to invoke a method in ruby.

a) Using period operator

    eg. we have class called 'Car' and we need to access the method called 'car_detail'

    car = Car.new

    car.car_detail

b) Using .send method

    car = Car.new

    car.send(:car_detail)

c) Using .call method

    car = Car.new

    car.method(:car_detail).call

So, these are the three ways to invoke method in ruby.  Hope this post will help you.
