I need to do something like that
class Foo
define perform()
puts 'hello'
end
end
classname = 'Foo'
instance = create_instance(classname)
instance.perform();
Is something like that possible. If is the how?
Thanks a lot!

Defining a class in Ruby: Simply write class keyword followed by the name of the class. The first letter of the class name should be in capital letter.
An instance variable in ruby has a name starting with @ symbol, and its content is restricted to whatever the object itself refers to. Two separate objects, even though they belong to the same class, are allowed to have different values for their instance variables.
In the Ruby programming language, an instance variable is a type of variable which starts with an @ symbol. Example: @fruit. An instance variable is used as part of Object-Oriented Programming (OOP) to give objects their own private space to store data.
Ruby Class VariablesClass variables begin with @@ and must be initialized before they can be used in method definitions. Referencing an uninitialized class variable produces an error. Class variables are shared among descendants of the class or module in which the class variables are defined.
You could use const_get:
instance = Object.const_get(classname).new
instance.perform
