ruby send method passing multiple parameters Ask Question

Trying to create objects and call methods dynamically by

Object.const_get(class_name).new.send(method_name,parameters_array)

which is working fine when

Object.const_get(RandomClass).new.send(i_take_arguments,[10.0])

but throwing wrong number of arguments 1 for 2 for

Object.const_get(RandomClass).new.send(i_take_multiple_arguments,[25.0,26.0])

The Random Class defined is

class RandomClass
def i_am_method_one
    puts "I am method 1"
end
def i_take_arguments(a)
    puts "the argument passed is #{a}"
end
def i_take_multiple_arguments(b,c)
    puts "the arguments passed are #{b} and #{c}"
end
    end

Can someone help me on how to send mutiple parameters to a ruby method dynamically

send("i_take_multiple_arguments", *[25.0,26.0]) #Where star is the "splat" operator

or

send(:i_take_multiple_arguments, 25.0, 26.0)
