Answer 1

All previous solutions with send are fine but it is recommended to use public_send instead (otherwise you can be calling private methods).

Example:

'string'.public_send(:size)
=> 6

Answer 2

You can also add hash to send parameters to the method.

send("method_name", "abc", {add more parameters in this hash})

Answer 3

Try using "send".

methods.each do |method| 
  self.send(method, "abc")
end 

Answer 4

Best way is probably:

methods.each { |methodName| send(methodName, 'abc') }

See Object#send
