Ruby convert string to method name

Question

I have two methods defined in my ruby file.

def is_mandatory(string)
      puts xyz
end
def is_alphabets(string)
      puts abc 
end 

An array containing the names of the methods.

    methods = ["is_mandatory", "is_alphabets"]

When I do the following

    methods.each do |method| puts method.concat("("abc")") end 

It just displays, is_mandatory("abc") is_alphabets("abc") rather than actually calling the method.

How can i convert the string to method name? Any help is greatly appreciated.

Cheers!!

Best way is probably:

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