If I understand your question correctly:

b = B.new
b.toto

or:

B.new.toto

Well, I probably misunderstood your it the first time around ;-)

Here's probably what you were looking for:

class B < A
def tata
toto
end
end

and then:

b = B.new
b.tata

or:

B.new.tata

Sorry, but I make a mistake my class are :

class A
def toto
puts "tttt"
end
end


class B < A
def toto
puts "mmmmm"
end

def tata

end
end

And I would like in B.tata to call the method toto of A.
