Hi,
When you use the word “private” to clear private methods - what does it
mean that only code within the object’s methods can access those private
methods? Can someone give me a simple example of this?
Thanks!

That’s basically correct, yes. Technically it means that the method
cannot be called with an explicit receiver:
class Foo
def pub
return “public method”
end
def call_priv
priv
end
def call_priv_explicitly
self.priv
end
private
def priv
return “private method”
end
end
f = Foo.new
f.pub
=> “public method”
f.priv
=> private method `priv’ called for #Foo:0x10016a1b0 (NoMethodError)
f.call_priv
=> “private method”
f.call_priv_explicitly
