Question about defining class methods

[Robo]

When defining class methods, are these two ways the same? Is there a
preference on which one should be use?

class Monkey
def self.method1
puts "method1"
end

def Monkey.method2
puts "method2"
end
end

I would think self.method1 is more preferable 'cos it doesn't have to
get rename when the class name gets change.

Also, I see them get call in two different ways, Monkey.method1 and
Monkey::method1. Both seems to work, are they identical? Is there an
idiom on which way should be use?

Identical.

True.

They are the same too. The only time they may differ is when a method begins
with a capital letter (which is very rare) then Monkey::Method1 would not
find it b/c it was looking for a constant called Method1 instead, to fix just
add (), i.e. Monkey::Method1().

I think the general convention is to use "::" for constants and "." for
methods.
