@mee213 looks great! perfect execution.

[mee213]

Not attempting TDD yet, just #1 and #2 of Eagle assignment, see vehicle.rb. I know I need help with this one!

[jwo]

With class variables, just doing is enough to initialize them. so your def initialize isn't needed

@@allvehicles = []

[mee213]

Not sure I understand your comment on Eagle exercise #1... when then does array get appended with new instance?

[mee213]

Oh, is this what you meant, taking out the

@@allvehicles = []

line?

[jwo]

Nope:

Remove:

def initialize
  @@allvehicles << self
end

And keep

@@allvehicles = []

[mee213]

OK, I've made the change, but still not clear... I understand I've created an empty array, but I don't understand how it gets populated?

[jwo]

OK, my apologies :(

This is perfectly fine

def initialize
  @@allvehicles << self
end

I thought you were doing this (which is quite common)

def initialize
  @@allvehicles << []
end

Sooooo. yeah. Everything was good on yours except the matching

[mee213]

ok... what do you mean by "except the matching"?

[jwo]

ok... what do you mean by "except the matching"?

I meant this comment #18 (comment)

[mee213]

Ok! Got it.
