How to create email address generator with Ruby?

  def emails
    i = 0
    number = rand(252...4350)

    males = ["tom", "jack", "adam"]
    females = ["elizabeth", "rose", "juliet"]

    surnameMales = ["oak", "yew", "timber"]
    surnameFemales = ["rosewelth", "gates", "jobs"]

    providers = ["gmail.com", "hotmail.com", "yahoo.com"]

    while i <= 100 do
      @addresses << 
    end
  end

What I want to do is pick a random number, name, surname and provider and put them all together + attach a random number at the end of the surname so that it looks, for example, like this: [email protected], but kind of got stuck at the point where I have to put the whole thing together. As you can probably tell, I want to create a 100 random emails for testing purposes.

Can you please point me out how I could do what I have intended to do with Ruby?

Use a combination of string interpolation and Array#sample.

"#{females.sample}.#{surnameFemales.sample}#{rand(252...4350)}@#{providers.sample}"
>> "[email protected]"

Is your goal to do this as an exercise or is this just something you're trying to get done? If it's the latter, install the faker gem and just use it:

Faker::Internet.email #=> "[email protected]"

For 100:

100.times.map { Faker::Internet.email }

There's a couple ways to join strings in Ruby. Inline placeholders seems to make the most sense here:

@addressess << "#{ males.sample }.#{ surnameMales.sample }#{ number }@#{ providers.sample }"

In a double-quoted string, #{ expr } is evaluated and subbed inline. "#{ 1 + 1 }" outputs "2", for example.

Also a couple ways you can distinguish male or female — for example, checking if a random number is even or odd:

name = if rand(1..100) % 2 == 0 ? "#{ males.sample }.#{ surnameMales.sample }" : "#{ females.sample }.#{ surnameFemales.sample }"
@addresses << "#{ name }#{ number }@#{ providers.sample }"
