You could do it with

<code>
class Login
    def with(params)
       @username = params[:username]
       @password = params[:password]
    end
end

login = Login.new
login.with(:username => 'aidy', :password => 'aidy1')
login.inspect # => "#<Login:0x24090 @password=\"aidy1\", @username= 
\"aidy\">"
</code>

but I'd go with

<code>
class Login
    def initialize(params)
       @username = params[:username]
       @password = params[:password]
    end
end

login = Login.new(:username => 'aidy', :password => 'aidy1')
login.inspect # => "#<Login:0x23d48 @password=\"aidy1\", @username= 
\"aidy\">"
</code>

as being simpler.
