Hello!
Im reading through tutorials to teach myself Ruby. I'm a business
programmer by day, but I want to learn something new instead of the same
old thing I've been doing for the last 8 years. I don't know any Ruby
programmers local to me, so I'd like to ask you to please code review
the first half of my 'project'. If I am doing something wrong, or could
do it better please remember Im just a ruby-noob so please explain it as
best you can so I can understand why I should do things differently.
Thank you much in advance!
Here is what I was asked to do (note this is only the first half of the
project, but Id like to know Im headed in the right direction before I
start the second half).
···
==================================================
# Name the project as MyOwnRubyApp.
# Create a new Ruby class called MyOwnRubyClass.
# Define a method called my_own_ruby_method inside of the MyOwnRubyClass
class as following
* The method receives two parameters called my_parameter and
your_parameter.
* The method then prints out current time using Time.now.
* The method then invokes yield(my_parameter, your parameter,
current_month).
o The current_month, is an integer value representing current
month of the year, for example, for the current month of "June", the
current_month should be 6.
o The current_month value needs to computed in your program. For
example, if you are running the same program during July, it should be
set to 7. (In other words, you cannot pass hard-coded value in your
program)
# Create an instance of MyOwnRubyClass. Assign it to a variable called
my_instance.
Here is my code. It runs but I get this error also "...My
Documents/NetBeansProjects/HomeWorkLab1/lib/main.rb:23: warning:
multiple values for a block parameter (2 for 1) from .../My
Documents/NetBeansProjects/HomeWorkLab1/lib/main.rb:17"
==================================================
# Create a class called MyOwnRubyClass
class MyOwnRubyClass
# define a method called my_own_ruby_method
# method receives two parameters called my_parameter and your_paramter
def my_own_ruby_method(*parameters)
# method prints our current time using Time.now
yield(Time.now)
# 1) The method then invokes yield(my_parameter, your parameter,

# 2) The current_month, is an integer value representing current

current_month = Date.today.month
#yield "#{parameters.join(',')}", current_month{|x| puts x} # doesnt
work
yield(parameters, current_month)
end
end
my_instance = MyOwnRubyClass.new
my_instance.my_own_ruby_method("alpha", "beta"){|s|puts s}
