Pretty descriptive. Enough to understand what is what.
I would love to see something like that but for modules if it’s not yet posted.

Definitely a good amount of information to get me started with Ruby and eventually Rhodes Mobile framework. I have experience with C# and Java, and this tutorial is very helpful to me. Bookmarked !!

First of all, a great post!
Coming from a strong Java background, it took me a little getting used to concise syntax of Ruby, but this post really help me relate to my knowledge of Java. Thanks again for the great post!

I am not experienced in Java and have only programmed in Ruby and I must agree with other commenters that this is one of the better explanations of the Ruby Class that I’ve come across .

So, in my mind, anyone who is looking for a good discussion of Ruby Class can benefit from reading this article – not just Java programmers new to Ruby.

Thank you – I’ll definitely be reading other Juixe Techknow articles given the quality of this one.

First, thanks as this is a much better introduction to Ruby classes than the three other popular sites I just tried.

2 Q’s:

1) If you define the accessors using:

attr_accessor :fname, :lname

then aren’t these two attributes pretty much just public? If you later decide that you need to do some functionality after assigning, say, the lname field (let’s just say increment some internal counter), then how would you do that? Would you need to back out of the shorthand version of declaring these two generic accessors and instead spell out each one?

2) I noticed the if statement appears to be reversed from all the syntaxes I’ve ever seen. That is, the statement is before the condition. But I’ve also seen Ruby code with if statements that “read forward”, like other lang’s. Is this optional in Ruby?

Thanks,

John

This article helped me a lot, because I know a lot about Java, and almost nothing about Ruby, so it was useful to have some kind of comparison.
Thank you!

Great intro to Ruby Classes thanks!
I’ve been to a few other sites and too many seem to just throw in the dynamic accessors and move along without really explaining what they just did there…I finally get whats going on.
