“The use cases gave me ideas on how to refactor the code in my own Ruby program. The Execute Around use case paradigm has significantly cleaned up my code already.”Kevin Allen “I'd read about Ruby blocks before, butnothing really clicked until I worked through this course. Thanks for ...
besides being object-oriented, Ruby also allows procedural and functional styles of programming. The procedural paradigm refers to an instance where procedure calls are interpreted as function calls. However, functions do not exist in Ruby, and, therefore, methods can be created outside classes. Loo...
Let's look at the following types of loops in Ruby:while/do loops until/do loops do/while loopsThe while/do LoopAnother foundational concept for program flow is being able to repeat sections of code until a condition is met. These are called loops and in Ruby there are many ways to ...

(Ruby silently adds these functions to the Object class, maintaining the object-orientation behind the scenes.) Most interestingly, for Java programmers looking for new and useful perspectives, Ruby supports the functional paradigm. You can use most functional programming constructs in Java, with some...
And all of this began with the simple decision to learn a new programming language. As I continue my journey down the Ruby Railroad, I’m starting a side venture as a blogger on Medium. Most of my posts here will be cross-posts to articles I write on Medium. But I might still add ...
Ruby is purely an object-oriented language. This means that arrays are objects themselves. The full Object Oriented Programming (OOP) paradigm is valid for Ruby constructs throughout the application. We can use inheritance, polymorphism, and encapsulation in our application....
A solution to this somewhat more advanced Python programming problem would be to useatexit.register()instead. That way, when your program is finished executing (when exiting normally, that is), your registered handlers are kicked offbeforethe interpreter is shut down. ...

JRubyis an implementation of theRubyprogramming language to run on the Java Virtual Machine. The JRuby language is high performance and multi-threaded, with a vast variety of available libraries from Java and Ruby. Also, it combines features from both languages like object-oriented programming and...
