The Portable Document Format (PDF) is not a WYSIWYG (What You See is What You Get) format. It was developed to be platform-agnostic, independent of the underlying operating system and rendering engines. To achieve this, PDF was constructed to be interacted with via something more like a programming language, and...

The reduce() method is Java 8's answer to the need for a fold implementation in the Stream API. Folding is a very useful and common functional programming feature. It operates on a collection of elements to return a single result using some sort of operation. Note: Folding is also known...

Regular Expressions (RegEx) are a powerful tool and help us match patterns in a flexible, dynamic and efficient way, as well as to perform operations based on the results. In this short guide, we'll take a look at how to validate email addresses in Java with Regular Expressions. If you'd...

Regular Expressions (RegEx) are a powerful tool and help us match patterns in a flexible, dynamic and efficient way, as well as to perform operations based on the results. In this short guide, we'll take a look at the built-in RegEx methods, which are a part of the String class...
Regular Expressions (RegEx) are a powerful tool and help us match patterns in a flexible, dynamic and efficient way, as well as to perform operations based on the results. In this tutorial, we'll take a look at how to validate an phone number in Java, using Regular Expressions (RegEx). If...
In this article, we'll take a look at how to deep and shallow copy the objects in Python. The short answer is that you can use methods of the copy module, for both operations: import copy shallow_copy_list = copy.copy(original_list) deepcopy_list = copy.deepcopy(original_list) Though,...

Regular Expressions (RegEx) are one of the most powerful tools in programming, yet they're also commonly misunderstood. They help you match patterns in a flexible, dynamic and efficient way, as well as allow you to perform operations based on the results. This can include validating certain patterns that exist in...

The findFirst() and findAny() methods are terminal operations (terminate and return results) of the Stream API. Yet, there is something special about them - they not only terminate a stream, but also short circuit it: List<String> people = List.of("John", "Janette", "Maria&...
Let me preface the potentially provocative title with: It's true, nobody wants overfitting end models, just like nobody wants underfitting end models. Overfit models perform great on training data, but can't generalize well to new instances. What you end up with is a model that's approaching a fully hard-coded model...
