Java is the first language I learned in my career. Its structure is foundational in my early years of understanding programming concepts. After going through several other languages with very different approaches, I’ve widened my point of view. Today, I want to reflect on the idea of inheritance. Inheritance in Java In Java, the idea of inheritance is tightly coupled with the concept of subtyping. Subtyping is the implementation of a IS A relationship.

Implicit returns are a feature in some languages. They have recently bitten me, so here’s my opinion.

A lot of literature is available on the subject, so I’ll paraphrase one of the existing definitions: An expression usually refers to a piece of code that can be evaluated to a value.

This is the 10th post in the Start Rust focus series. The Gilded Rose Kata is a refactoring exercise. The full description is available on GitHub. Nowadays, the kata is much more widespread. It’s available in plenty of languages, even some that are not considered mainstream, e.g., XSLT or ABAP. In this post, I’d like to do it in Rust.
