This is the last chapter of the Java Keyword series. This is probably the keyword I have used the least. In my 20 year career as a software developer, I have used this keyword once, and that was to make some addition to legacy code. The keyword native is a method modifier . Basically, it is a keyword that can only be applied to methods. According to the Java Language Specification (JLS), A method that is native is implemented i...
I have been reading about Design Pattern lately, and I ran across some articles about the Builder Pattern that are not accurate at all. Because of that, I decided to write a short article about what this pattern is and how to properly implement it. I will start by providing a short description of what this pattern is. I will follow that with some context by providing hypothetical usages for this pattern, and conclude with a (hopefully good) code example. What is the Builder Pattern? Even these bad articles got one thing right: The Builder Pattern is a Creational Pattern . This means that the pattern's main goal is to provide a reusable solution for creating objects. You may ask, why are there more than one creational pattern? Isn't invoking a class constructor enough? Well... yes and no. Why use Builder Pattern?
