| | | | | In the summer of 2021, I got my Java 11 certification. I expected it to be quite a breeze, because I'd been a Java developer for 14 years and surely I should have seen it all by now, right? Turned out I was very wrong. I came across lots of things that I didn't even know were possible with Java.

| | | | | One of the core features of modern Java is lambda expressions. Introduced in Java 8, lambdas provide concise syntax allowing the deferred execution of a block of code. Put a different way, lambdas allow us to pass behaviour as a method parameter. When the method executes, the lambda expression is run. This capability is often referred to as behaviour parameterization. Behaviour parameterization can be achieved in a number of ways, of which lambda expressions are usually the most convenient, and they are definitely the most concise. But what is behaviour parameterization, and why would we want to use it? To motivate this discussion, let's work through a real-world example of filtering a list of items according to some criteria. More concretely, let's investig... | |
