Lessons

Today we'll touch on functional programming. More specifically, we'll look at the difference between declarative and imperative programming. First, let's quickly go over the terms. Then we'll compare these programming styles and see...

In 2005, with the arrival of Java 5, we became got to know new entities called annotations. Annotations are a special form of syntactic metadata...

The main benefit of annotations doesn't come from using the ones that are already in the JDK. That said, there is rarely a need to create your own annotation. But if we're developing a large system or creating a separate library...

"Now let's create and use a couple of annotations." "For example, let's say we're writing a game engine. Our game has a lot of characters that fall into three categories: elves, palace guards, and villains." "As the game is developed, new characters may be added, and this will alter the game balance. Thus, it would be very convenient to assign each 'character class' its own annotation that describes its physical characteristics ..."

Creating annotations is a fairly simple process, although it is limited by some rules. Now we need to figure out what practical purpose they serve. Let's recall how we create our own annotation...

In Java, annotations are a kind of label in code that describe metadata for a function/class/package. The topic is complicated for beginners, but it's just right for your current knowledge level...

"Hi, Amigo!" "Hello, Rishi!" "The topic of today's lesson is sockets." "You already know that every computer on the network has its own unique IP address." "Yep." "Now imagine you have several computers, each running a dozen programs that access the Internet: Skype, ICQ, etc." "And these programs want to communicate with each other ...."

When we speak of networking, we cannot fail to mention the OSI model. In terms of this model, today we are most interested in the transport layer (4)...

Of all the concepts and terms associated with networking, a socket is a super important one. It indicates the point through which a connection occurs. Simply put...

Your task is to program a model of an parameterized island consisting of an array of locations (for example, a 100x20 matrix). The locations will be populated with plants and animals. Animals can...
