Java Thread Programming (Part 2)

Let’s see an example of where we can use Threads. Let’s assume we are building a web server that returns the most used words in a website.

Java Thread Programming (Part 1)

We write code in a file line by line, and then it gets executed. To be able to execute a piece of code requires an execution environment. In Java, a thread is an executing environment. If a program has only one executing environment, then we call this program a single-threaded program.

Multiple Ways to Configure Spring

Many alternatives are available to configure your Spring app.

I’d like to list them in this post, leaving Spring Boot out of the picture on purpose.

JReleaser 0.7.0 Released!

JReleaser is a tool that streamlines creating releases for [Java] projects. This is a small release as core features are mostly complete.

Arrays and Object Reference Java Challenge Code Quiz

Arrays are objects in Java. Variables in Java actually store references to the object, instead of the real object.

When we pass an object reference to a method, we are changing the object that is in the heap of the memory.

Parallel Streams Java Code Quiz

Using streams concurrently with the parallel method is a good idea to optimize performance. However, it’s not always the case that we can use the parallel method, for example, when we depend on the order of logic execution.

Project Panama for Newbies (Part 3)

We are going to dig a little deeper in our exploration of Project Panama and how to talk to third party libraries such as SDL & OpenGL.

With the skills you’ve learned from Part 1 and Part 2, you should be able to call most of the common function signatures in many libraries out in the wild.

8 Debugging Tips for IntelliJ IDEA Users You Never Knew Existed

As developers, we’re all familiar with debuggers. We use debugging tools on a daily basis – they’re an essential part of programming. But let’s be honest. Usually, we only use the breakpoint option. If we’re feeling frisky, we might use a conditional breakpoint.

But guess what, the IntelliJ IDEA debugger has many powerful and cutting-edge features that are useful for debugging more easily and efficiently.

Daemon Thread Java Code Quiz

When we are working with Threads, it’s important to know when to use a daemon or a non-daemon Thread.

Do you know if the main Thread is a daemon or not? And do you know what a daemon Thread is?

That’s what you will find out by trying out the following Java Challenge!

Function Calculation Java Challenge

Functional programming is a very powerful paradigm that makes code more concise and easier to understand.

In Java, the “Function” functional interface can be used as a first-class citizen function, meaning that we can pass a function to a method and declare it as a variable, giving the developer a lot of power.

And now it’s time for you now to test your abilities with lambdas and functional interfaces!

Pi4J V.2 Released!

The Pi4J Project was started in 2012 by Robert Savage, the same year the Raspberry Pi was introduced.

After long rework, the Pi4J library (a friendly object-oriented I/O API and implementation libraries for Java Programmers to access the full I/O capabilities of the Raspberry Pi platform) has taken a big step with the first release of the V.2.
