Working with Multiple Carets in IntelliJ IDEA

Sometimes you need to modify multiple lines of code on separate lines inside IntelliJ IDEA with the same change.

The fastest way to achieve that is with multiple carets that are either stacked vertically in a list, placed at the end of each line or positioned exactly where you want them in your code.

Debugging Tutorial 1 – Introduction: Conditional Breakpoints

In this series, I’ll walk you through the process of debugging applications and finding issues within them.

Git Archeology: Go Back & Forward in Time

Most people will start with using “git blame” (or the respective functionality within their IDE/editor).

But on most non-trivial projects, you usually end up with a refactoring commit, a rename, or a trivial cross-project fix like switching to another assertion library. At first glance, we only see the most recent changes, not the most important ones.

We need to carefully remove layer by layer of sand and dirt that has been swept over the real changes to unearth them.

The Debugger Checklist (Part II)

In the Debugger Checklist (Part I), I introduced some of the high level concepts and reviewed some of the common things you can do.

In this part, we’ll get down to the process. Again, it’s important to stress that this is boiled down and concentrated!

The Debugger Checklist (Part I)

Win at debugging by following an organized process and leveraging the tools you already have!

We’re going to skip ahead to a point where you have a bug you can reproduce (consistently or otherwise) but you don’t understand or can’t prove the cause.

Getting Started with Java 17 and IntelliJ IDEA

A new Java release every six months can be exciting, overwhelming, or both. Given that Java 17 is also an LTS release, it’s not just the developers but enterprises also noticing it. If you have been waiting to move on from Java 8 or 11, now is the time to weigh its advantages.

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.

Everyday Shortcuts in IntelliJ IDEA

Let’s take a look at some of my favourite keyboard shortcuts in IntelliJ IDEA.

It’s really helpful to use keyboard shortcuts because it speeds you up and keeps you in the flow of coding!

Get Your JDK As Easily As Possible!

Have you ever been in the situation where you’ve been looking for a specific JDK version of a specific distribution?

Sometimes that was easy… sometimes it was hard… but it never was fun.

After creating the Disco API (“Universal OpenJDK Discovery API”, in full) which serves up JDK distributions as a service, I had the idea to create plugins for IDEs to enable people to download the JDK of their choice more easily.

JavaFX: Gluon Status Update, Dual Screen on Raspberry Pi Sample, IntelliJ New JavaFX Project Wizard

Since Java switched to a 6-month release cycle, JavaFX has done the same, so next version will be number 17.

Keep in mind, although Java and JavaFX are on the same version-number, you can still use Java 11 and combine it with the JavaFX 17 runtime if you want to benefit from its improvements. Up till now, there were no breaking changes in either of the frameworks which force you to use a Java-version higher than 11.

Creating a Simple Spring Boot Application in IntelliJ IDEA

In this tutorial, we’ll use the New Project Wizard in IntelliJ IDEA to create a Spring Boot project with the Spring Web dependency.

We’ll also create a Spring Controller and served some text to the local Tomcat webserver.

Finally, we’ll add a test for our HTTP call.
