Inspecting the data in the watch quickly is key to a fast and effective debugging session. Here’s how you can see the data that’s important!

Dial your debugging skills to 11 by leveraging some of the lesser known capabilities for debugging highly complex systems such as filters!

Java Architecture for XML Binding (AKA JAXB API) is a popular API for marshalling XML data. It’s a framework for mapping between XML documents and Java POJOs (Plain Old Java Objects, AKA regular Java classes) almost seamlessly. The API is …

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.

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

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.

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.

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.

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.

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.
