You can easily try out the new features in Java 21 that I wrote about in the previous post. You don’t need to install anything. Just follow these steps:
Here’s how to do it in Ubuntu Linux:
Java has allowed concurrent programming since version 1.0 through the use of the Thread class.
This capability was introduced in 1996 (I celebrated my 18th birthday that year!), but it quickly became evident that it wasn’t straightforward. Larger and more complex applications required better tools to handle threads.
The standard Java library lacked essential constructs for modeling certain concurrent programming patterns, and the code was often hard to read and prone to errors.
Excell files circulate in the veins of large companies. Ther are times when you want to extract some data and you have to use Java language for this purpose. Let’s see how to quickly extract data from .xls or .xlsx files using Apache POI library.
Maven coordinates of the library(ies) can be found here: https://mvnrepository.com/artifact/org.apache.poi. Note that there are two types of excel spreadsheet formats and apache-poi project has two of its most important libraries to handle these data:
I registered in ChatGPT web page today. Here are my prompts and its responses. I’m not very creative, as you can see. Perhaps I don’t have enough faith in its capabilities to expect more than from a better search engine.

Notes about asynchronous programing in Dart. In this article I test and learn about two variants of writing asynchronous code in Dart: async/await and Future-based.
Welcome in a new series of articles about Dart programming language.
It is not a beginner tutorial. I focus mainly on features that may be surprising and/or interesting for a Java(Script) developer.
Slide notes are available here.
Start with these:…

Predictions by authors of Java JVM Trends focus on faster adoption of new Java features and long-term releases
I’m reading about the trends in IT and expected directions for companies, inverstors and business in IT world and one theme comes again and again as a common denominator of all the predictions. This theme is: the client. But we as individuals are not “the client”: we are “the revenue stream”. The real client (the one who gives money to software companies) wants the information and needs software professionals to dig that information in order to know:
In this article I’m going to explore what an API is, why we might want to change it, how to do it and how to do it safely.
