Being a child of the 1970s, my first encounter with programming was in the era of home computers. Those tiny machines (mine was a Laser 210) were usually fed with BASIC, the first programming language I learned. Later came C, Perl and a few more. During the 1990s I wrote a bunch of programs for the Atari ST series. The first decade of my professional career was (inevitably) Java. Today it’s mostly Kotlin.
You can get the book from the publisher Packt Publishing, via Amazon, or your local book store.
I also wrote a German book about Android development. The first edition was published in 2011. It has seen six editions. While it is now out of print, the latest edition is available online completely for free: https://openbook.rheinwerk-verlag.de/android11/
Back in 2007, German publisher Galileo Computing (later Rheinwerk Verlag) published the first edition of my book about the Eclipse IDE. There have been five editions. The successor was published by Hanser in 2018.
My first book was published in 2006. It shows how to make Java apps that look and behave more like native Windows apps.
