Dive into the challenging world of software development
About the Book
Today's life is fulfilled with computers and software: Using a personal computer, this might be obvious, but regardless weather you use a mobile phone, a modern television or any smart device, internally all these devices are powered by a CPU and software. Whilst the CPU is just a part of the hardware (the things you can touch), the software determines the behavior.
Visiting the seaside might be wonderful. But it you dive into the water, you'll recognize a seemingly different world. Programming is a challenging task. If you start programming you'll not only get a different view of such devices. You will be able to design the behavior. So lets dive into this amazing world. Like scuba diving, you need to learn a lot before you're able to go in for vast tours. But divers may start soon with their first little practices combined with theory. And so you'll do with Java.
Using this book you'll start programming your first small application after a little preparation. Beside such practical tasks, you'll learn theoretical background. Step by step you will enhance your knowledge.
This might be a cheap book. You may change the recommended price down to 12 US$. Or pay whatever you want. I'm writing this book in my spare time. Maybe that's crazy, cause I could earn much by programming, but I like to teach people. Thus I would be proud, if you pay the recommended price.
I would be happy, if you learn a lot with the assistance of me and my books. Any feedback is appreciated.
This is a living book. Published first in a very incomplete state, I'm going to add or update content irregular. Once purchased, you are able to download all future updates without extra charge.
If you still know about programming foundations and may be some Java basics, I'll recommend this book's advanced sibling: Advancing Java.
If you prefer C# as language of your choice, then take a look at Beginning C#.
Enjoy reading and stay tuned!
