Programming - Java tutorial |

On this page, you will find lessons to get
started programming in Java. No previous programming experience is
needed (I think) but it helps.
When I started programming Java, I found it difficult to find information that could really help me on my way to get started. In this tutorial, I will try to provide some information for the absolute beginners to start programming Java. First, I will explain how to make a working programme. Only after the basics, concepts like object orientation and heritage will be discussed. We will be working with a DOS/UNIX command line window and a text editor. No IDE´s (Integrated Development Environment) will be used to program. To program and run Java programmes yourself, you will need a compiler and the so-called ´Java Runtime Environment´. I would suggest that you download ´ JavaTM 2 SDK, Standard Edition, v1.4´ or higher from the internet site http://java.sun.com/j2se for your platform and install it. Note that these packages are between 30 and 40 Mb. Furthermore, you will need a text editor such as Wordpad or download Textpad from http://www.textpad.com for extended functions. Textpad is a plendid programme. Lesson Zero: Setting up your programming environment. Lesson One: The first programme that does absolutely nothing at all. Lesson Two: Your first object. Lesson Three: Putting code into methods. Lesson Four: Adding components in your window. Lesson Five: Variables and Layout. Lesson Six: Making the ´+´ button work. Lesson Seven: A good example of making a button work. Lesson Eight: Making all buttons work. Lesson Nine: Reading values from the text fields; calculating and displaying the result. |
