    Welcome to my page with tips on Java programming! This is a general overview, you won't find code examples (this is no How to do ... in Java? text; I do have some code examples elsewhere). As a beginner, please don't be overwhelmed by the large number of tools and resources. This page just wants to give an overview. You don't need all of the tools mentioned here and you might want to do some things different. These are just my personal recommendations. A lot of related links are given so that you can find out more if you are interested. As an example, it is mentioned that an obfuscator makes it harder to create meaningful source code from given bytecode. You may never need such a tool, it is just mentioned so that you know what it is, that it is possible at

  • Chapter 31: java.awt.image
    Producers, Consumers, and Observers Java's model for manipulating images is more complex than other models. Java uses the concept of image producers and image consumers. An example of an image producer might be an object responsible for fetching an image over the network, or it might be a simple array of bytes that represent an image. The image producer can be thought of as the source of the image data. Image consumers are objects that make use of the image data. Image consumers are, typically, low-level drawing routines that display the image on-screen. The interesting thing about the producer-consumer model is that the producer is "in control." The ImageProducer uses the setPixels method in the ImageConsumer to describe the image to the consumer. The best

  • Cheat Sheet for MySQL 4.x Schema
    Portions of the following are quoted from the MySQL web site. Observations and opinions expressed below may be useful to MySQL newbies (use this information at your own risk). Use the underscore character in your column names, e.g. first_name. Subsequently in your PHP scripts the underscore can be easily replaced with a space. Use only lower case letters to ensure portability to other system configurations. Avoid using hyphens in the names of databases, tables, and columns. Situations can arise where the schema is not portable to another system configuration if upper case letters and/or hyphens are used. Hyphens appearing in a double-quoted line of PHP code may be interpreted as a minus sign (crashing the script). Usage of SET and ENUM fields is tricky when
