Collection classes in Java 6

Collection classes in Java 6

This is an overview of the main collection classes and interfaces for Java 6. I created it when I were preparing for the Sun Certified Java Programmer for Java 6 Standard Edition certification. But I have found that it also is useful as a reference when I am working so I often have a hard copy of it beside on my desk. It is shared here to let you also use it as a reference on your desk while you are doing Java development.
