Interfaces in Java Java / General Development
In Java, a class can have at the most one immediate superclass. Multiple inheritance, where a class has more than one superclass, is not allowed in Java. However, one cannot ignore the importance of multiple inheritance because a large number of real-life applications require the use of multiple inheritance. Java provides an alternative approach to support multiple inheritance by introducing a new data type known as interfaces. Although a class cannot inherit multiple classes, it can implement more than one interface.

Java Programming Language Basics - Reflection Basics and Class Class Java / Getting Started
The standard J2SE platform libraries include a reflection API. This API allows classes to reflect on themselves, to see their inner selves. Typically not used by developers, but by tool developers such as those creating an IDE like NetBeans, the reflection API lets you discover the names of classes, methods, and fields.
3 base classes for a Java game programmer Java / Miscellaneous
This article describes a system of three classes I wrote for making Java games. You may use them for learning or for making your own games. You will only
