Abstract
Based on source code reuse, class collaboration diagrams are widely used to glean insight into the interactive relationships among modules in a software system. The relationships seem complex and dazzling but behave in accordance with some potential connectivity laws. Many studies have shown that the evolution theory of complex networks can be a useful approach to the topology analysis of class collaborations. This chapter chooses the prevalent Java Development Kits to study the topological structure, small-world features, and connectivity of actual Java class collaboration networks. The empirical analysis discovers the small-world features of the class collaboration relationships. But the connectivity shows a great distinction between the active behavior and the passive behavior among those relationships, that is, the behavior to import Java classes approximately follows a decaying exponential distribution, while the behavior that Java classes are imported by others obeys a decaying power-law distribution.
