Comparative Impact Analysis (CIA) and Predictive Impact Analysis (PIA) are two methods of determining change/modification impact analysis on object-oriented software systems. JFlex, an object- oriented software tool, implements CIA and PIA for Java systems. With JFlex, software maintainers gain immediate knowledge of complex relationships in Java systems such as inheritance and aggregation by using the Extended Low-Level Software Architecture (ELLSA) model. The ELLSA model is built by examining the Java system’s source code. The demonstration will show how JFlex allows maintainers to create the ELLSA of a Java system, perform maintenance activities on the system, and then create a second ELLSA of the system and compare this to the first in order to determine changed components and ripple effect impacts resulting from the maintenance activities (CIA). The demonstration will also show how JFlex can be used to predict ripple effect impacts on an unmodified Java system by creating the ELLSA for the system and allowing the maintainer to ask “what if” questions pertaining to possible changes to the Java system. The resulting analysis helps maintainers to determine testing requirements and which other components must be changed as a result of the proposed modifications. JFlex is implemented in C++ under Microsoft Windows using MFC to construct the GUI. Keywords Object-Oriented Impact Analysis Object-Oriented Maintenance Object-Oriented Software Architecture
