The Aspect Oriented Programming is a new programming paradigm that provides a means of encapsulation of crosscuting concerns in software. This paper describes a formal semantics of advice weaving in AspectJ, an aspect-oriented programming language that extends Java. The advice weaving is performed on the bytecode in regions of the code that correspond to join points declared by point-cuts. Aspect] provides two kinds of pointcuts: Static point-cuts and dynamic poinctuts. The static pointcuts quantify over static properties of join points, and thus correspond directly to locations in the bytecode whereas dynamic point-cuts quantify over dynamic properties of join points and can not be definitely mapped to places in bytecode. In this paper, we focus only on static pointcuts.
