Measuring Cohesion and Coupling in Object Oriented System Using Java Reflection

Creating an efficient and effective system is a motto of a software engineer. The companies are spending 60% of cost for producing good quality software, software metrics require to measure qualitative in terms of software performance and reliability related characteristics like dependencies, coupling and cohesion etc. This paper proposes a set of new measures to find coupling and cohesion in a developmental system using Java reflection components to assess the usability. It will predict the fault in an object oriented system. Coupling and cohesion metrics are calculated by considering a number of relationships of a class. In this paper these metrics are calculated by using structural parameters like classes, methods and attributes. The structured information embedded in the source code. Classes, methods and attributes are retrieved in a package by using Java reflection. The retrieved information helps to measure the coupling and cohesion.
